I edited my last message. Unplug the small wire and measure that. Every time I've seen these starters fail, they don't even click so it's probably the solenoid failing. If you see +12v on that small wire after pressing start, your starter will be confirmed to be bad. Or jump the solenoid & if the starter doesn't activate, it's bad.

I jumped it like you said. I took a wire and went from the 12 supply under the hood and connected to the starter where the small wire attaches. The starter turned over when i did that. I thought the starter was bad so i removed it

:-/ First off, I'd replace the starter with a new one since it's out. They are known to fail and it's cheap enough to do preemptively. Since it did turn over, try to verify there is 12v on the small wire when the start button is pressed. You can test this with the engine torn down, just make sure the battery cable going to the starter is insulated & won't short out. If voltage is present on that small wire, there are only two possibilities - either a wiring fault (likely ground strap) causing a severe voltage drop to the starter or a bad starter. When starters go bad, they can often be coaxed back to life by tapping on them; removing it may have been enough for it start working again. I don't think it's a bad ground strap because unless it was really bad, it would click and then fail to turn the engine over.

If you don't see voltage on the small wire, I would highly recommend confirming communication with both the CAS & DME. Since the DME is returning codes, I assume it's fine. I don't know enough about the Foxwell scan tool to know if it can confirm an ECU is online or not. Most of the other issues that would keep it from starting *should* throw codes.

okay tomorrow i will check the small wire for 12v and im ordering a starter since like you said its already out

I'm with ARD on this one........breathlessly awaiting to hear what happened.

update: i installed the new starter. Still nothing....

Th wire that runs to the starter does not have 12v on it. What could this mean? I keep running scans and clearing codes but nothing is seeming to work. There are still a lot of electrical things that do not work. If i have to im going to post a video on line

I have to look up the electrical diagram to see which ECU signals the starter, but it means that you either have a break in that wire, a dead ECU, or a security authentication failure. I wish you had Rheingold / ISTA/D because it will show when an ECU is not online.

i posted a youtube video to show what is going on....

That video helps a lot. Trying to think of what this could be...


Can you check all the fuses that are in the box on top of the battery? Mostly interested in F172 & F173.
