2001 ZX2 Fuel pump relay

Boccemon · 07-01-2009, 01:57 PM

I've been pulling my hair out trying to get my sister in laws' 2001 Ford Escort ZX2 running. A "mechanic" told her it needed a fuel pump after it quit running, and she had him put one in. The car still does not run and the "mechanic" more or less just threw his hands up. All fuses are good. I understand from a Ford garage that this car has a Constant Control Relay Module in it which is not servicable, and that it contains the FPR. How do I check this unit to be sure it is bad? They want a hefty price for a new one and she has already paid a pretty penny for the fuel pump.

When the key is on there is no activity at all in the fuel pump. Any ideas or instruction?

Thank you very much in advance, BocceMon

There is a fuel pump inertia switch, that when tripped, removes all power from the fuel pump. The switch on the 2001 is located behind a small round cover below the interior fuse box on the driver side. After you remove the cover, you will see a small red button. Push it down, if you feel it move down or click, then the switch was tripped, if you don't feel it click, then it was fine. The CCRM is serviceable if you are comfortable with soldering. Although, it could also be the fuel pump driver module or any number of the wires that carry power and signals to the fuel system.

Thank you for your reply. I noticed that round cover yesterday, removed it, and lo and behold, I could find no switch. I'll have to look further. All that was behind the cover was some wiring.

I found the switch upon looking again (it's way down there), but no joy. Upon inspecting the CCRM, without taking it out, it appears to have corrosion on it from the battery directly above it. This might have a detrimental effect on the CCRM, would it not? I'm going to remove it tomorrow as I have 4 days off. How do I field test the CCRM to determine if that is the problem?

I am not comfortable with soldering;however, my IT guy here at work does it all of the time. He tells me if I get the right part that he can do it. I read about servicing the A/Cair conditioning relay in the CCRM in the ZX2 forum. Any idea what part I need and where can I get it? Radio Shack? What relay??

I think all of the relays are the same. I know the A/C one can be bought at Radio Shack. The cover on the CCRM is riveted on, just drill the rivets out and look for a burnt relay. You could always remove the kick panel over the inertia switch and check the wires for voltage with the key on.

Before you do all of that, the corrosion can cause a bad connection, which will cause all sorts of strange electrical issues. The ground for the CCRM is actually in the wires on that little black box attached to the negitive cable. Remove the cables and use a wire brush (they make one for this purpose that can be bought at most any retail store) and clean them really good. Put the terminals back on and see if that fixes your issue.
