Ford Super Duty (1999-2016) :: 2002 F250 Randomly Dies While Driving When Hits Bumps And Won't Start Immediately
Sep 20, 2015
My 2002 F250 7.3 randomly dies while driving and seems to only be when I hit a bump no matter the size. I have checked the valve cover harness connector outside of the valve covers and they look fine. I checked the ECM connection took it off and reconnected it.
Changed the CPS censor twice, checked the ICP sensor, checked continuity of all the glow plugs through the valve cover harness. Checked the fuel pump, checked all related fuses, changed the fuel filter, checked glow plug relay, batteries hold good voltage and were recently upgraded to bigger batteries.
Engine runs just a little rough but not enough to be of concern. Air filter is clean and oil level is perfect. What could possible be causing my truck to randomly die when it hits a bump and not start back right away??? This truck is new to me and its the first diesel engine I have ever owned.

My truck will turn over very strong but will not crank. it cranked one time then died immediatly. 30 min later it cranked and ran for about 5 min then died again. Alternator, fuel pump.
Gas v10 motor, full of gas, new spark plugs.

So I'll be driving down the road and the gauges will randomly start jumping around then the truck will just shut off, this just started a couple days ago, it seems to be gaining in frequency, when i try and restart the engine all my warning lights flash on and nothing happens, try again and it starts back up, now the last time it happened all of the above happened but it was followed by a fast clicking noise from under the steering column, it has to be a electrical issue as i have full tanks and motor is in tip top shape. Also no codes pop up with my code reader.

I have a 2001 f250 super duty extended cab with the v10. Over the past week it has been running fine and it will all of a sudden lose power and dies. I've been able to start it back up once right away and a few times it started up after a few hours of messing with it.
So, after the truck dies it will crank and crank but will not start. We have checked fuel pressure and nothing. Then we applied direct current to the fuel pump and it turns on. Then we applied direct current to the fuel pump slot in the fuse box and got a fuel pressure reading of 40 psi. But when we crank we have no pressure.
When we apply direct current to the fuel pump slot in the fuse box the truck will only crank and not start.

My 1997 F250, 4x4, 460, auto has started dying with no warning while driving from 5 to 30 miles. Changed the fuel filter and the fuse under the hood. Where to start.

2002 F-250 7.3 4x4 ...
I have a rattling noise coming from the front suspension (both sides) when going over small bumps. Most people point to ball joints, but I find my case odd because I just replaced
Upper/Lower ball joints
Track bar
Tie rod ends
Shocks
Front U joints
Drag link
I did not touch the leaf springs or the sway bar, except to grease the links, which otherwise looked good.

OK, not sure where to start so here goes. I have an 02' f-250 with the v-10. I just had some minor front end body work done and when I got it back I noticed that it just didn't feel right while driving. When I start it, I notice a small misfire while I stand next to the exhaust outlet. Nothing too bad, still runs great. Shortly thereafter I started noticing a more habitual missing while driving. Roughly between 30-40 mph and around 12-1500 rpm the truck feel like the driveline is about to pickle fork the truck. If I let off the gas or step on it, the vibration goes away. And very intermittent.
It will only do it when the truck is warmed up. If I only drive about a mile, it won't do it, yet if I turn around and head back, there it is! Now the weird part. I for reasons I won't get into, I left my ignition on and drained the battery. I just replaced it and for the last 2 days nothing. Nt even a misfire. Now today here it is again. I have read all over the forums for this exact problem and cannot find my exact problem. I have replaced the plugs with Autolites and cleaned the coils as well as the boots and applied a small amount of dielectric grease to the top of the plug. The boots are cleaned and not a sign of cracking or wear.
I replaced the PCV valve and nothing. All the plugs looked exactly the same. Light chocolate in color. Not one looked different than the other. I took them out again last week to verify the plugs weren't bad and the new ones all looked the same as well. I cleaned the MAF sensor also. Just cannot figure out what could be doing this all of the sudden. I don't see where anything wasn't plugged back together when it was being worked on and why would a new battery make it go away for a short time? Oh, and lastly, I have a superchips programmer that came with the truck and there are no codes showing and my check engine light has never came on yet.

