1993 Buick Regal Limited 3.8L

I've got a Buick Regal Limited, 3.8L, with approx. 210,000 miles....starts when it is cold and runs fine, but will not when it is warm....have had it towed twice, so am reluctant to hit the road until the problem is taken care of. Car does turn over when it is warm, but will not start. If I let it sit for a couple of hours, it typically will start, but not always. Does not appear to be a gas issue, but electrical or sensor maybe? Any suggestions?

Does it stall when it gets warm or just won't restart after you turn it off?

it just won't start.....once it starts there is no problem with idling, excelleration or response....

I'm thinking that you might not be getting the 3x crank signal when the crank sensor gets hot. We need more info to be sure. Next time it won't start check for :
Fuel at the injector rail.
Spark at each of the three front cylinders.
Fuel injector pulse.

i had the same problem in my 92 olds 98. i changed the fuel pump and ecm and had no problems since. not sure which one was the cause but its fixed now.
