Hi, what I looked at was s10 vinW. Check the ecm/ bat fuse-- 20 amp. Use a testlite on the circuit. There is also an oil pressure switch in the fuel pump circuit, parallel to the relay. Once you crank it enough to bring up oil pressure and that switch closes, the pump should run, even without the relay. Diagram below.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
