1992 ford explorer missing with new coilpack ,wires ,and spark plugs . has new heads ,new gaskets, new injectors, new o rings

Did you gap the plugs to correct setting? You may want to check the fuel filter and maybe the pump-maybe low fuel pressure.

Car sputters and no power, now it will not crank

Check the coil pack. they are common to fail and the engine will usually misfire for a while and then not start when it gets cold out. you can do a quick check by removing one plug wire at a time and having someone crank the engine. the spark should jump right down the tower the wire goes onto to the base of the coilpack. if this does not happen then you need to replace the coilpack first. take the 6 tork head screws out and remove the wiring under it that goes to the module. carefull not to mix up the wires under the coilpack or to the spark plugs. reinstall the coilpack and reinstall the plug wires and try to start the engine. i will look for a response incase you need more help. good luck.

Won't start turns over getting fuel and fire

make sure you are getting spark through the sparkplug wires. a sparkplug tester is the easiest way, or take a wire off one of the plugs try starting it and have another person watch the wire to see if a spark is coming off the wire to the sparkplugNOTE set the wire close to the sparkplug but leave a small gap between plug and wire so you can see the sparks. if not getting spark check all fuses first, otherwise the coil could be bad. or it could have coilpacks and one could be badNOTE every coilpack has two studs for wire, sometimes only one side of coilpack works if so it is bad both sides haft to work.

Why car will run then once shut off wont start again, at a later date it may start again and drive S IF NOTHIng is wrong. It will just spin a couple days later it may start again. checked gas-good also...

did u inspec condition of plug wires-they wear from heat etc-take that distributer cap off n I bet inside looks like dental decay--the ignition module is equal to the points and it fails-its under the cap n can be tested at a parts place

Car has a skip and not firing properly on all cylinders

Before you go checking parts that aren't there, unplug each coilpack connector one at a time with the engine running. After unplugging a coilpack you should hear the idle drop. If you unplug a connector and there is no change in idle, that is your problem cylinder. You can then check to see if there is spark by removing the coilpack and touching it to a ground on the engine, you'll hear it click. If you have spark, check the spark plug, if the spark plug is good, it's most likely a bad fuel injector. You can verify a bad injector by doing a resistance test after removing the connector. Injector replacement is a nightmare on these cars, but it can be done without pulling the plenum if you're mechanically inclined. Visit for more help.
