1999 Buick Regal Q&A
1999 Buick Regal Question: could my fuel pump get to hot in hot weather and make the car stall?
If you have been running your vehicle with low fuel levels frequently, it is possible that when the fuel pump gets hot it will stop working until it cools off. The gasoline actually keeps the fuel pump cool and makes fuel pumps last longer. You may have to replace the fuel pumps to fix problem. This issue may also be caused by a faulty fuel pump relay(found under hood in fuse box). - blueblood1281
