Ford F-150 (2004-2008) :: 2005 - Hesitation - Cranking But Not Starting
Dec 5, 2013
Quick truck stats: 2005 F150, 5.4L, 85,000 miles
The past few weeks my engine has been hesitating on some cranks before it would start. I figured it was due to the cold weather so didn't pay too much attention to it as it was also not throwing the check engine light.
Yesterday it didn't start at all after the several attempts of just cranking over and over. It still didn't seem to trip the check engine light but I pulled my scanner out anyways and it had the code p1237. I cleared it and the truck started right up. It even had no more issues the three times I started the truck after that.
Today, however, she is not starting again and not throwing any codes. Still cranking so I'm sure it's not the started or the battery. I'm going to have my husband pick up some starter fluid on his way home today to see if I can at least get a temporary start since I think it's the fuel pump, or possibly the fuel filter. It is cold again this morning so I'm wondering if the cold is somehow making this issue worse. Either way I'd like to fix it, since being stranded with a truck that doesn't start is not my idea of a way to pass the time.
What else it might be and how I might be able to diagnose it?

I have a 2005 F-150. Recently, I have heard an alarm like tone for five seconds or so after cranking up. Often, this sounds immediately after cranking up but sometimes, it happens a few minutes after cranking up. There is no light that accompanies it on the instrument panel and the sound stops after sounding for a few seconds and does not recur until the engine is started another time. What this might be?

How's it going? I have a 2005 F150 with the 5.4L V8. It has 70,000 miles on it and until yesterday and has been a great truck. While driving in traffic yesterday the truck started running rough and hesitating. It through two codes - misfire cylinder 5 and misfire cylinder 6.
In response, I purchased two new coils and 8 new autolite plugs. The plug installation went smoothly and the coils all went on without incident. However, this didn't fix the problem!
The next day I found that cylinders 5, 6, 7, and 8 were all having issues. At this point I also had an "O2 stuck lean" code so I pulled the plugs and found all four brand new plugs fouled and smelling like gas and an ehaust that smelled like raw fuel. This led me to replace the O2 sensor on the drivers side. With the new O2 my lean code disappeared but I still had a rough idle.
Further troubleshooting found that injector 6 was stuck open (which presumably fouled my O2 causing it to read lean and dump fuel thus fouling all the plugs on one side). I replaced the injector and the rough idle disappeared and all seemed really well as the truck idled in my driveway.
However, as soon as I hit the road I noticed a major hesitation. The motor is also noticeably louder and has a very hard time accelerating. I'm thinking that I've plugged up my cat by dumping so much fuel in to it and the hesitation is caused by a lack of breathing - does this sound possible? How would I confirm this without replacing the cat? Anything else I should look for? I'm fairly confident I have combustion in all 8 cylinders now so I'm leaning towards intake/exhaust issues.

How to diagnose what I think is a failing alternator?
Here are the symptoms:
- Hard starting in cold weather
- Battery not at full voltage when truck is parked (usually around 11.5-12 volts. I have been putting a charger on it some nights)
- Lights seem to dim when I've got accessories running, like heater fan, heated seats etc. Lights get brighter with engine RPM, like when pulling away from an intersection.
What's my next step to diagnose this? I did a search, and didn't see anything. My battery is probably still under warranty, so if that's the issue, it should be a free fix. How hard is it to install an alternator in a 2005 with 5.4L engine?

2005 F350 crew cab with 6.0 currently cranks but no start with a P2291 error code. Using scanguage 2 it shows icp 0, IPR 67.7, FICM 47.5 while cranking. Disconnected ICP and still no start. removed icp and hooked up air and I do not hear/see any signs of air leaking. When I disconnect the air it then whooshes out. About 2 months ago got a #1 cylinder contribution error code and changed out that injector and it has ran fine up until this issue.
Can this be a IPR? I am leading towards the HPOP, but as it costs a pretty penny would really love to make sure I tried every other avenue.
I have 197K on it, and 2 years ago did a EGR cooler delete. In May this year replaced the oil cooler, and then in August changed out the #1 fuel injector.
Oil cooler screen was broken. Cleaned the entire reservoir out. Could this just be a clogged IPR? or seeing the change while cranking an indication that it is working?

My daughter drives a 2005 Passat station wagon, has a small child and one on the way. She has had intermittent problems with the car just not wanting to crank. After sitting 15-20 minutes it will crank. But the wait and not knowing if it will crank is taxing me and her. Especially since she has another one on the way. She has taken it to a reputable mechanic. They kept it for 3 days, cranking it on and off without a problem, and told her they couldn't find anything.

My 2005 STX 4.6 fuel pump crashed a couple of months ago. A couple of days after having it replaced I started having hard/rough starting problems accompanied by a 0300 and 0301 code. I reset the codes several times and they only come back during the 3rd or 4th hard start, never while driving. The hard starts occur after the engine is shut off for more than a few minutes after driving. I have replaced the plugs, #1 COP, remaining COP boots, Cam Pos Sensor, Fuel pump drive module and had and FI. Also had the fuel pump replaced again on warranty thinking maybe a bad check valve. Again...it worked perfectly for a day and now I'm back to square one. Haven't gotten any codes YET but its only been a day. Bad injector? EGR?

2005 5.4L She would have a hard time starting before but after I replaced and fixed everything below she was running really good. Now back to sputtering, taking a long time to start and now not starting at all.
I have replaced; Fuel Pump, Fuel Filter, FPDM, Plugs and COP's, FRP Sensor, followed the power wire from the FDPM and found it corroded bad so I replaced it, also changed the ground location on the FDPM, I have checked all the wires from the FDPM to the drivers seat, checked all fuses.
I have power to FPDM and I have the diagram for the plug but how can I test (hotwire) the Fuel Pump without lowering the fuel tank? What should be the voltage coming from the FPDM plug? not sure about pin 1 & 6.
How can I test the FRP sensor? what are the specs for voltage?

