... as described in the Tech Manuals?

'96 Tahoe / 5.7 / 4wd / 2dr

Understand from their diagnostic guide, that applying B+ to this terminal should result in powering the Fuel Pump. Should tell me if the relay is bad. But the Tech Manual doesn't mention where the terminal is located.

Any help?

drivers side back by the hinge for the hood. Should be a single red or brown wire. As soon as you put 12v on it your pump should run.

It should be a red wire. Heres a pic http://www.mhtc.net/~jbomkamp/fuelprime.jpg
The top of the pic is the engine firewall and at the bottom right is the underhood fuse/relay center
