Yes it will. Happened to me just last week. You can remove it and clean it. Here is one of the links that might help...

I have three spare IPR's, the one that quit on me the other day I just swapped out for one I have clean.

I will clean this one and I am sure it will be fine. Just takes the smallest little piece of crud to stick it.

p0340 is cam position sensor. I would say the most likely culprit and easiest fix for a no start.

CSIPSD: I did the whole disassemble, clean and reassemble to my IPR with no results. Truck still just cranks over...

twinboys: I just replaced my cam sensor at the beginning of this problem and my tach is working just fine... I haven't scanned the codes since but I am pretty sure I solved that issue.

Now that I cleaned my IPR I am really stumped. Any other ideas?? Thanks for all your help!

See if it will fire on ether. Make certain to disconnect the glow plugs. Make sure you are getting at least 100 rpm while cranking (minimum required for computer to fire injectors).

You need at least 450psi of HPO to fire the injectors. Starting on ether means nothing.

Time to get a scanner on it. Need to know whats going on. You said you broke the ICP sensor. Did you get a new one of those?

Need to know what your HPO pressure is when cranking.

Need to know what your duty cycle is when cranking.

Anyone around you have a good scanner or Auto Enginuity?

Yeah no, I am not going to throw any ether at it. I don't need to bend any rods and ruin my engine for good.

Yes I did get a new ICP on it the day I broke it. So that should all be good. Still had the original at 300K miles so maybe it was about getting time for that anyways... I will have a nice scanner on it tomorrow that'll tell me all so I will get it on there and check and let you know what the numbers come back with. Thanks!

Just for referance. The injectors will NOT fire without 450psi of oil pressure.