I have a 02' 250 4x4 with 250000 miles on it. While driving between 55 to 65 mph there is a roar and vibration that seems to be coming from the rear. I have about 35% tire tread left and have had the rear tires balanced and it still does it. Having issues with drive shafts unbalanced or rear ends?? I am not sure where to start....

Let me start out by saying that I have exhausted every option that I have read on every thread that I could find on the internet regarding my son's 2002 7.3L not starting. What I have is no 12v power to the starter solenoid at the starter when I crank the key. What we have done so far, had the starter and both batteries tested, all good. Swapped out the starter motor fuse and the starter relay. Tried a new ignition switch and a new trans position sensor. Found major corrosion in the fusible link junction box on the drivers inner fender so we cut out the fusible links and put in a temporary jumper wire, still no crank. I have power to the dash, power on the power cable at the starter. I can jump the terminals on the starter and the starter engages. I found the shifter linkage bolts loose under the dash and tightened them up also. We have been struggling with this for 3 days, out in the lovely Michigan weather, since it couldn't have died in his parking spot in our heated shop, and I am completely frustrated. Are we overlooking something glaringly obvious?

I have a 2002 f250 superduty 5.4 4x4 around 317xxx original motor and trans. When it's cold out it won't start at all I have to use starting fluid but once started it will start right back up. Did the plugs fuel filter cleaned the intake and sensors still have a problem plenty of fuel pressure plenty of cranking amps brand new battery and Alternator. It just cranks and cranks when it's warm out fires right up. Runs smooth no lack of power or misfire no codes are being thrown also.

2002 F250 V10....
Ambient temp is 4-9 degrees
Step-son borrowed truck. I started it at 9 in the morn and moved it to a different parking spot on street. No problem starting.
Step-son came at 11 and took truck. It started no problem.
He drove it to work. At 5 p.m. would crank, but not start. A jump got it running.
On charger all night. Would not crank this morn. Would not crank even when jumped.
Are we looking at a bad battery or something else?

Bought a 02 F250 5.4L a few weeks ago. i have replaced the coils and plugs, put in some fresh oil and some other minor things. Last weekend i drove over to my neighbors and back with no issues, until i went back out to start the truck an hour later.
The dash lights come on, but the engine wont start up. i hear a kind of whirring sound coming from a black canister under the hood on the drivers side. I cant use my code reader and I have pretty much exhausted my little piece of diagnostic knowledge. i originally thought it may have been a starter and got a fresh one ready to install but after thing about it i don't feel that's the issue.
I live in a very rural area and bringing it to a dealership would be a 150 mile round trip. What that black canister is? Why it won't start up?

I have an 02 250 5.4. 103,000 miles. My truck at random times will not start in below freezing temps. Turns over just fine but Acts as if a frozen fuel line. I can get it running by pouring hot water on the fuel rail or a shot of starting fluid or sometimes both. It's been going on about 3 or 4 weeks now and I have ran through 4 bottles of dry gas with about 15 gallons each time. Also have replaced fuel filter and fuel pressure regulator. I'm 99.9% positive the pump is working and there are no leaks in the lines or holes in tank that I can see. My next step is to drop the tank and clean it out but trying to avoid that.

I have a 2002 F250 7.3l with an aftermarket alarm. I can't read what the third letter is on the decal MV? 2000 Modular Vehicle Security. I added a pic of the alarm decal below. The key fob it had was aftermarket for the alarm and stopped working about a year ago. Today I unlocked the drivers door with the key and the lights started flashing and I can hear a clicking sound. It done this a few times back when the key fob still worked and I just kept hitting lock and unlock until it finally stopped. It won't let me start the truck at all and I have tried unhooking the batteries with no luck.

My 2002 F250 with the 5.4 (215,000 miles) has a loud tap upon start up, only on the passenger side, heard best in the wheel well. It only lasts about 30 seconds to a minute. It occasionally rears it's head driving around town but only intermittently. Just drove it 275 miles, at 13mpg, truck runs fine, just annoying.

