good afternoon my name is ***** ***** I will assist
first, I would get rid of the aftermarket injectors and get OEM from the dealer. the rebuilds have a high rate of failure from the start.
I would check the lift pump to be sure you have sufficient pressure to the pump.
ok, if the pump is working then it sounds like one of the injectors is leaking down causing low fuel pressure.
the key is the 2 o reilly injectors they may be causing this issue
if they are leaking, that will not be an accurate test
do you have a fuel pressure gauge that you can monitor the fuel pressure???
thats looking at the pressure up to the pump. you need to monitor the pressure right at the injectors
snap on, mac make diesel fuel pressure testers. I use the snap on, pricy but works well. you need to isolate the injectors
not looking at the lift pump. that just supplies the injector pump with fuel.
