[Cavalier9696]

I recently sold my 96 cavalier 2.2L to a buddy of mine. The thing is, he let it sit up for about 2 months (which told him thats not good for a car). Now it wont crank. It will try and turn over but wont. He said he was driving down the road and all the cluster lights came on. Like the check engine, water etc. That was about 3 days ago. When he was drivning home the car backfired and now it wont crank.

Plus before all this happen he said he was jumping it off and he hooked the jump cables up wrong on the car which made the starter smoke real bad. Could that be one of the problems?
Thanx.
