Re: QUESTION!!!!

you have a mechanical fuel pump, but it is not an injection pump, the high pressure oil pump opens and closes your injectors, and the fuel pump does just what its name indicates. what are you getting at with this? or were you just wondering?

Re: QUESTION!!!!

An Enhanced OBDII diagnostics tester can read out HPO pressure.

Re: QUESTION!!!!

Ok so I have narrowed it down to either my anti drain valve is stuck open or the o-ring on my stan pipe is bad. Anyone got any knowledge about how it check or change them?
