no start after injector change
ok changed number 8 injector due to redistribution code and miss. after changing truck would not start after multiple long starts. took everything back apart and double checked all removed parts orings all looked good cleaned everything and lubed orings before reinstallation. after reinstalling tried again icp pressure will not get above 130psi so i know that it is a high pres oil sys problem. truck was running fine other than the miss before this. oil pressure on the dash is good while cranking, cts reading while cranking not sure what else to monitor while trying. battery voltage 11-12v, ficm 50v, icp pres 130 max been reading and saw that you can unplug the ipr to get a base hpo pressure, should i try this? if so where is it? i also did an oil change in between the injector change so i know the oil lever is good and oil is correct. also could old orings on the stand pipe and dummy plugs cause this. dont want to buy anything else without narrowing down my issue. any help will be greatly appreciated.
also i did get it to fire with a quick spray of starting fluid so i know glow plugs are hot and timing is good. fuel pressure i am sure is good i just installed the blue spring a few months ago and i was driving the truck 20 mins before i started the injector change.
also had absolutely no starting issues ever with this truck would always start withing the first rotation or two of the motor not even 2 seconds of cranking
