Here's the background. The car always starts well from cold, 1st or 2nd turn and it fires right up. When off for 5 minutes after running for a while to full heat-up, it fires right up. But if I leave it off for much more than 5 minutes, it cranks and cranks, but does not fire for three to five extended cranking sessions, and then it fires up. But it spudders, like running on 1-5 cylinders, then gradually smooths to a normal idle.

This has been the case regarless of ambient temperature or moisture. Once fired-up, it always runs smoothly. New parts now include: fuel pump, fuel filter, accumulator, injectors, cap, and rotor. Ignition wires are fine.

In the MB manual for the M110 engine, there is a reference to a "Hot-start Device" (M110's '77-81) which includes a Hot-start Relay and a Hot-start Solenoid. I've tried to track down a Hot-start solenoid through FastLand and my local MB dealer, but no one has ever heard of these parts.

Anyone have any experience with the K-jetronic and a Hot-start problem?

Thanks, Alex
