Start with checking the plugs. I've seen a few loose wires in plugs.

Everything seems tight Dan. I will open the harness and start checking each wire. What do you call this unit? Just saying master brake cylinder just shows me the standard one, not this thing that is on mine. Is it still called a master cylinder or will it have a different name?

You talking about the ABS module? That'* the part with all the brake lines going in to it.

No, the whole unit where the standard master cylinder is. Mine is all electric or hydrolic. Is it still called the "master cylinder?"

Ahh, the big round thing on the fire wall? The master cylinder is what sticks out of that. The round part is the power brake booster.

Ok, were not on the same page. My car is one that does NOT have a power brake booster.

This particular car has the Teves ABS, which was no longer used from 91(could be 92) on. I am not too familiar with how these work, but I recall a common failure point is the accumulator, which is the black canister looking thing on the top. What happens when that fails is that when you hit the brake pedal, you will be faced with a rock hard pedal, and the pedal will move down, and braking will increase as the pedal moves down. While this is happening, the brake and ABS lights will come on, while the pump is running (at the same time the pedal is going down). If you pump your brakes repeatedly, you may be able to replicate the symptoms.

These units are prohibitively expensive to service, and when they fail, many usually either grab junkyard units (crapshoot) or grab a non-ABS master cylinder/booster assembly and cut their losses

Ahh, that explains it. Not a system I have ever worked on.

Default Lots of pictures

In the 1st picture you can see what I am working with. The 2nd picture has 2 circles. The bottom one is about where the pump/motor is and the top is some kind of relay. I have it down to the relay is bad now. Sometimes it will click and the pump turns on. When it won't click to turn on the pump I lose the rear brakes. Can ANYONE tell me what that relay is called and maybe where I can find one? The other pictures are just of the car, this is why I want to save it.
