Ok I have a B7 with an A6 head and y8 cam gear I finished putting it together and got it running this morning. So i let it run for 20 min or so and drove around the block...It felt like the timing was off a little bit so as I was pulling in the driveway it stalled out and would not start back up. I first tried adjusting the distributor than took off the timing belt bought it back to tdc and tried again over and over still nothing. I have good spark to all 4 cylinders and good pressure to the fuel rail. No check engine light. I checked the firing order just to make sure everything looks good I dont understand why it wont run... Any suggestions would be appreciated.
