Tach question for don
While cranking your car, does your tach needle move or does it stay seated?
If tach doesn't move, your crank position sensor may be disconnected or bad. Given that you just did the starter, look for the two connections for the two sensors. There are two 3 wire plugs and sockets located just forward of the washer fluid tank (basically, just above the starter). The two connections are detailed in the L-jet troubleshooting guide.
Your car does not have to start to check these things.
Don, can the car (s3) run with a bad crank position sensor? My car runs but I have never gotten my Tach to work. Not even a substitute Tach. Could this be my problem?
