When I try to start the car it backfires and the starter motor disengages, therefore the car won't start.
The key guy said that the 1990 Chev Cavaliers key assembly was not electrical. Long ago he put graphite and that seemed to work. But recently, not even graphite worked. He said it was not the key mechanism and suggested it might be the battery. I had the battery checked and the battery was good. The parts place guy said that it may be the starter. Does somebody know the correct answer? If you let the car set for a while...such as will start. But if you drive a while then turn the engine may or may not start. The key turns and you can hear other electrical stuff, fans turn on....but the car won't crank.
which gas line feeds the carborator
I have a 2.2 i was driving and the postive wire on the start moved and hit the other wires on the start.It wrecked the starter. I put in the new starter. The car turns over now. I have fuel to the intake. If I put fuel in the intake it will run for a few seconds and then dies. Could one the sensors be bad on the intake be bad?
