Question about 2000 Chevrolet S-10
We have changed the fuel pump, the fuses, and the relays. We cleaned the grounds because we noticed a power increase when we moved them. Could it be the computer? It is next to the grounds we were shaking. We could not get the power increase to repeat after we cleaned the grounds. I'm thinking the only thing left is the computer, but I don't want to spend that money without more support from anyone that is familiar with this problem. I'm looking for any ideas to get this thing running again.

The fuel pump relay is located Under hood, driver side, upper firewall, mounted in
The fuse is located under the instrument panel to the left of the steering column. The fuse block should be visible from underneath the steering column, near the pedal bracket. If the panel is not visible, check for a removable compartment door or trim panel which may be used on later models to hide the block.

undo the fuel line where it joins the fuel rail to your injectors.. it is under extreme pressure so be careful.. get someone to crank car for a second or two and if fuel sprays out then its not a fuel problem..

You may have power there, the PCM will cut power to the pump relay after a few seconds if the motor isn't running. Check it when the keys first turned on - you may have to have to have a helper. If you don't have any power then, check the ecm1 &2 fuses.

SOURCE: I am not getting a
The fuel pump relay is powered by a fusible link connected to the starter solenoid on the positive battery terminal. That fusible link feeds the 10 amp fuse near the relay. You can test the fusible links with a 12 volt test lamp. If the fusible link test okay check for an open circuit in the wire between the link and the 10 amp fuse. Hope this gets you fixed.

the oil pressure switch's 3rd wire is to the fuel pump's priming circuit. That circuit is used upon starting the engine providing fuel pressure to the injectors
Once oil pressure is acheived the relay takes over by the PCM's command signal. Your explaination on your problem is not detailed enough to determine the problem. How long does the engine rune before dieing out?
