83 n/a no spark
Hello, I have a 1983 944 N/a with no spark, I have checked Dme relay. Possibly alarm module? How do you jump the alarm system? and also dme has some corrosion is it possible the main DME not the relay has gone bad? would that lead to no spark?

Whoa! newbie alert
Hey buddy, lots of DME info here, just search the forum for it. Also check out Clarks Garage, good info there as well. There are current flow diagrams for your car on this website. IMHO, check them out and trace the circuit power one way or the other. Check power to the coil and DME Relay. It doesn't hurt to clean the fuses and check the grounds. There is a real PITA ground at the bell housing. follow the ground from the battery to where it disappears behind the engine.
For no spark conditions it is a good idea to go over connections as well. I suggest checking the speed and ref sensor connections as they go a lot and will cause intermittent or no spark. Viel Gluk.

Electrical may be a PITA, but it is not overly complicated. Like SolReaver says, go through your connections. A $20 multimeter and a wiring diagram are all you need, the rest is just time and effort. Almost as simple as paint, and less of an art form.

post you're info in you signature helps out alot. History of the car would help like. " I just bought the car and it has no spark" or " all of a sudden i don't have spark anymore
"

I say electrical on a car is PITA lol. Much harder than a motorcycle where all I have to do is remove the tank and seat. But still not complicated, just chasing wires.
