    96 SL2. Thought I had all the bugs out but yesterday on 3 occasions with a
    warm engine the engine cranks fine but very hard to start. Looked at a TSB
    referring to this and it mentioned a string of DTC's. Well there are no
    DTC's and when it's cold it fires up perfectly. If you crank long enough
    when this occurs (10-15 seconds) it will fire up and than after a short time
    run well.
    Up to this point I have R&R'd the throttle body and cleaned. New NGK plugs
    (from the Saturn dealer) and new wires carefully routed and cleaned the
    corrosion off the coil towers.
    Ideas?

    Sounds like it could be a coolant temp sensor.

    Kinda my thought too. I figured it might throw a DTC though. Strange little
    car. Every time I think I've got the little bugger figgered out it throws
    something new at me ;-) Really testing my patience.

    You can stick an ohm meter on the coolant temp sensor when its cold and
    then again when its hot. If you had a chart you could compare the
    resistance to the actual temp.
