The next day i started the car it would only make power to 4200 rpms fall on its face then start to make power at 5800 rpms. at the moment there is no spark or fuel.

9.replaced half of the engine harness.(injectors, throttle body,dist ect)
10. starter cranks hard
11. replaced hal sensor

13.compression 150 across the board
some one please give me a hand i am running out of options and getting very irritated. at this point i want to burn the car to the ground lol. any suggestions,ideas,experiences would be great
thank you - jay
So at this point you aren't getting spark or fuel at all?
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.

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 !! ??
Thanks for the help
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...
