No Spark Help
Have a 84 with 180 compression in all cylinders, have 12v to coil, not getting any spark to the plugs.
How do you check wires , it has fuel also. Tried new cool but results are the same. Car ran and sat for a year then this problem arose. Any ideas would be great. Thanks

I am guessing if you have 3 water-coolers you've probably seen this website before. Clark's Garage Home Page

Yeah this is 944 basic basics. Clark's Garage, DME relay, coil signal, tach bounce, loose distributor rotor, etc. You can ohm your spark plug leads but it is not likely they all failed at the same time.
12v to coil is good but the ground pulse is what sparks it.

Actually traced back to the DME, replaced it, started right up.
