Thanks for any help. I have a 1983 Buick Regal 3.8L V6 Base Model Coupe. A few different problems or going on at once with the car and could all be linked in some way but at this point im not sure. To simplify things the major issue is No start. I recently replaced the starter and alternator to I was checking wires and noticed the charge post moves just a bit to one side or the other. Could this be my problem? Also recently changed coolant and drove the car. It ran fine but service engine light was on. Put it up and tried to start it and it just cranked but no start. There seems to be crank and spark from plug. Distributor is getting power. Carburetor's getting fuel. The other issue is my accelerator pedal and the idle speed control under the hood keep pulsing (like feedback or tapping just a little hard to describe) when out of park. Thanks for any information on this, just kind of lost at this point. Thanks again
