OK, if anyone remembers, i was replacing the harness and computer in my m50tu. I finally got the right computer and the right harness. The fuel pump works, the starter cranks and there is spark from the coils. But the car does not start after being cranked repeatedly. It just kind of makes a soft thump noise.
Now it has been suggested that the ignition timing is wrong because the crankshaft pulley is different on vanos and non vanos engines. You know the thing that the camshaft position sensor is near. The parts numbers on OEM are different too, but after going to the junkyard, the grooves on both pulley look exactly the same.
So the question is, will the crankshaft pulley be responsible for the car not starting and will putting another one on solve this? If not, what else could affect the ignition timing, given that the car ran fine with the nonvanos harness and computer before?
