Ford 7.3L Power Stroke (1999-2003) :: 2001 - Strange Noise At Start Up?
May 17, 2015
I have a 01 f250 7.3. Every once and a while when I go to start my truck it make a strange noise, very similar to the sound a vehicle makes when you try and start it while it's running. if I let off the key and try again it will start. Sometime it will do it 2-3 times. So far I have never had it not start after a few tries. Can't seem to put a reason behind when and why it does it. Sometimes it will go weeks without happening, sometimes it will happen twice in a day. Starter is year old but put a cheap one in it. Is it my starter or something else.

I put a ts6 on my 2001 7.3. I love it shift points are better and truck has a lot more power. But I've noticed when I shift truck shifts into 3 (especially going uphill) I get a really weird turbo sound where it acts like its gasping for air (I have 6637 air filter) and then it shifts kinda rough into third. If I put chip on stock setting it doesn't do either of the things I described. Do I have loose turbo boots somewhere or possible bad turbo bearings?

Ok I have had this noise going on for about 1 week before transmission went out. I just built the trans and its still there.
I had a mishap years back with front end hub bearings so I replaced with New Timken Bearings. Well that wasn't it but at least I know where I
stand with those. It starts making a noise when slowing down about 3-5 seconds before coming to a stop. I thought maybe the carrier bearing in
driveshaft?
Pinion bearing in rear diff? I need to service the parking brakes on rear so I may pull it down and go through it.

I went on deployment and handed the wife to crank the truck up she did but didn't drive it so batteries didn't charge back up. I got them charged up and the truck cranked right up. I was plugging it in at night and it would start just fine the next morning. Then a week later batteries kept dying in a few hours during the day. Had to jump it again. then even when plugged in trying to crank it there was a buzzing noise and it would crank but not start. I bought new batteries and it cranked right up and drove fine until I shut it off and same problem and batteries were low again and it will crank but wont turn over. I am thinking maybe alternator.

I have a strange noise that occurs at both highway and surface street speeds. On surface streets at low speeds 45 mph and under, if I let off accelerator to coast and lightly step on accelerator I get this quick sharp noise.
Everything I have read regarding a similar noise is under load and being described as a turbo fart. Clearly I am not under any load. I'm lost.
Definitely not a low woooo noise. Also not a hard accel and release and definitely no chuckle and or popping. The sound is high pitched and quick, roughly .5 to 1 second at most. The sound is more like a "zzzrrp" or "zzzoop". I can replicate the sound 50% of the time easily at speeds under 45 mph by briefly coasting (no accelerator) and lightly tapping the accelerator and releasing or holding. Occasionally this sound will occur at full stop when I step off of the brake pedal and before I step on the accelerator. This sound can also occasionally be heard at highway speeds under similar accelerator conditions though it may be more frequent and I just don't notice it.
Would this condition throw a code? Just received "Total Ford Scan Tool Package Enhanced Bundle SP03" scanner from autoengenuity. Hoping to put it through its paces tomorrow.
Additional info: 145k miles. Injectors serviced by a reputable diesel shop here in Vegas approximately 1.5 years ago. Unknown oil leak where oil is collecting in the valley on top of the engine beneath the turbo. HPOP seals were replaced roughly 1 year ago at another reputable diesel shop here in Vegas. Still have an oil leak (turbo related?) Oil is under 500 miles old and acceptable level. Fuel filter is due for a change but that does not seem to affect condition. Air filter 1000 miles. Thinking about upgrading to AIS severe duty kit soon.

I have a 2003 f250 with the 5.4 in it. When I bought the truck the odometer and fuel gauge weren't working. So I tried disconnecting the battery and when I hooked it back up the odometer started working again and the fuel gauge went from below empty up to full then just dropped back down to below empty and won't move at all. I haven't tried disconnecting the battery again. And I know more than likely I will have to replace sending unit but trying not to if I don't have to.

My truck occasionally gets a hot no start issue and it's been happening more frequently. Mostly it happens if I drive it up to operating temp turn it off for a short time, then try to start up again. Usually, if I wait 15min to an hour it will start up. It has died on me while driving too, then I have to wait and periodically try it. I've noticed in this situation that if my glow plugs turn on for only a short time, it won't start. But once the motor has cooled enough that the glow plugs stay on for the longer duration, then it will start right up.
I've replaced the CPS, rebuilt the IPR, did the ICP unplug test, rebuilt the injectors, replaced the fuel filter.
HPOP oil level is good, changed the oil maybe 500mi ago. When it's a no start, the low oil pressure gauge does start to read after some cranking, also the tach does read. It throws no DTCs. My reader isn't able to monitor live sensor data.
There is some oil in the valley, but I can't find the source. I think it's probably the turbo pedestal. What else should I check?

