So I just recently got my 2.3 turbo running in my mustang. I have been driving it for the past few weeks trying to work out the bugs, which there are MANY. But last weekend after letting the car sit overnight, it would not start in the morning. After looking into it more, I found that there was no spark. I went through the ignition system and found that the coil is no longer being grounded. I have 12v to the positive side of the coil but no continuity to ground on the negative side, even when cranking. I tested the ignition module which seems to be good. My last thought is that the ECU went bad somehow. How can i check the ECU to ensure that it is still functional?

You could always run a KOEO trouble codes test....You’ll need a OBD1 code reader..

I still have yet to get an OBD1 reader. Also doesnt help that the connector was removed from the harness that came with my ecu and motor.

If it won't output codes it's dead. Other way is to pull the case apart and look for burnt/damaged components inside.

I put the OBD1 Port in this weekend. Checked for codes and got the normal engine swap codes for some missing sensors. Looked more into the coil which tested good. I pulled the distributor and checked the TFI module out, the TFI module passed all of the tests that i found on rothfam. I noticed that the hall sender is getting hit by one of the blades of the trigger wheel. The hall sender is also not outputting any signal. I am almost certain that this is my issue. I have ordered a new Hall Sender to try next weekend.
I ran through the entire svonostart pdf on rothfam, everything tested good except no signal to ground the coil.
Anyone else have any other ideas?

I'd say you're on the right track with the trigger wheel issues. Lets see what it does once that's fixed and not dragging.

Well I got it fixed. It was the PIP. I replaced it with a new Motorcraft PIP and straightened the vanes on the trigger wheel. After putting the distributor back in, it fired right up.
