Got the car all back together it ran for a second on residual fuel from the injectors and thats it. Was trying to bleed the fuel line and realized the fuel pump wasnt running. Broke out the test light to find no power to the fuse, though it is grounded... so it would seem i have a short to ground someplace, now i would try to figure out the wiring diagrams i have but they are for a mondeo (i think, the ones for the windows and stuff are for a mondeo), not sure how similar the wiring is.

the car is a 97, the computer is from the 97, the harnesses are from the 98 and are from an auto, this car is MTX...


any insight or ideas would be great! thanks guys!

Check the wire harness under the rear seat. I've seen more than one instance where the wire harness was crimped under the seat from the factory and damaged. I forget, was the car running before the repairs?

Is there a high power (underhood) fuse for it, or possibly a fuseable link?

I don't have a wiring diagram handy for the Contour... BUT! Possibly... Fuel Cut off switch. I wouldn't think it'd wire first, then to fuse for fuel pump, then to fuel pump? Makes no sense since really everything should run though a fuse before anything else. I assume you have a FordContour.org/contour.org forum account? I know when I had my Contour GL (Which I miss so very much), they were helpful with issues I had. I know Contour.org isn't the same as what it was software wise, so I don't know if they are still helpful or not if any of the old members left.

Yeah, I heard rumors that site went to shit. I left after I got my Taurus, really, everyone was an ass toward the end. Then I lurked, then they did a site update, then I just abandoned it. I couldn't even find stuff I did there anymore.

Try FCO. It's generally slower than Contour.org, but the responses are more helpful.

Fuel Pump power is supplied by Fuse 14 in the underhood fuse block. Fuse 14 gets it power through the fuel pump relay which is activated by the PCM.

The 97 and 98 diagrams show the same power flow. I suggest you see if the relay is working and if not, check for input from the PCM. The PCM supplies a ground signal to the Fuel Pump Relay. Check the FP Relay for +12v and a ground. You can also have someone turn the key while you are touching the relay to "feel" if its working. If the relay is working check for +12v in and out of the relay.

Did you forget the PCM ground wire at the connector? Weird things happen when that's left disconnected.

Nope that ones good... I made sure to double check that one though. I will check the relay next, I tried at least 3 of them in there, but obviosly if they are not getting power then its not going to do a Dang thing. Just wish I had more time to diagnose this thing, thanks for the help so far guys!

How's the wire insulation under the power distribution box? Are there little red flakes everywhere? If the insulation is gone the wires will short to the frame.

If you got the computer and such from a car with an automatic, and put it in a car with a standard, that could be your problem. Mixing years and types of trannies aren't something the computers like.

Luke the wires were Flaked but only up by the battery, I will double check down lower.

The harnesses should be from a '97 and from a manual tranny car, too. Even a model year can make a difference.

I know this exact swap has been done before. In fact it was by Spridget above. 97 computer with a 98 atx harness. These cars have major issues with the insulation on the wiring harnesses flaking off. This 98 harness is far better than my 97 harness was. Now if I can find which pin from the Pcm signals the relay I should easily be able to do a continuity test on the harness itself, and also make sure its not shorted to the body or another wire in the harness.

Looks like Pin 80 on the PCM supplies ground the FP relay on both the 97 and 98.

You are correct about model year differences. There were many revisions to the Contiques during production. However, I performed a similar swap a few years ago in my '97 MTX using a later ATX harness. The only difference was some extra connectors for the transmission. The rest of the pinouts from thethe PCM were the same. My '97 sufferred from the dreaded flaky insulation too. I had to replace almost every wire under the hood.

Chris, check the big 3 connectors next to the PCM if you haven't already. They can be difficult to fully seat. I don't think that would cause this issue though.
