03 f350 just up and died

[tburns00]

While driving home the other night from my kids basketball practice my truck just up and died. I was messing around since the roads were a little wet and was gonna gett the tires to break loose and slid the *** end around to get some kicks out of the kids since there use to riding in my mustang and we play around a little when the oppertunity is safe. Any ways back to the truck, i never got to even break the tires loose when it died. Ive recently put a new icp sensor and an upgraded ficm. It will crank but it wont fire. I know there is an injector going bad due to a little bucking while in od at crusing speed. The truck is stock other than a 4INCH lift and 35s. Any help would be much appreciated.!

Access to a good scan tool? you need to monitor your ICP desired and ICP actual pressures. Could be a HPO leak or a HPOP failure, how many miles on your truck? Ive seen most old style HPOP failures above 150xxx. Your year truck doesnt have the STC fitting or the leaky standpipes and dummy plugs but it doesnt rule out a HPO leak.

Pull codes and report back if possible, there will be codes even w/out a CEL.

The truck has 177k on it now. I havnt had a chance to tear into it yet due to the 6 inches of tain we have had over the past 4 days. Ill report back tomorrow after i run a scan on it and pull the codes.

I was able to scan the truck today. There were no codes stored in the computer
I guess my next step will be to pull the ipr.

[roche837]

No codes? surprising i would look at fuel pressure as my next route. pull the fuel filter cap and turn the key on see if the fuel bowl fills up

[roche837]

sounds like fuel pump to me

i just went thru this with my truck...its an '04. if the ipr and icp turn up good, you get fuel in the upper bowl and it cranks over fine start checking the all the connections in the wiring harness especially at the pcm. Mine ended up being loose and it had to go back to the dealer for a reflash. Got the truck back today and it runs just as good as ever.

Well i checked the fuel bowl and it fills up with the key on. Tried starting it again and still nothing. Checked the 3 pluggs going to the pcm and they were tight. I crawled under the truck and looked up towards the hpop and i had some oil on the back of the motor, kinda like it was when i changed the icp. I bought a new ipr for the truck (not installed yet) but im wondering if it could be the hpop leaking. If it goes bad will it throw a code? And also if it was the ipr it would have thrown a code I'd think. Any thoughts what direction i should take.

What were the numbers from the scan?

Did you get SYNC? This should have generated a code.
What was the voltage and FICM voltage? May or may not code if intermittent.
What was the IPR & ICP readings during the crank? Probably will not code.
Did you put on a fuel pressure gauge?

Let's start with the basics and move from there.

I got a sync but there were no codes. It has a new icp sensor. I never checked the ficm just due to the fact that i replaced it a few months ago. I guess it wouldn't be a bad idea to check it though.
