I bought my car 84 Euro 500SL, knowing it needed a little lovin. I've now put the THIRD ignition module box.(yes the box screwed down to the inner drivers side fender) Granted the two ignition boxes I replaced my original with were used. But they worked!!! A couple days after the car was running, (Good, but not great) It dies on me and will not start again. No Spark, no power to the distributor/coil Nothing. It turns over and smells like gas. Replaced the ignition box twice. Car started right up.

After just getting my car towed after dying the THIRD time. I'm starting to think something else is the cause of the problem. What could make my ignition module box go bad so often??? I'm clueless!!
Thank You.

Chase, it's important that all the ignition components (distributor cap, distributor rotor, ignition wires and coil) are in good condition. I'd check/replace those before installing another ignition control module.

Ditto!!!!

Coil, coil wire, & cap/rotor are the common causes of module failure.

apparently there is a special dialectric paste that must be applied to the back of the ezl module or it will short out.very important.i recommend a search for more details

That dielectric grease doesn't apply to the 1984 models....

Thanks Guys, We've checked the cap and rotor, they are both damn near brand new. I guess replacing the coil and coil wire wouldn't hurt. It just seems like theres something more major wrong with the car. I'm picking up a brand new (for the first time) ignition module, the 3rd party (smaller and flat one) I'll double check the ignition pieces and we'll go from there.

Thanks again!!
