Mercedes Benz repair: Mercedes 300TE Doesnt Start When Hot, mercedes 300te, engine wiring harness


Question
1991 Mercedes 300TE Wagon

Yes, it does start cold just fine. However after having a run, and parking it, it won't start. It will turn over but it doesn't feel like fuel is being injected or it's just not sparking. Last night I drove it for 5 minutes and parked for an hour and it did the same thing.

The past times it has done this have been in wet weather, and once, it half died on the run clunking its way back home, like not enough gas was getting through. But it WILL start after a few hours, so it seems heat is an issue. And then sometimes it just starts fine.

Coil have been replaced on it, but it hasn't had many repairs otherwise.

Many thanks for any thoughts you might have!
