Warm Starts having problems starting

The problem is that our 1988 560SL has problems starting after the engine is warm. There is never a problem when the engine is started cold. We have replaced the eight fuel injectors, but left the cold start fuel injector alone. We also replaced the spark plugs. The problem still exists when the engine is warm and you need to start the car up. The starter turns over but it is very hard to start.

Does anyone have any ideas of what I should do? What else could it be? Short of getting a full tuneup by replaceing the wires and rotor I'm not sure what else could be cauing this problem.

When this happend to me, it was a combination of new fuel filter, gas cap and accumulator. I was either losing pressure or there was blockage. Yours sounds more like a pressure problem...cap and accumulator. Start with the gas cap
