I’ve searched through the forum for all matters similar to my situation. I haven’t found a match, however there has been a common denominator in many of the posts. It has been the “Ignition Coil”.

In my situation, I’ve noticed that my 1989 300E will not start on rainy or damp days. When I turn the ignition to start the car, it does crank but will not turn over. If I’m diligent enough, I will get the engine started after 5 minutes or so (at the risk of burning out my starter), but the engine will rev high then low intermittently. After allowing the car to run idle for 5-10 minutes, I’ll try driving away only to have the car stall on me (mostly at a red light). Then it can take 5-15 minutes to get the engine started again.

The history of problems fixed/replaced with new parts on my car is as follows (latest to oldest): replaced fuel pump relay; water pump; OVP; and alternator.

I am now requesting from all of you on this forum to help me diagnose this problem or confirm if my next step of replacing the “Ignition Coil” is a correct one. I am extremely frustrated with this and for the first time considering getting rid of my love of so many years.

On another note, I have researched pricing of the Ignition Coil and have compared the photos on Fastlane and AllPartsExpress of the one mounted on my car and I am a little baffled about the mounting method. If it turns out that the Ignition Coil is the culprit, will I have to change the mounting of the unit when I order a new one. My current one appears to be strapped in. I am attaching a photo of the Ignition Coil currently installed in my vehicle.

Thanks to everyone in advance for all of your guidance, comments, and opinions regarding my case.
