86 firebird 2.8 no start [SOLVED]

[Solved]

All started when I was driving home from work, car died. Did some diagnosis and found out I had no fuel, fuse was fine relay wasn't, replaced relay, still no start, check pump, pump was bad, new pump, still no start.

I got it to work for about 30 seconds when the realy stopped working. The fuse is still fine and I even tried a different one, any help is appreciated.

After some more digging I learned there was no power to any of the connections at the relay

Here is your wiring diagram for your engine. Your fuel pump relay's orange wire should have +12V on it at all times, it gets this power from the fuse called "Inline fuse 3 20A" which is under the hood. Your next check should be that fuse, it's a black plastic kinda nondescript looking thing hanging around the right (passenger's side) fender.
