Today I took my car for MA state inspection. Enissions passed fine, but my backup lights don't work so the safety inspection failed. I'm going to look at the neutral safety switch under the car tomorrow. Drove home (2 mi) and my ASR and ABS lights came on. I turned engine on/ off a few times, and that didn't fix anything. I drove the car 75 miles and the lights stayed illuminated, but there was no other signs of anything wrong. When I got home the pump from the ABS hydraulic unit was running for at least 4 minutes and wouldn't shut off. I pulled the negative battery cable to stop it.

I just finished replacing the steering lock, ign. cylinder, due to a locked tumbler in '0' position. What should I start to look at/test and in what order. I would appreciate any help.
