Ok, so a buddy of mine bought a front end wrecked 01 Passat with a V6 from an auction. We rebuilt the front end...mostly cosmetic damage. Have no idea the running history of the car before we bought it.
It will start and run great, then out of the blue shut down and won't start again unless we pull the plug for the MAF or fuse #34. Once we pull either of these, it starts right up and runs. If we immediately try plugging either back in, the car shuts off, but if we leave it running for a min or two and plug either back in, it will continue to run for an unspecified amount of time before it dies again. After dying, it throws many codes indicating many different sensors "shorted" or circuits open or low.
If we start the car with the MAF unplugged, it runs great but throws a code for the MAF being unplugged...obviously. If I plug the MAF back in it will run fine for a good long time...long enough to drive at least 5 miles or so. BUT, if I clear the MAF code, the car will immediately die. I have already replaced the MAF with a known good one...same results. It also doesn't make sense to either of us we can pull fuse #34 and the car runs great...but throws a ton of codes.
We're stumped. Need your expert help on this one!! We're about to douse it in gas and have a bon fire...
Thanks!
