I have a 1988 560SL. It will start fine cold, starts right up, hardly any cranking. But, if I drive it 5 miles & shut down, then try to re-start, it won't start. I've changed plugs, plug wires, dist. cap, rotor, fuel filter, and fuel accumulator.
It has a hot spark, but I can't smell any fuel when I try to start it. Sometimes pumping the accelator will get it started but not always & it's getting worse. The only other symptom is when hot & I first crank it, it will sometimes try to run on just a feww cyclinders, then stalls. HELP!
