I check cylinder compression and fuel pressure. all were OK. I have concluded cyl #3 coil is not getting a pulse.

I need to check for continuity to eliminate the harness as suggested, I need to find out the best way to do that?


Thanks for the help Guys.

You need to disconnect the coil & the DME. Then using a pinout diagram of the wiring harness check each wire individually from the coil to the DME. Obviously you need a meter that is functioning properly or this time will be wasted. Example, touching the probes together should NOT give a reading of -.2. If all that checks ok, I’d vote on a bad DME
