truck just shut off on me and wont restart i had my auto enginuity hooked up and was reading some pressures I was wondering what my Injection control pressure should read and what my IPR percentage should be. Im getting only about 1300psi on my icp sensor and it is new im lost.

your getting thirteen hundred at cranking? if its above 500,your fine..have you had the sct updated??? what year ya got???

oh sorry its a 2005 and no that not cranking going down the road under a load was 1300 at idle it was about 500 and then when it died when i tried to restart it i was getting no higher than 350. I resealed the hpop and did the sct update new IPR vavle new ICP sensor i had the oil rails off cause i just did hg and arp head studs and new injectors and other stuff also.

Check IPR valve screen. Did you replace oil cooler when doing head gaskets? If so did you check channel to HPOP for debris and change pump inlet screen under oil cooler? Did you replace dummy plugs and standpipes when the oil rails were off?

NO i replaced the oil cooler earlier and i put a new screen in at that time. I didnt how ever replace the dummy plugs or stand pipes or o-rings on them i was just thinking about that last night maybe i have a high pressure leak there but do you know what ICP pressures are suppose to be.

Icp pressure needs to be 500 psi... you probably have leaks at the dummy plugs and standpipes...

how can you tell that is for sure the leaking spots can you pull covers and look

I actually heard it leaking in the motor it was that bad... but they are going to fail so you should just replace them all at once.. just remove the valve covers and you need a 10mm hex to remove them and a 12mm hex to replace them... the stand pipes are in two pieces the dummy plugs are one piece...
