I think the coil went bad on my jeep. I did the 'teamrush' upgrade to the f150 EFI coil. I've got power in to the coil (red) but don't seem to be getting power out. I tried gounding the spark plug and don't get anything, and tried grounding the coil wire and got nothing. I was wondering if there was anything else I could do to test it? or just spend the $40 for a new one and try it out??

thanks

sb

anyone???

uh get a haynes

might want to take it to a shop and spend the 60.00 for the dianonstic.. it might be other things ..
without a computer to test the system its hard to find some problems
