Need some help here. My sister parked her 88LS into her garage and now it wont start. Engine turns over but will not start. You can hear the fuel pump come on. After cranking for awhile you can smell gas from the exhaust. Checked for fuel at the fuel filter, and there was when the ignition key was turned on. I checked for spark at the spark plug and there was a spark. The check-out with an ohm meter on the ignition coil was good. Put a new ignitor on , still no start. Checked the timing belt and it looks good.

Read about the main relay that could also be a problem on other threads.
Could this main relay also be the problem on this 88LS too? And where would it be located on this car.

Any help much appreciated!
