I have replaced the alternator, fuel pump relay,plugs are new and so is the battery. I have checked the coil too, good spark. The tach does not bounce on starting. So either Computer, reference sensor, or speed sensor? What does everyone think? I was driving it...shut it off, never started again. I have a 2100 mile trip to take in this 83 944...help me!!

 

Check your speed and reference sensors both

 

I had that problem, mine turned out to be the computer. somehow some water worked its way into it through the battery area, dripped in, and shorted it out.

 

Well I ordered both sensors from a Porsche place in Phoenix, Az. Hopefully have them by saturday and I will install them right away. If this doesn't work, all thats left is the computer....right? I will keep you posted on any progress.

 

what parts did you order and from where? (part numbers) because my 944 is doing the same thing, turns over but no start

 

Check the tac bounce before you order those, if the tac does bounce when you crank the engine its not the sensors.

 

No bounce upon start.

 

tach does not bounce....what parts do i need?
