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.

RE: Cranks, but no start
 

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.

RE: Cranks, but no start
 

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

RE: Cranks, but no start
 

I'm getting my parts from a place in Phoenix Az. called ..........

RE: Cranks, but no start
 

thanks man, i hope thats it...its expensive freakin car

RE: Cranks, but no start
 

I cannot remove the timing sensor. Its loose, turns freely and I have it pulled up about an 1/4 inch, yet it will not come out. I even sprayed it with WD-40. Amy suggestions?

RE: Cranks, but no start
 

I've replaced the sensors and my car is finally running!! Thank you so much to everyone that helped and gave advice. I'm truly thankful.:)

RE: Cranks, but no start
 

I'm having trouble finding the timing sensors... do i need to get two?

RE: Cranks, but no start
 

You need to establish which of the two sensors is bad. You dont need to replace both, but it sure wouldnt hurt.

RE: Cranks, but no start
 

ok, but I dont have a book... How do I find these sensors?

RE: Cranks, but no start
 

One sensor is located at the top of the bell housing at the back of the engine over the flywheel, the other is on the back of the cam pully on the front of the engine.

RE: Cranks, but no start
 

That reply may or may not be correct. Drummer and I both have a 1983 944...both of my sensors were together...down below the oil cap, on top of the bell housing.

RE: Cranks, but no start
 

Go to http://www.clarks-garage.com/, and look at the shop manual, [align=center]IGN-02, Speed and Reference Sensors - Checking, Replacement, and Adjustment[/align][align=center][/align][align=left]This will show that both sensors are on top of the bell housing and give you the info on repacing them. there is also a trouble shooting section that may help.[/align]

Forgive me I was thinking of the later spec.
