ok, i rebuilt my engine, new rings, recoated pistons, all internals were checked and renewed as needed. reused 4 injectors the fifth would not come out so i rebuilt another head of another core.
tested leakoff with cold engine, after 2 ten seconds of cranking here are the results, does this need to be tested with the engine hot? excuse the dirty number one injector it came from another running truck and was the only loose injector after cleaning some black death from the other ones.
after starting the fuel rail pressure goes to 7000, i checked low pressure pump and it is giving 65 psi static pressure and 7/8 gallon flow in 51 seconds, 70 psi steady while running.
engine starts and promptly but upon reving it i get code P0088, I notice a change in engine tone after about 15 seconds after startup with it idling.
I changed the fuel rail and injector pump from a running engine and nothing changed.
I also notice that it sounded like one cylinder fired a couple times with the cam sensor unplugged during the leak off test.
Could my fault be in and injector being stuck open due to contamination or wear, what would be the best way to test them without going to the dealer?
