94 ENGINE HESITATES AND ONCE IT'S DROVE SO IT WARMS UP THE CAR WILL NOT START UNTIL IT COMPLETELY COOLS DOWN. COULD IT BE FUEL FILTER OR RELAY OR FUSES?

1994 Lincoln Mark VIII • 115,000 miles

Engine hesitates and after the engine warms up and car drove some it won't start until car cools all the way down again. Could this be the fuel filter, relay, or fuses?

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 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, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-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,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
