Hello everyone, need help badly, I've got a 99 blazer Lt 4wd project truck,it ran when parked but lost key. Got a new switch put in it and had to re learn the passlock. Got that took care of and now no fuel, the fuel pump isn't running, I've checked everything. I have one relay under the dash that gets hot and I can't find a proper diagram for those relays, I don't know what to do. I can pour gas in the carb and it'll run till the gas is gone but I feel like there is something electrical I'm missing cause the owner before me had a really expensive sound system in it and lights and stuff, I've got amp wires and speaker wires everywhere, I've checked and don't see anything bare that could Arc or nothing that looks rigged, it's all pretty professional looking, I've got 5 tweeters between the

I think this is supposed to be bolted up and I don't know what these relays are exactly


front and back lol and good door speakers but the amps and subs are gone,anyway sorry for the book. Just looking for any advice I can get, thank you all for having me

 

What you are holding is the Body Relay Block. It is a bear to get out! But it is not so hard to get back in as it slides into a slot. There are several threads and posts on accessing the BRB (even one by me). Use BRB or Body Relay Block in your search window and you'll find them. If you can't, let us know.

I'm attaching some scans of my 99 GM Service Manual I have for my 99 LT relating to the BRB. Let us know if they help.

 

This could help.

 

Isn't the fuel pump relay under the hood,with a marked diagram under the cover?
