Hey my 2000 f4 wont start and i cant figure out the problem. I have +12 volts at both terminals on the coil but there is no spark whats so ever coming from the spark plug. PLEASE HELP ME

 

. . .so replace the plug.

Is there something you're not telling us here?

 

There is no spark at any of the plugs !!!!!!!

 

Sorry, you only specified a singular plug in your initial post.

Where are you reading the 12v from? The end of the wire that plugs into the spark plug?

Where are you reading the 12v from? The end of the wire that plugs into the spark plug? Are you reading it while cranking, or just with the key on? Is th 12v solid, or pulsed? If it's solid, then your coil is most likely melted.

 

Bwaaaahahahah... you most certainly won't see 12v on the plug wire! And you won't ever see the pulse from the ICM to the coil, not with out an oscilliscope. Start by checking fuse "B". Check that there is +12v to the ICM on the black wire. Check the ICM is properly grounded. See if you find anything there. If not, you move onto the ignition pulse generator. Have a manual? Download one if you don't.

 

Ha. I was trying to be civil
