Sorry, been off line for a couple of days.

Do you still have the problem? A test light doesn't really tell you what you need. You need a DMM and a knowledgeable "wire nut".

Yes, there is only one main fuse for the P/M motor. It's 30A in the fuse block under the dash. The 2 middle pins on the motor plug (B & C) are from the ignition switch and the battery, respectively. Pin A grounds the motor, pin D grounds the relay through the switch.

If your motor isn't running at all, you could have a ground problem. Simple to fix with a little cleaning or posible relocation of a traced wire.

If you motor is "clicking" every few moments, it would be a symptom of a blown accumulator ball. The pump would be deadheading. Turn on your key without starting the motor and listen under the hood. You may hear it click every once in a while.

Aren't you the fellow I helped a little while back with the P/M I told you was bad from SE Turbo? Strange...3 in a row being bad? Where are they getting them from, the boneyard? Homemade rebuild?

Read my response to help diagnos a brake problem . Maybe its not your PM that is bad . Your whole brake system has to workk right for your pm to function properly .
