The oil pressure sending unit could be bad. If your oil pressure gets below 7psi than it shuts off all power going to the fuel pump. It is screwed into the engine block just to the right of the distributor.
For the 1998 s10 theres no fuelpump switch, there is a fuelpump relay. the relay is in the engine compartment inside the fuse/relay box. the relay will be labeled on the inside cover of the fuse/relay box cover. besides the relay the only other problem for a fuelpump not working on these trucks is the fuelpump is bad or the wiring connector to the pump is bad.
No, no reset for an S10. There would be a fuel pump relay under the hood in the fuse/relay block. And also a 10 or 15 amp fuse for the pump at this junction block as well.
Check the fuse, then find the tank electrical connector, pull it apart and find the gray wire -the fuel pump wire. Clip a test light lead to ground then put the tester probe into the gray wire terminal on the harness side of connector. Now have a helper turn the key to start and crank the engine over. The test light should light up if your electrical circuit is working. Before you drop the tank to investigate the fuel pump (it probably needs replacing), check if the ground for the pump is alright. Maybe when you hit the curb, you jarred loose the ground connection.
So is the pump running or not? fuse good? relay good? Fuel pressure is???you may need to have a repair shop check it, you dont want to waste anymore time and money guessing.
Hi:
You must first drain and lower the fuel tank, as your pump is mounted inside. With the fuel tank supported, undo the tank mounting straps, and the filler hose, then slowly lower it until you can disconnect the fuel lines and electrical harness. The pump assembly is now accessable. Remove and replace the assembly , then reinstall the tank .
Check the cable that goes from your battery to the fuse box the relay that is clicking is on. Check for lose bolts or corrosion of the contacts or something like that. If the relay is clicking it sounds to me like it is a voltage issue going to the relay.
