I purchased this car from a one-owner who had stored it in a heated storage building for years. I had it inspected by Mercedes, and completed several maintenance repairs.

One of the things I have noticed about the car is that it takes longer than I would expect to crank. I have to turn the engine over twice as long as my w124 with the same m104 engine.

Tonight, I went to crank it and there was a huge, scary-as-hell, sound as if a bomb went off under the hood. (Not an exaggeration.) I am assuming it was some sort of back-fire.

Immediately after, smoke was pouring out from the front of the car and it smelled like electrical burning.

I waited a few minutes, everything cleared. It then cranked as usual and I drove home.

Any ideas? I appreciate everyone's help. Im literally nervous every time I go to start because im afraid it will happen again.

125k. Drives excellent. Idles with no vibration. Accelerates nicely. No check engine light on.

Okay, did you at least open the hood to see where the explosion like noise came from? Or where the smoke was coming from?

Have you, or the prior owner, had any shady business dealings with people with names like “Guido”, ”Sal” or “Big Tony”?

yes I opened the hood and did not see any clear signs of where the bang came from. it was night time. I drove it today and all is normal. I assume the electrical smell was from wires being exposed to a momentary flame?

Possibly the a/c compressor seized. When this happens, the engaged a/c compressor clutch overheats, and the fusible link in the clutch engagement coil opens up to release the clutch. The smell / smoke will come from the coil and the clutch, if this is the problem.

You can check the compressor clutch by turning the a/c on, and checking whether the 10 mm hex hub bolt is turning with the pulley.

My guess is fuel build up back fired in exhaust system. Need to check Ignition (coil wires, coil , Coil packs etc.)
That would also explain the slow starting...
