I have replaced the timing belt and water pump on my 2007 Passat TDI 125kw. I used a locking kit to set the timing gears in position and I am convinced that it had not shifted during replacement. I followed the factory instructions also. All I disconnected on the engine was the battery and the fuel lines through the filter.
Heres the rub though, after replacement I cannot get the thing to run properly.
I removed the filter cover to find it completely blackened. I replaced the filter, and still nothing. pulled the in tank lift pump assy to find the fuel in the tank was jet black. googled this and found the known issues with the tandem pump. purchased replacement pump from AFI, fitted and still it will not start.
This is what I have done up to this moment:
I tried using areo-start. we got it running but very rough and making smoke. it will not start normally though.
I have locked and unlocked the car before trying to start it
I can confirm fuel flow to the tandem pump out of the fuel filter.
I tried externally powering the lift pump.
I have pluggged in an OBDC reader, and there are no stored or pending DTC's.
Any further advice or hidden tricks ?
