Have '99 Blazer that is eating up fuel pump relays--about 5 or 6 in this last half week. Pulled cover off one and appears to burned connection wire inside. When goes out, the relay is very hot to the touch. Resoldered connections at pump as well as elect. taped so know they are secured. Still no improvement. Help needed badly. 2 Answers

Had the problem intermittently this past year but nothing like this. Almost every time the car is cut off (sometimes goes out while driving) if will not start, replacing relay will make it start.
