STARTING PROBLEM WHEN HOT

GMC Other

I have a 1991 oldsmobile delta 88 with 126,000 miles and a 3.8 engine. When car is cold engine starts and runs fine. If you shut it off when it is hot it will not restart, until it cools. I was told it was the ignition module. Changed module and coil pack still have same problem. When engine doent start sprayed starting fluid in throttle body and engine fires. Think it may be the fuel pump but the gm garage says that the pump is eiher good or bad and should not be affected by heat. Please help I cant afford to keep replacing parts. Thanks hyperspeed
