    that one I don't know. I had forgotten you have that retarded rotor on those things. I really don't know where it thinks #1 is.

    Some development at last. Removed the fuel filter and the bitch wasnt pushin fuel. I checked the inertia switch and all the fuses, but where is the fuel pump relay? How should i begin to diagnose the problem? No pressure at the cfi shrader valve

    I think its on the driver's side fender. Thats where it is on an EEC-IV CFI car anyway.


    If you have power at the inertia switch, I believe the next stop from there is straight to the fuel pump. If the pump doesn't run, either its dead or the wiring between the switch and the pump is sketchy. The connector should be on the back side of the tank where you cannot access it.

    If you don't have proper manuals for this, these are likely close enough

    Dropped the tank and pulled the pump. I hooked it up to a straight 12v source, and the damn thing pumps right away. Voltage at the connector is usually 11.7, but can be unsteady, and ranges from the oddball 5ish volts to 12.4. Either way, the pump shows no signs of life when hooked up to connector. The circuit at the connector and the wiring inside the pump assembly have good continuity, yet i get no volt reading from the pump terminals whenever its hooked up.

    The mere fact that i get voltage at the connector means the relay and the fusible link are in working order right? Even tho the pump isnt dead it could still be dieing, considering my starting difficulties a few months ago?

    I have a set of Ford maintenance manuals for 1981, as well as a haynes. The haynes is particularly unreliable for EEC III info.

    If it reads no power with the pump hooked up, but power with no load you have a bad connection. Voltmeters represent almost no load, so even the most marginal connection will make the meter read with no pump hooked up.

    The trick now would be finding out whether its the + or - side. Try jumping a ground from the - terminal to a good ground and see if that makes it go. If not, its got to be a connection between the + terminal on the pump and the battery. Between those parts are the fuse link, the relay, and the inertia switch in the trunk, plus the wire and whatever connectors exist in that mess. You'd have to wire the pump up (or use a headlamp, something that represents a reasonable current load) and start chasing things backwards until you find the point where it has power again. The problem will be between that spot and the end of the line.