In the last 50 starts it has happened twice: When I try to start the truck, all dash lights and power come on but there is no sound or cranking from the engine. If I cycle the key back and forth a half a dozen times it will then crank and start. Next time I will try and listen to hear if the solenoid is clicking.
I've read posts about it being the anti-theft, ignition switch, stater relay, ppm relay, etc....
I could replace the relays to rule them out, but my gut is telling me that's not it? Would there be a code from something like this?

I have an '04 F-150 4 x 4 Supercrew Lariat w/ the 5.4 V-8. It has 105,832 miles on it. No issues until a week ago. Battery light and "Check Charging System" message appear 30 seconds after cranking the engine. I have replaced the battery (Ford Motorcraft), belt and alternator (Motorcraft 130 Amp). Still getting battery light and error message. I've read some post that indicate it could be a short in the fuse box.

Here's the story on my truck. Spits and sputters between 40-60 during heavy acceleration and on rare occasions will jerk/pop while at a steady speed. No engine or wrench lights. I thought it might be the fuel filter and changed that, it didn't work. I also ran two bottles (on 2 separate occasions) of Duralube extreme fuel system cleaner, that didn't work either. So, I took it to the Ford dealer for a diagnostic. They had a hard time getting it to act up but said it finally misfired on #8 and recommended replacing the ignition coil and plug. I did that, still have the same symptoms. So, I thought it might be the fuel injector and changed that. Still same symptoms and ZERO dummy lights.
After several YouTube videos, I thought it might be the TPS and got one. Before I changed that however, I cleaned the Mass Air Flow sensor, still same symptoms. I finally changed the TPS, but the engine wouldn't start or run at all, no warning lights yet. When I put the old TPS on, it would run. I unplugged the TPS and it still ran but very rough. Now the engine light IS on! Thinking I purchased a bad part, I took it back to O'Reilly's and they warrantied it out and gave me a new one. I had 19 PO codes. I changed the TPS again, and, it won't start or run at all. Put the old one on and it runs. They cleared the codes and told me they think it could be the ECM/PCM.
Why will a new TPS not work? I still have the same issue of hesitation @ 40-60 during hard acceleration. No hesitation during a moderate acceleration.

This morning as I was driving to work, my truck hesitated as I tried to accelerate from a stop sign. I pressed the pedal and nothing, almost felt like it was going to stall. After about 3 seconds it started driving again and I had no further issues. It seems to only do this in the morning when it is cold. It has done this a couple of times before, but usually it recovers almost immediately. I had no CEL come on. 2007 F150.....

I have a 2008 Ford F150 4.6L and its been broken down in our shop for quite some time now. It started acting funny when I could not get the truck to do over 80kmh. Slow acceleration, and a horrible shaking when it idled. Eventually it was undriveable since I could go above 50kmh anymore. From looking online we replaced the plugs and coils. We removed the intake to find the gaskets were shot so coolant was leaking into the spark plug tubes which could've been the cause of a misfire. Fixed that. Still the same. We replaced the egr valve and dpfe sensor because we keep getting the P0402 excessive egr flow code. Still no luck. My dad is a journeyman hes just not too familiar with newer trucks.

What a year 2014 has been. I had a 2005 F250 6.0 that was stolen in March and totaled when found days later. My insurance gave me enough to pay off the loan and render me the obstacle of replacing it. I got my F250 pretty cheap so replacing it for the insurance pay out was non-existence. I ended buying a 2007 F150 EC 4X4 w/ the 5.4 and having 97,000 miles on it. Just as luck would have it, I had the F150 for about a week before the cam phasers went out. Luckily the warranty covered it enough to put in a new LKQ reman engine.
I got the truck back about 2 weeks ago and put 1,000 miles on it in a very gracious form. I have noticed since then that despite letting it warm up for 20 minutes, I could put the throttle on the floor and the outcome was very poor. It was almost as if I was attempting to pull a house down. I couldn't even get the tires to spin at all, not even on wet pavement. Now I know this is not my old F250 6.0 turbo diesel, but really, I expected more from a new reman engine! They used all components from the old engine except for new spark plugs and a fluid change. Why is this "new" reman engine so weak?

First, a little background on my truck. 2007 with 5.4, 122000 miles, oil changes with 5-20 Motorcraft and Motorcraft filters, plugs done by dealer 40000 miles ago. The truck has developed a ticking noise, kind of like a lifter (I know these engines don't have lifters) that is most noticeable from the side of the truck near wheel. ticking speeds up with the rpm. Also around same time, between 40-55 under load there is a bit of a stumble, but I can gas thru it. I'm guessing these are related. I'm thinking spark plugs again, but shouldn't I get more than 40000 out of them? I might just take it in, since I've got oil leak somewhere around back of the oil pan, but figured maybe might get some clues first. Also, no CEL.

1996 f150 sometimes it starts sometimes it don't. It is cranking over the starter is in gauging as well as the fuel pump I can hear it.... It's getting spark and I replaced the starter solenoid.

I have a 2004 F150 4x4 super crew with te 5.4L in it. Truck has 200K plus miles on it and I went to start it after driving (it may have say for 10 min) the truck hesitated and didn't start and smoke started coming from under the hood. Looked like it was coming from the drivers side maybe mid fender or closer to the firewall. Look at it and nothing was on fire but something defiantly happened cause now its compensating for something. The rpms are up from what they usually are and the drivers information was cleared. Truck runs now but just worried

My Honda Civic 98 starts funny. It will hesitate about 3-5 seconds before cranking and sometimes after starting the starter will grind momentarily before letting go.

I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.
