My Dad and I have two red 944's a 924 and a 944 parts car. Both 944's and the 924 crank over but wont fire. If all three seem to do the same thing we think it has to be the same issue or something. All battieries have been replaced and plugs checked for spark, and the fuel pumps are throwing gas so.... HELP Please! You'll be our hero.

Is the tach bouncing when you crank the cars? I am guessing no. If this is the case, check your DME relay, and the wiring at the speed and reference sensors.

 

For me it was the reference sensor itself, had to replace it.

 

Thanks for the help, we are looking into it. What does DME stand for?
