FORD TEMPO SPARK PROBLEM

1992 Ford Tempo

Engine Performance problem
1992 Ford Tempo 4 cyl Front Wheel Drive Manual

started out with the car sputtering like not getting fuel. Changed fuel filter didn't help changed mas air flow sensor starts and runs fine until you shut it off then it won't start again until you let it sit for about an hour. But you can drive it and let it get warm and everthing runs fine but if you shut it off you have to wait to restart

Next time it happens, don't wait for nothing-do below immediately to determine whether it's fuel or spark issue: Cranks but no start condition: Fuel and Spark: Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
