I'm having a bit of an issue with my ignition and was hoping someone could give me a push in the right direction.
96XJ 4.0 has been acting up with stumbling throughout the rpm range, especially on load. Driving it gives me quite a jolt.
Been testing a bunch of snesors, fuel pressure, compression and so on to no avail. Tonight I got to the coil.
While performing test Test 4 here: http://troubleshootmyvehicle.com/jeep/4.0L/how-to-test-the-ignition-coil-3
Turns out I don't seem to have an ignition driver pulse. Rather it's a comstant 12V no matter if the ignition is on or not.
This would indicate a short somewhere right? But howcome the engine manages to run albeit poorly and without power?
What am I missing?
Not terribly good with electrics. Funny that since 90% of the problems I'm having are just that but it doesn't seem I'm getting any better at solving them.
