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.

Asked by PawPaw1946 Oct 13, 2013 at 09:39 AM about the 1999 Chevrolet Blazer LT 4-Door RWD

Question type: Maintenance & Repair

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.

Thanks for the info. Hope others might be as helpful. Anything else that might allow the amps to be higher than allowed before I spend on new pump?

Installed new pump and filter, assembled fuse block under hood, then as I was reconnecting Ground I had a spark. Heard I think, a pop on fuse block side and now have no power at all. Sure battery is good. Frustrated- - you bet. Am I looking at another relay or a fusable link? HELP!
