2008 V-10 No Start

Hey folks,

Started my 2008 F-350 V-10 this morning in -15C weather with no troubles. Was running a few errands in town, and stopped twice turning it off. Came back out the second time, and it would not start. It turns over just fine, but it would not fire. I tried it in N instead of P and it made no difference. I must have tried a dozen times, and still no luck. At that point I called for a tow truck. About 10 min later I decided to try it one more time, and it fired right up! I cancelled the tow, and made it back home. I have started it again a dozen times, and its like there was never an issue in the first place. Not sure what to think...

Thanks for your help!

Had a similar issue on my 01 v-10, swapped out the fuel pump relay and have not had the issue again (its been about 2 or 3 weeks) so i am not 100% sure if that was the issue but so far so good idk about on an 08 but on mine it was a 15 dollar part and took 10 minutes to swap. So it might be worth a try if it happens again.

here is the thread i started on my no start issue a few weeks back. maybe it sounds like the same problem you where having?

Thanks for the info.

I'm thinking it was some kind of fuel delivery problem too. Of course it likely won't do it again, until I'm in the middle of nowhere and I really need it to start....

So naturally, the truck has been running perfectly the last few days. If it is going to give me trouble again, I hope it does it right at home in the driveway! Not sure what the odds of that are...

Haha I am in the same boat (although i am hoping i fixed it). If it happens again try banging on the dashboard above the radio and in that area. The fuel pump relay is located there (at least on a 2001) and when mine didn't start the second time that's what i did and it worked! lol

This afternoon, I replaced the FPDM. [fuel pump driver module] Apparently this is a very common problem on 05-08 Ford pickups.

I'm not sure if this was the problem or not, but it is a much cheaper and easier fix than dropping the tank to replace the fuel pump. Hopefully, it will not give me any more trouble.

So this morning it did it again. It was -20C here and it fired right up the fist time. I was moving a trailer around in the driveway, and turned the truck off after it had been running for about 10 minutes. I went to restart it, and no go. Turned over just fine, but would not fire. Tried it again 15 min later, and it fired right up. I checked for codes, and there were none.

Anyone have any suggestions or ideas?

Thanks.

my thoughts are that the battery, due being very cold, did not recharge enough to provide both the spinup starter and the electronic ignition the correct current and voltage level. I have seen this happen on vehicles under cold conditions.

easy fix is to put in a second battery, plenty of room under the passengers side chasis area. this will provide high amps and help prevent voltage drops.

alternatively, you can fully charge the battery with an extieror source, clean all battery charge related contacts, clean all grounds, and the usual "make it charge better" stuff.

replacing the existing battery initself won't help since battery CCA's drop with cold weather.

sometimes replacing a lundry list of parts fixes the problem, but not becuase there was a defect in the old part, but simply becuase removing the old and putting the new, knock the corrosion off the contact.

I don't believe the battery is the issue. It is less than a year old, and the engine cranks normally all the time. Its just that twice now, it will not fire after it has been running for 10-15 minutes. Wait another 20 minutes or so, and it fires right up.

Check fuel pressure while running and while cranking.

Sounds like your fuel pump might be getting hot, then it will fire when it cools back off.

Isn't the fuel pump inside the gas tank? If that is the case, then it is submerged in gas that also has a temperature of about -15C. Not sure how it could overheat.

I took the truck to my local garage, and parked it there overnight. It was very cold again, and it fired right up and ran perfectly. He tested the battery, and it is fine. Again there were no codes stored. Naturally, it would not repeat the issue I had with it, when it's there at the shop.... He suggested leaving it there again overnight, to try it again.

Not sure what else to do....

Left the truck there again overnight, and it is still starting and running just fine. He suggested changing out the crank sensor.

Not sure what else to try.
