1993 automatic Del Sol Si
Ran fine when purchased. Let it sit 2-3 mo; wouldn't start.
Installed new battery; ran fine again. Stored car for 18-20
months. Car wouldn't start. Placed trickle charger on
battery. It starts but as soon as it turns over, it dies. ???
Are you trying to start it with the gas that has been in the vehicle for 18 - 20 months ? If so that is your problem.
