Hi guys...
I have a no start condition on my 74 2.0 liter,D-jet. Seems like the fuel pump is not running. As per my crappy manual, I have checked for power at pins 87 and 86 where the pump relay plugs in. There is no power at either pin with the key on. Manual says if that is the case, then start checking ignition wiring. Obviously, I'm missing something. Swapped out relays with no luck also. Any help really appreciated.... Mike |

I agree with Curt on the later pumps.
As for testing the relays here are a couple of pics. + to 85, negative to 86. Meter leads yellow to 87, white to 30. No power = open Power applied = 0 + OR - a couple of ohms. You can take the top off of these and try to repair. I have done a couple. The very fine wire from post 85 or 86 can come unsoldered. By resoldering, the relay is good again.
