I am hoping i have a short in my fuel pump relay on my 87 s-10 blazer with a v6.I doubt it but out of the three relays that are on drivers side fender which one is the fuel relay one?My chiltons book dont tell me.

 

I'm new to GM, but I think if you look at the number on all of those relays, they'll be the same. Just swap them out and see what happens. Take some paint or even some of your wife's nail polish and number them so you can put them back where you started with them. Eazy, peezy!!
