Due to my lack of available, accurate information,the ideas everyone sent in proved to be extremely helpfull. The problem did end up being a bad solder joint in the ecu.It was caused by a small intermitent short to ground in the circuit running from the hall effect in the distributor to the ecu.It just barely rubbed through the insulation(like one strand of copper touching the body)under the vehicle where the harness goes into the passenger compartment to the ecu.Found it by pulling the harness out of the grommet so I could get a good visual look at it. It appeared that hte harness was not in it's original position which put extra strain on it.Rerouted it when I put it back in. Again,,,THANKS!!!!!!!!!!! ____________________ ORIGINAL MESSAGE: _____________________ Towed this vehicle to my shop with no start,quit on the road. Check for spark--no spark--no fuel pump operation--no injector pulse. Following manual--checked for power at hall effect device on blk/red wire--no power,according to my manual the hall effect gets it's power directly from ecu.Checked for 5 volt reference at tps and cts--no reference. I have very limited experience on V.W.'s as there are not very many of them in my area,so, I also have limited information. Any ideas would be appreciated. Thanks in advance!!!!!!!
