Use Common Sense -> RE: Restarting help (5/11/2008 9:56:45 PM)

That'll get you some quick help...I personally have been out of town, so I could help until now. Maybe nobody has any ideas about your issue. Did the Chevy guys help you? FORD, CHEVY, it doesn't realy matter....An engine is an engine...Now that I have the early morning sarcasm out of the way, lets look at your problem logically.
All engines work the same...Carb'd or injected.
1. Cold starts need a richer Air/Fuel mixture.
2. Warm starts need a leaner Air/Fuel mixture.
Starts fine when cold, so we know that the COLD START portion is working correctly.
Doesn't start when warm or hot, but will when you hold the gas pedal all the way to the floor. Sounds like too much fuel on restart.
On a carb'd engine, holding the pedal all the way down increases the air and decreases the fuel, thus adjusting the air/fuel mixture to a leaner condition.
On a fuel injected engine, holding the gas pedal all the way down to the floor shuts off the injectors, thus doing the same air/fuel mixture adjustment.
Have you pulled the plugs when it doesn't start to see if they are wet? You may have a dirty injector(s) that are dribbling when the engine is shut down causing a flooded condition.
When was the last time any type of injector cleaner run thru them?
