Last night i was driving my car with no issues, parked it for 45 minutes after a game of putt-putt golf and it wont start. Prior to this i have had no issues with the car whatsoever. Flashed the car back to stock to ensure it wasn't tune related, but i am getting the following codes still with no start:

P3100 - No Cobb description, but I believe this is a generic code for a limp mode event
P2A9A - Crankshaft - inlet camshaft, correlation
P2A9B - Crankshaft- exhaust camshaft, correlation
P2ACB - DME main relay control
P2ACC - DME main relay, diagnosis for a condition shutdown test
P2A9E - Intake camshaft, synchronization
P2A9F - Outlet camshaft, synchronization

So basically at this point i had the car towed to my house and i am going through the fuse box behind the glovebox and will check the fuses in the DME next. Anyone seen these codes or have these issues before?

Fixed, main relay was either loose or going bad. Gonna pick up a spare just in case.

Good for you!

Was that relay located on the fuse panel behind the glove box?

Yes it's on the right side of the fuse box behind the glove box. Noticed it was very warm when I put my hand near it. Took it off and inspected it, reinstalled, car fired right up.

If you continue to have problems, you may need to check out for corrosion at the junction box on the main power cable that goes to the battery. It is in the same location and exhibits the same symptoms. You may have just got lucky with jiggling the relay. There is an SIB out on the cable/Junction box.

I actually replaced the fuse box and cable about a month ago. I am unsure if I left the relay loose while transferring to the new board or if the relay is actually going bad.
