TBI problem: no fuel pump signal (1 Viewer)

[FLYINGLOW]

Like the title says. It will start if it has been sitting for a couple hours, but cuts out after a minute. I am getting no signal to the pump relay after it cuts out. I am going to get the code out of the computer, but don't know when I'll have time to do it and was wondering if anyone has had the same problem.

edit: its a GM 4.3 system installed on a 2F

Is it running and then cut out? When the pump went on my vortec 4.3 the fuse had gone also.

It'll start when I first try it and run for a bit (30 sec or a minute) and then die. I am getting no signal (energizing voltage) to the pump relay. Too Tall is coming over to wheel and I got no time to work on it!
