First you have to determine what's missing, fuel pressure, spark, or both. Next you have to list the engine size when asking about an engine problem. If you have a crankshaft position sensor in the top of the transmission bell housing behind the right cylinder head, that is a common failure item when it gets hot, and it will often work again when it cools down. Usually though it takes a half hour or more to cool down. Check for voltage at the ignition coil's positive terminal during cranking. If you find 12 volts there, you have either a spark OR a fuel supply problem. If you find 0 volts during cranking, you won't have spark or fuel pressure because the Engine Computer isn't turning on the automatic shutdown (ASD) relay. That's due to a failure of the crankshaft position sensor, or the camshaft position sensor in the distributor. Reading the diagnostic fault codes may indicate which one has failed.
