Ignore the coils

You need to fix your trigger issue.

No RPM. No nothing.

If tooth logger shows nothing then you obviously won't get RPM.

Pull the Speeduino and feed it 12v out of the car.

Check the 5V there

Ignore the car until you can fix whatever is wrong.

Also you really should be providing your tune.

Is it the base tune supplied with firmware that you modified?

Finally able to test again today, trigger logger shows nothing. I have the igniter setting at 12v and I have the original Jeep 4.0 coil connected.

Duralast C932 Coil

Isn't that a dumb coil? What ignitor/driver are you using to fire them?

Yes, I'm sorry, forgot to mention, it is the base tune, didn't want to mess with it at all until it at least tries to fire up.

Update!! I do have 5V !

I purchased a new multimeter and turned out to be defective...so replaced that one too and now I'm able to accurately say my 5V outputs are working correctly

Did you try a new battery in the old multimeter, they do strange things when battery is almost empty.
