Update; I got a vacuum pump to test the fuel pressure regulator, drawing 25" and cranking still no fuel passed thru the pressure regulator. I removed the pressure regulator, applied 15" of vacuum and 40 lbs. of air to the supply side and still nothing passed thru the regulator. I uncovered the ECU to check, I glowed red. then flashed red 4 times then two series of red flashes 3 short, pause, one, then repeated. the green led never came on. Anyone have any ideas???

Take a real good look at that green "led". In our '92 the computer only has a red led. The green thing next to it is a little capacitor.
Ask me how I know...

I'm new to the forum, but was wondering if either you or djmcd49 still had copies of the vacuum diagrams for the Stanza. I just bought a '92 model. Bought Chilton's manual too and thought it would have included a diagram. Unfortunately, there's not even a diagram shown for that engine at all. If either of you still have copies, I would greatly appreciate it if I could get a copy for myself. Thanks in advance for any help given.
