hey guys so i have replaced the icp sensor and ipr valve with the hopes that one of those were the cause to my no start, but no luck, truck started out struggling to do 70 mph then it kept loosing power thought it was fuel filters and air filter but had the same issue till if got so bad it would just crank over sounds like it wants to start but just wont, even with starting fluid it wont pop off (only did it once to test if it was starving for fuel) truck has a full 4" exhaust with an intake and programmer with egr delete heads have been done, if you need anymore info please just ask, also the ipr screen has some junk on the screen, intack tho but was also sucked in a littleways and appearse the new one is flat, not sure it that helps any, please any and all help guys!

 

Do you know what your ICP is? Needs to be around 780 minimum for it to start good.

 

they need 500 psi to start, if you were having trouble with it at speed then most likely the HPOP failed or you have a very bad HPoil leak, if you do an air test it will rule out the leak
