    Dident you chk. the fuse and relay, and did you run 12V directly to the pump to see if it would run before you went to all the trouble of droping the tank?

How do i replace the fuel pump on a 1992 gmc sonoma?


The fuel pump is in the tank, tank can be droped out to chg.pump, Its up to you how you want to do it but for me i always found it easier to unbolt the bed and lift it back about a foot and i could get right at it, and i did not have to mess with the tank straps and fuel lines, If that is the problem. Chk.fuses and relay first.
