26-38 Psi
OK, here's where I'm at now.
What I have is the LE system from what I've gathered from all of your replies. No cold start injector. It took me 2 hours because I have very limited space in my garage and even more limited space in and around the intake manifold. Or maybe I'm just not aware of a quicker way. But basically, I had to take all the connections off of the fuel rail to re-connect the fuel pressure gauge. Now it is in the correct position to get the correct readings.
When I fired up the engine, I saw 30 PSI. It gradually dropped to 28 within a few seconds. Then I revved the engine a bit and the highest that it registered was 38 psi. As I continued revving the engine, I noticed that the lowest pressure was now 26 psi. It would sometimes rise a bit to settle at 28 psi. Then I'd rev the engine again and back down to 26 psi.
When I hold the throttle open, not WOT, then pressure reading initially goes up to a maximum of 38 psi depending on how quickly I open the throttle and then drops down to around 33 psi with the throttle opened to a steady position.
Does this sound more like a clogged filter than a bad fuel pump? Or maybe both?
Thanks,
Manny
