Question 944 Does Not Startii

Are DME and DME RELAY the same unit.
Where is the location of the DME relay
Which is the secuence of the timing sensors, wich wire with which sensor
Can recomend a good source or publication for parts number and/or simple electric diagram with details or info?

Have no experience with eletronic systems and the only reference manual at hand is the Haynes

This is my first 944 project, almost finish and now I am working in the electric area which is my weekest experience

Would be a big help if you said what year you are talking about.

that said, here are a few answers:

No, the DME relay and the DME are not the same. That said, the DME relay and the Fuel Pump relay ARE the same. If your car is an 83 - 85, the DME/Fuel Pump relay is seconf from left, top row.

in an 85+ it is the row closest to dirvers side fender, 2nd or 3rd from the rear.

In either case, the relay will say DME on it.

if your car is not cranking, try reversing the wires on the timing and ref sensors.

Haynes is a good start. Beyond that, there is the workshop manuals which include wiring diagrams

What issue are you having with your car?

It is a 1984,944
New fuel pump, new fuel-DME Relay
Refurbish DME
new coil, rotor and dist. cap and spark plugs
install used in good condition Sensors, the old ones had the plug desintegrate to time- dont know sensors sequence if any
Car was siting for almost 2 years
engine turns, but there is no spark
electric wiring complete but some contacts corroed by the time
need to check continuity( which is the only thing I know in the electric field) between coil and DME.
Any recomendations will be apreciated.

1st change your plug wires (it's not on the list of things you changed). If you have a multi meter, check your secondary side of the coil while someone turns the motor over. use the RPM funtion. If you have RPMs, then it's between your coil and your plugs. If you don't it's the other way.
