      I've tried with a different Ecu. Same unitied (c2) EPROM. I can see the chip taking a
      Crap maybe messing with the power cut up top, but to make it not start ?
      Btw Thanks for responding !

      So at this point you aren't getting spark or fuel at all?

      Alarm immobilizer?
      Clutch switch?
      Another Ign switch?

      Basically, judging by the fact that you aren't getting either, I'm guessing your electrical set up is seriously boned, or something in place by VW meant to cause a no start, although I honestly don't know if they cut fuel / spark or prevent the starter from cranking.

      Maybe it is the chip, I feel like a chip would be adjusting the fuel and spark signals from the ECU, so it it fried, it could be sending no signals at all.

      Yes there is no fuel or spark. The Car cranks pretty good. All the interior electronics work lights, radio,gauges ect. I have another chip laying around with a 42lb injector /turbo map on it. Goin to throw it in next time in off and see what happens. Thanks

      Did you replace your Fuel pump relay with VW or aftermarket japanese crap, same with Speed Sensor aka (Crank sensor) ?? I've heard stories our cars don't like these "Aftermarket" replacements you can get from chain parts stores also more of a chance of getting a faulty item fom them. I'll keep you updated

      BTW...could also be the Fuel pump !! ??

      Yes the crank sensor was the first thing I changed cause no fuel or spark are usually the symptoms of a bad cps. Also replaced the fuel pump relay. Both oem Vw parts. I am currently running 2 fuel pumps one stock one 255 in line pump. They both run fine. If you havent checked you're fuel pump yet ,what I did was run a wire from the positive side of the battery to a switch straight back to power wire of the fuel pump. I have a wire diagram on here some where I will look it up for you.

      Thanks for the help

      That would be GREAT to have...
      Like I said I will do the CPS (again) and the relay then go from there. It will be a couple days before I can get to one of my shops I use where the car is to get after it but I'm sure between the two of us and maybe a helpful hint from someone else we can get these DUB's back on the road. This car was my first MKIII I ever owned and didn't do any "modding" only normal maint and a couple small add-ons and flipped it but she stayed in the family so to speak and I refuse to let it die...
