2005 V8 won't start. I've had the Kessy rebuilt with new mosfets and transistors. The vehicle has q fully charged battery and there's power to everything. I can also remove it from park. I'll upload the VAG report when I get some replies to this thread.
Any ideas on what could be causing this?
From reading the forums I thought it was the Kessy but to no avail.

Full autoscan, please!! :- )

Have you tried starting it with the key in the ignition switch, too? (I'm sure you did, but just covering all the bases.)

 

[schossow5]

Yes, it doesn't have the push start, only key.
I'll upload the scan when I get to my computer.

Look under the left and right front engine covers and verify the timing belt is fine.Take 2 minutes a side.

Next, have a battery charger connected while doing all testing/checking. You are getting a lot of under voltage errors.

I would then clear all codes and re-run the scan (and save the scan).

I would then try to start it and re-run the scan (and save the scan).

After that, it depends on the scans.

If I got a lot of random errors, I would be looking at the wiring harness as we have a established problem in some cars.

If I got a pretty clean scan, I would start looking at the (CPS) Crankcase Position Sensor.
