Long crank after adding Racetronix pump

Re: Long crank after adding Racetronix pump

OK, so just did a pressure test,

key on it jumps to 45 psi then starts immediately bleeding off,
engine idling it hold pretty steady around 45 psi
engine revving causes the needle to bonce but seems to stay within about +/-5 psi of 45

after turning key off, it bleeds down to 0 psi in about two and a half minutes.

So how do I determine where its bleeding off from? since it just started I'm imagining it's got to do with the new pump.

Racetronix stuff is usually pretty good but, never say never.

The pressure behavior you list above means it could be a pump with a leaking ball check, but more likely, you have one or more leaking injectors.

The Factory Service Manual has a section on fuel pressure tests which you should do. The test procedure will guide you to the problem, be it the pump leaking or injectors leaking. Without that procedure, you're just guessing.

What are you seeing as the issue with the battery? That seems like its not the solution... numbers you posted look good.

Battery tested out bad and was replaced, so we'll see what the next couple days brings

I don't have an FSM, can anybody provide the procedure to me?
