Thank You so much! This has been a nightmare to diagnose especially with out a good diagram. This car has been sitting for a year. Just got it in. Had been a no start and went to another shop that put in a fuel pump.
I've got it now. The first thing I did was go to the relay. Relay has a constant + going to it. I figured The PMC was controlling the relay with a negative. This diagram confirms that. I am a little concerned that I activated the relay manually with no activity from the fuel pump. I used a UACTIVATE from aeswave.com and also hooked a low amp probe at the relay with no results. I think I am looking at multiple problems here. Thanks again for the diagram.
Check fuse 14. When you activate the relay, does fuse 14 have battery voltage on BOTH test contacts? If it does, check/reset the inertia switch. Finally, check the Fuel pump ground.

I did check fuse 14 and it was good. Inertia switch was where I was going next. The only problem that I have at this point is I don't have the violet/orange wire on the fuel pump as described in the wiring diagram. Any ideas?
What colors DO you have at the Fuel pump? What colors at the inertia switch?

Not in the shop now so bear with me. I know the one's I were assuming were the power and ground to the pump was a brown/green wire and a white and blue. There is also what looks like a fuel pump module in the trunk. I haven't checked for the inertia switch yet. That will be first thing in the morning.

Thanks, pole71! I was trying to dig up that same diagram, too. BBB Industries doesn't seem to have it.
Dave101, I'd suggest checking voltage at the white/black and brown/yellow wires at the module during cranking. These are the pump power and ground provided by the module. OR, you can check the green/orange and black wires for voltage during cranking. These are the module power and ground.
Either check will help point you in the right direction.

Thank You both for the information. It would have taken a lot longer to figure out what was wrong with this without your help. Just for my knowledge, what was the difference in the two diagrams?
No problem! I think pole71 probably noticed the same way I did that your module connector had six wires, which means it's a Fuel Pump Driver Module setup. That first diagram had a conventional relay circuit with no module involved.

Early or Late production. The First diagram was Early production. You, apparently, have Late production. Sometime in the production of '99 Contour, they added the module.

Guys thank you so much for the support and wiring diagram. This car had a broken ground going to the fuel module. It would have taken forever to fix if had not had a diagram. Thanks again.
Glad to hear it's fixed!
