HELP! Ran then shut off, now crank no start

[elite51203]

Just replaced oil cooler, started up no problem, ran for 15 minutes then shut off. Im out of ideas, energy and money! Ive unplugged ICP to see if it would start, but does not.

I have a 58V FICM and just installed an EGR delete.

I'd start with your connectors in the back of the FICM sounds like one might have not snapped in all the way then worked out while it was running

I've checked all plugs, everything is good. Now I've killed the batteries trying to crank it.

I've got a AE scan tool so Im trying to determine why it would run fine for 15 minutes and then just shut off!

Gotta have battery charger while cranking, trash probably went through the hpop, and shot it through the ipr. Take the ipr off, inspect the screen. If you read icp, it should be at least 500 psi, ipr 15-25%, if ipr is 85%, it is stuck open. This is a common problem posted all the time.

Sent from my phone that somebody didn't help me get.

I guess I'll have to get a battery charger and get the batteries charged bck up. PLease tell me that the intake doenst have to come out in order to get to the IPR...I have 06/04 build date. Engine says 2004on the sticker. Does it need an updated STC fitting?

Ipr can come out without removing the intake, it's a pain. You do not have an stc, did you update the dummy plugs, and stsndpipes?

I did not update dp and standpipes. I didnt have the valve covers off. All i really wanted to do was replace the oil cooler and repaired the cracked ypipe and egr delete. I got everything back together, checked for leaks, it ran fine for 15 minutes then just shut off.

Should I replace the IPR or clean it somehow? I really want to try and narrow the problem down before i dig back into taking things apart again!

Read ipr, and icp while cranking, that will tell you if you have trash in the ipr. Not too many people have had success cleaning the ipr, it's a case by case basis. Get those readings.

If it is indeed the IPR, i should replace it the entire unit, seals and filter? Any recommendations on where to get one?