It's a 2001 7.3 crew cab short bed with 260000 miles it has an sct programmer,exhaust, sbc intake simple mods . One day I was driving and it shut off on me so my first thought was the fuel filter so I changed it and it start right away. Shortly later it did the same thing but this time changing the filter did nothing so I put in a cps sensor after reading that could be the problem. Which fixed it for a day or two now it will not start at all it just cranks. I have checked and I am getting fuel to the bowl I tried changing the cps again and also I have no tach reading when cranking. When I crank it my hpop is not getting any oil that is where I am at ?

IPR is new and all injectors are new, new gaskets and harness and new glow plugs new batteries. still just cranks and cranks. no oil pressure build up and no tach movement, oil level is good in HPOP. What could it be?

I have a 2001 E-350 with 7.3 that will not start on its own. It is showing only 80psi ICP while cranking. It started with the aid of some starting fluid it will run at 550 psi ICP but the ICP duty cycle is running over 20%. We started with less than 10 psi while cranking and after a new IPR was installed it's now at 80 psi while cranking. There is good battery voltage oil is at correct level the HPOP is full. I just don't know what to look at next.

I've replaced the alternator and starter recently and both batteries and the truck ran fine befor that. But it sat for roughly 2 months and now it seems as if its not getting fuel. Will start with a shot of ether but will die as soon at it burns it off

2001 f250 7.3 with 210,000 miles. Was running rough when cold and glow plugs were bad so I bought new glow plugs and had injectors rebuilt with 100% over stock nozzles. When I changed them I made sure I turned the motor with glow plugs out and pulled the drain plug in the head. Wanted to start it just to get the oil out before I let it sit for a few days til I got the tuner. It started fine and I let it run while I ran in the house and when I came back out about 1 min later it was off. Didn't want to start again. Just left it til I got the tuner on and It still doesn't want to start. What I should check? Turns over good and has good batteries. Also it's a hydra chip tuner with beans tunes. Darren weeks rebuilt the injectors.

So I have a 2001 f250 7.3l and on my way to work yesterday while driving down a hill I switched my ts 6 switch to 140 and it immediately stalled, so I pulled over and restarted the truck and it started up fine and I drove the rest of the way to work, I go to start it after work and it won't start, it just cranks and cranks and cranks, occasionally it'll fire and I got it to start and was able to rev it for about 30 seconds but then it died, disconnect the 6 position switch from the idm and tried but still nothing.
So today I replaced the ipr valve, got everything back together still won't start maybe a little worse now, I know it's getting fuel cause there's pressure in the bowl when I try to take it off, there's a new icp valve, cps, new fuel filter and new sending unit, the hpop is topped off. Also I noticed when I went to change the ipr the wires on the plug were bare and touching so I addressed that, I don't know what else it could be?

My 2001 7.3L Diesel has 222,000 miles on it. Yesterday I shut it off at a drive through window, went to start it and it just cranked, no start. The engine light and the wait to start light did not come on. I plugged in a code reader this morning and when I turned the key I heard a buzz and a click, I noticed the engine light and the wait to start light came on. I cranked it over and it started right up, when I unplugged the code reader, it died. Plug it back in and it runs, dies every time I unplug it.

I purchased this unit, non running, was told the HPOP was bad, after going through the unit top to bottom, Im stumped, below is a list of items serviced and or replaced with OEM parts.
0. changed oil and oil filter
1. Terminator 500 Hpop
2. New ICP
3. New HPOP lines.
4. New starter and solenoid
5. Serviced Turbo (rebuilt with new parts and WW wheel)
6. Serviced Injectors (shimmed) all test good.
7. new pass and driver harness, UVHC replaced, glow plugs replaced.
8. new heavy duty GPR
9. Tested IDM no issues.
10. Hutch mod on tank (re-circulator was stopped up) deleted it, added inline filter.
11. serviced fuel bowl with new parts, upgraded parts on fuel bowl new blow off valve, new drain valve, tested heater all good no blown fuses.
12 replaced faulty fuel pump
Might be leaving something out of this list, the truck has run but only for very short periods of time, (hence the dropping of the fuel tank)
fuel pressure at 70 psi, some white smoke, connected to on board computer, checked every conceivable possibility No DTC codes, my gut tells me it has to be fuel related but at this point I just have run out of things to check.
I have tested everything with a fluke multimeter, including the IDM and all the circuits to the 42 as well as all the way to the injectors and glow plugs and find nothing wrong all tests yield valid readings,
There may be other information available but my after market scanner does not show any issue, KOEO buzz test results good.
The three times I have had this unit running it was dumping lots of white smoke, however after the last round of dropping the fuel tank and replacing the fuel pump the white smoke has dropped to a minimum, but cannot get the truck to run, cranks, wants to start, almost starts, got it up to 800 RPM last try but just will not go beyond that point.
I cannot find anything wrong, must be something I am either missing or its something my cheap scanner can't pick up on.

