7.3 dies out new injector and HPOP

my buddy has a 2001 7.3 truck runs fine for about 30 miles then seems to starved fuel and knocks, then dies. He took it to Ford and they said the cyl. No.8 injector was bad and replaced it, the next day died out again took back to ford and they said that now the HPOP was what was causing the problems and then replaced it and the icp sensor. Any and all help would be greatly appreciated, thanks in advance.

nope, i always thought that if the cps or idm went out the truck would be DEAD. the truck will fire back up if it sits for a while.

an injector being bad will not generally cause one to do whats its doing , just skip , in my opinion a fuel pressure test needs to be run, im thinkin the screens in the tank are clogged up , need to check fuel pressure under load , i bet it dies off and could have contributed to the injector failing

when he took it in to ford to have the HPOP replaced a fuel pressure test was done and everything checked out fine, i suggested the screens in the tank, but the tech basically told me i couldn't tell my *** from a hole in the ground so i shut up.

So the HPOP and ICP were replaced and it still does it??? That's a lot of cash right there. Hopefully they didn't hit him for a new IPR with the pump...

yeah it was pretty expensive,although i almost had a heart attack when he told me it took them 3.5 hours to replace 1 injector, i've heard of all 8 being replaced in that amount of time.

Now Scuffy how many times have you seen that cylinder 8 contribution balance code set on those things.
I was told that the new style cam sensor will put that code in there and if it passes the buzz test they are fine.

3.5 for 1 injector is about right on for Customer Pay on an injector. I would have charge 1.0 diag and 3.0 for the injector.
