Per Bentley 24.55, system should hold 29-36 psi for 10 minutes after
shutdown. If not, you check the systems by pinching off the fuel or vacuum
lines.  First, pinch line from pump, then move to the regulator vacuum hose,
then do each injector individually.  I've had good success with rebuilt
injectors, including from Rock Auto, where they are $20 each.

Subject: Re: 1987 2.1 WBX oil buzzer comes on after hiway usage...

  How can I test the injectors? (I have an fuel injection pressure tester...
but not sure if I can do much with it... pressure will leak down from other
areas (like pressure regulator or pump) sooner
I'd LOVE to do this without pulling the injectors out of the motor...  any
ideas?

Thanks,
Steve