I have. 2001 excursion with a 7.3l deisel. 167100 miles
It runs great but if it sets over night when the motor is cold it will not start.
You have to plug the block heater in for about an hour or more for it to start.
To me it seems like glow plugs are not working? It had new glow plugs out in from the po.

I have been having problems with my truck for about 6 months now. It start in Sept when my fuel pump went. I got a new pump and went to change it just to have the back clip break off. I fixed the line after getting 2nd degree burns from the boiling water I had to use to expand the line and installed the new fuel pump. Didn't fix anything.
At this point is was dropping below freezing every night ( I live in Canada in the mountains) so I thought it might be my plug relay again... changed that. After that my started has always missed so I figured I would change it out and sure enough the power bolt on the starter was broken. Changed it.
Then it started smoking and I read up on the quarter trick so I figured why not try that. I checked everything and they all checked fine but I am a glutton for punishment and figured I would do that valve cover gasket. So opened it up to find one of my glow plug wires on my harness was burnt up. I have a spare truck for parts so I grabbed the wire and replaced it. Still no change.
Today it was spitting out the usually raw diesel that I have gotten use to but when I was opening the gate to get a manlift for work I smelt oil just to find my turbo coved and the V had a small pool of oil happening there. I added 4L of oil and tightened up my valve cover back bolt on the passenger side... it may have fixed the leak but didn't have time to check.
I backed up to the manlift and it lagged a bit so I gave it a pump of the peddle and it died. Now it won't start. Charged batteries and tried after it cooled down but still no go.
In short my truck has been smoking for about 4 months now. It shutters at low RPM and stalls at the bottom of hills if I gear down on the hill (we have really steep hills around here). I have changed my oil three times in the last 6 months but it keeps coming out black (which it always has). No water in fuel or oil. Once and awhile it had problems starting when it was warm but after bellowing out massive amounts of smoke it would start. The truck turns over but wont start. There is no power where it died so I have to come home and charge the batteries every time they get low but even after it cooled down it still wouldn't start.

I am a new and very happy 7.3 owner. i have lurking around these forums and decided I didn't want to be a creeper anymore. So onto the fun stuff.
Yesterday my wife was exiting a freeway and the Ex shut off while exiting. once she came to a complete stop she tried turning it on and it would start then immediately shut off. she was able to turn it on and it would run then shut off as she drove across the intersection. once she made it across a good samaritan offered to park it for her. She noticed a little bit of black smoke but she told me that the guy was revving it to keep it running.
Luckily there was family at the mall and she waited for the flat bed to arrive. it sat for about 2 hours and they tried starting it and it would start then die. no more black smoke though. we had it towed to a diesel repair shop and they went to start it today and alas it started right up. they let it idle for 30 minutes and it was good. they test drove it and all good. they ran the codes and got the following:
P1876
B1352
B1483
U1147
One thing I did notice a couple of weeks ago, while driving on the freeway cruising about 65, the Ex surged a little and then ran fine. then another time it surged a little while idling. Some more info on the rig. it has a banks six gun tuner and has a cold air intake and exhaust. And it has a Banks Big Head wastegate. I bought the rig 2 months ago and changed all the filters and fluids.

Ok I've got an 01 F250 sd 7.3 with 257k on it it just started talking longer to start than it should it will do it cold or hot even if I shut it off at the drive thru takes it like 10 sec or more to fire. My question is I thought about purchasing a autoenginuity to find the problem but not sure the best place to get and what model I should get.

I have an issue with my 2001 f350 7.3 PSD. Intermittently it will not start. It will crank really quick, but will not even try to start. I think it is not getting fuel. There are no CEL codes and I have a WTS light and the tach is moving while cranking. I hear a clicking/buzzing sound coming from under te center opf the dash. When I hear that sound it will not start. checked fuses and relays and it started before. not sure if removing the fue made whatever reset. this has happened a couple times. Now it will not reset. When I remove the number #24 fuse under the hood, the clicking stops. when i crank it, but still doesn't start. When it starts in runs perfect. Drained the batteries trying to trouble shoot, but have them charger now.
