Check the distributor cap and rotor, dude.

Cheers.

check about ignition control unit (module). Since you said- no spark. I don't think that cause by ignition coil, cap, rotor or wire.

Ignition coil, cap, rotor or wire will cause weak spark, but those things still get spark on. If absolutely, no spark----- most comment thing is ignition control unit.

One more thing, does your starter turning???

Try this thread:


300E no spark continues.
