my 1994 pontiac grand am 2.3 liter starts and runs fine for about 10 miles, then quits/stalls. come back in a couple hours and it will start and run fine for about another 10 miles and stall again. It will not start unless you wait till it cools. fuel system is fine. how can i check the ignition control module and coil packs? if one coil pack is bad will the other still fire 2 cylinders? i am on a tight budget and these parts are expensive. i have already replaced the fuel pump, filter, and fuel pump relay. (for nothing), please help?

ITS MOST LIKELY BAD COIL PACKS, REPLACE THE COILS. THEY GO BAD AFTER 50-60K. YOU CAN TAKE THEM TO AUTO ZONE WHERE THEY CAN DO A RESISTANCE TEST ON THEM, HOWEVER IF THEY HAVE BEEN ON THERE FOR AWHILE THEN ITS TIME TO REPLACE THEM WITH NEW COILS.

I have since fixed the problem,(6 months ago). It was not the coil packs or ignition module as many have told me was the problem. The car has 150,000 miles and the coil packs are fine, I have the newly purchased ones as spares now. It was the crankshaft position sensor. It would fail when the enginge got hot and the car would shut off. Be careful removing the old one since it is plastic and brittle and could break off flush leaving a piece to fall inside the crankcase.
