sudden defueling

[squirtgun]

3 times in the last 2 months my truck has stalked while riding at a low speed(5mph to 7mph)I don't have a fuel psi gauge so I'm not sure what's causing it.Anyone have an idea?

I'd guess fuel filter. May want to move this to the 6.0 motor problems forum, might get more attention.

It got new filters less than a month ago.

I didn't post in the regular forums because the post end up lost in all the "which egr delete" posts

Fuel pump is my best guess at this point

I've got an "extra" HFCM from my Excursion from when I was having fuel pressure problems. My problem wasn't the HFCM but I replaced it and have the old one off my truck if you want to have it.

The truck died on me this afternoon.It wouldnt crack back up and had to be pulled home.
i install a new fuel pump,but now I cant get it to start. I have opened the fuel filter cap on top of the motor its getting fuel so now Im really lost. Anyone who might be able to offer some help would you please give me a call.229-344-5596

Check your FICM voltage and run a scan tool on it. Could very well be your HPOP. Thats my guess, but rule out the FICM first since its an easy check.

ICP sensor. Unplug it see if the truck starts

If it starts with the icp sensor(replaced 1 1/2 yrs ago) what does that mean?To this point I have been able to figure out most issuees with this beast,but now I'm stumped.
You could barely hear the oold pump priming,the one installed today is clearing fueling the system better.I did the KOEO priming 3 or 4 times before I tried starting the truck.
I spend $300 today in a new fuel pump(not entire HFCM) and new fuel filters.That just about wiped me out on cash flow until some customers pay so I'm hoping it's something simple I'm missing.Another $500+ on an hpop is not going to be a good thing.

Found the answer on the icp....I'll try that in a few minutes


*** Maybe I will in the morning it's on the back of the motor(why hasn't someone designed a relocation kit for those of us with older trucks?).This has me stressed out in a bad way I need to have it running ASAP I can't work without the truck to pull the pressure washing rig.

I replaced the icp today still no start just a looooong crank.

It's not throwing a CEL and I don't have a scanner I'm really lost now and I can't keep throwing parts at it.Please someone HELP
