Cranks, but no start
 

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!!

RE: Cranks, but no start
 

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.

RE: Cranks, but no start
 

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

RE: Cranks, 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.

RE: Cranks, but no start
 

No bounce upon start.