1999 F250 SD Ex 4x4 V10 has been intermittently not starting, both cold and warm, began last fall but only happened once a month or so or longer. Would then start after trying again either right away or after waiting a bit. Now it is doing it on a regular basis. Sometimes it will start right away, sometimes won't but if you keep trying or wait awhile it starts, sometimes using the extra key will start it right away after the first one didn't, sometimes neither one. It does not try to turn over, make any noises, no warning lights flashing, just won't start.
Now also on two occasions within the past week, it just stopped while driving. Radio, dash lights, etc., stayed on. I got it to the side of the road with the little power steering left where it started up again right away.
No codes showed up. First mechanic couldn't find anything obvious or replicate problem. Changed air and fuel filters (fuel filter really needed changed), plugs. Got truck back and it wouldn't start next morning. He checked it again and got a code related to ignition, tried the spare key and it started up. Truck back home, next day same problem.
Mechanic 2 checked, no codes, kept several days but, of course, couldn't replicate problem. I'm not even sure what all they checked, used to be an excellent repair place but now they seem to only really on diagnostics and throw up their hands, very disappointing. Replaced solenoid and starter last year myself. Otherwise, have had no problems until this.

My 2006 6.0 shut off immediatEly after starting this morning and never started back up. I have a scan Guage 2 hooked up. I'm showing no ficm voltage and no sync even when cranking. I physically checked the ficm voltage with a dvm at the screw to the far right on the ficm, and I have 48 volts. Why do I have 48 volts at the ficm, but 0 volts showing on my scan guage? And no sync when cranking?

I have a 2002 F250 7.3L and it wont start. Its been sitting for the past few days in the cold because the batteries were shot but was plugged in the whole time. I replaced the batteries today and even poured diesel 911 5 hours before trying to start it in case the fuel was gelled. It cranks fine but just wont turn over.

Just bought a 02 f-250 7.3 with 115k miles. A couple days after I bought it I noticed a lot of white smoke on cold starts for about 20-30 sec at 50 degree temperature. So I tested the GPR which ended up being bad a replaced with the one that is double in size(name escapes me atm) and also did the 50 cent mod to keep the through-valve cover harness from losing connection since both sides were lose.
After that the temp warmed back up and it would only blow a "puff" of white smoke. The past two days it has gotten down to 30-32 and the truck has a rough time starting. Cranks fine but it's almost like it's getting choked or flooded then it will blow smoke for 3-4 minutes after it starts. The truck does have a FASS fuel system on it with stock injectors. Should I try to Ohm out the glow plugs again or where should I start trouble shooting?

2004 5.4L F-250 ... it's a one owner truck I bought brand new in 2003 and only has 50,000 miles on it.
I have the 2V 5.4 engine no tuner or chip. 4x4 with 4" lift and 35's and I changed the rear to 4.88's. I love the truck but my problem is when I hit a large bump or drive too fast on a dirt road the fuse#23 that controls the PCM will blow. Consistently. I have to keep a box of 20 amp fuses handy. I have a 2 post lift in my shop and have scoured over every wire that is connected to the fuse. The EVAP solenoid, AC Clutch, Transmission solenoids and the O2 sensors. I only have 2 sensors I could find one on each side of the headers.
I couldn't find any rubbing wires or exposed wires. I am at a loss. It only happens when I hit a large bump. Could it be the Torque Converter Clutch Solenoid?
My brother in law is a mechanic and he brought over the diagnostic computer and when it blew while hooked up he seemed to think it was the TCC solenoid because when it engages the chart shows it angling up but when it disengages it drops off straight like it should. My truck seems to run fine when the fuse isn't blown, but when it blows it goes into a limp mode with the tranny stuck in 3rd or 4th gear and I have to drive it home in 1st.

When I go over good size bumps, I hear a clunk in the front tire area when my driver's window is down. It's a metal noise, like something loose.
2011 F-250 with 203K miles. Replaced shocks last year. Did this with stock wheels/tires. Something in the front suspension or axles. What should I be looking at?
