Hey folks...trying to track down a misfire issue with cylinder 4 and I want to try to test compression. Having never done it before, I'm having a hard time figuring out what I should be disabling in order to run it.

I've got the fuel pump fuse pulled, but am seeing mention of disconnecting the low voltage primary wires leading tot the coil or coil packs...I'm not seeing anything in that bundle of wires that has a disconnect? Could be I'm looking for the wrong thing I guess. Is there a fuse or relay I could pull instead? I've got the 2.0 engine.

Already put in new plugs and swapped around coil packs and the issue stays with cylinder 4.

Thanks

Joe

 

You are going to need to remove the plugs to run the check, If the injectors are unplugged fuel can't go in there.
