Ignition Coil Troubleshooting

[cfl_cherokee]

Got a 96 cherokee 4.0l a couple months back that doesn't have spark. Been through the usual suspects (CPS, NSS, ASD, Fuses). I have already had to repair some wiring due to rat damage but have fixed everything I can see. I've replaced the CPS and ignition coil with MOPAR parts that pass the resistance bench tests. I'm wondering if anyone could put a volt meter to the plug going in to the ignition coil and let me know what voltages the two lines get. I'm currently getting 9.97v through the green/orange and 11.54v to the black/grey. Thanks in advance

Current to the coil would be 12V

Any idea what the switching signal is from the computer?

Switching signal is from the cam position sensor in the dizzy

The dizzy?

Distributor It does go round and round inside.

I swapped out the dizzy and cam sensor from my buddy's jeep. No change.

How did you determine you are not getting spark?

[cfl_cherokee]

I have an inline spark tester and I tried the old fashioned, hold the plug on the block and have some crank

Take the coil wire off the distributor and hold it to the block and crank

I'll give that a shot tonight, thanks for the tip
