i copied this from another post i posted.
i had the same issue with my truck. the ground wire came disconnected and i dont really know how it happened...basically i cut the ground wire at the coil and grounded it to the body.
this is how i tested my coil for power.
if hooked up properly you can use a test light and check the power running into the ignition. you cant use a test light to test the coil wires you need a special tester for it but while the ignition in off hook the test light to the positive on the batter and test both wires. both should light up. turn the ignition on and test the same two wire...only one should light up. as for the other one that didnt, ground the tester and try that one...it should then light up if all done correctly. if power is goign to the ignition then it should be getting spark, as its very unlikely for one wire to go bad, let alone all four.
