In case you want one other thing to check before you climb back under the car to take a closer look at the fuel pump... The AAR (you know what/where the AAR is?) is wired in parallel with the fuel pump. You can pop the connector off the AAR and probe the connections inside to see the same signal that the fuel pump should be seeing. Put a little noid light across those two terminals if you get energetic. Something you can see easy from the driver's seat.
So just like the fuel pump, the AAR should have 12 volts across it's two terminal connections:
- any time the key is in the START position, and/or
- any time the key is in the ON position and there is air flowing through the AFM.
So, if you've got power to the AAR at the correct times, you're looking for a bad fuel pump or connection to it. But if you're not getting the correct signals at the AAR either, then you've most likely got a problem with your FI relay.
Just thinking it's easier to check for that signal standing up at the front of the car instead of laying on your back under the rear of the car.
And, unfortunately, rossiz is correct that his trick with the oil pressure signal won't work for your year. That only works on 78's.
