The fuse is under the hood on the drivers side inner fender their is a fuse box their.If you have power their then check power at the fuel pump relay which is located in the glove box on the passenger side inside the vehicle,there is a cover in the back of glove box remove the panel and their is 3 relays their you should feel the relay clicking for about 3 seconds when you turn the key on. Check for power their if there is power their then you must check for power at the fuel pump. ZThere is a connector right on top of the fuel pump on top of the tank,you should be able to get to it from under the truck without removing the tank.The common cause on these trucks is the connector on top of the fuel pump melts and causes an intermitent problem. if you have power their for about 3-5 seconds this is OK. You must then replace the fuel pump.It is fairly easy on these trucks. Drain the fuel if you can then undue the 2 hose clamps on the filler and vent tubes,then you put a jack under the fuel tank with a piece of wood on it and remove the 2 fuel tank strap nut and bolt, lower the fuel tank and then remove the fuel line carefully do not break them they are hard plastic lines they can brake easily and be costly then remove from under the truck.Take the time to clean around the fuel sending unit and pump to prevent dirt from getting in the tank and causing lots of problems.Remove the retaining ring with a screwdriver and Hammer,and the pump assembly will pull out. Replace the pump assembly and reverse the procedure for install.They usually supply you with a new wire connector when you buy the new pump USE IT. Remeber to replace fuel filter at the same time. Hope this helps

How do you reset a fuel pump in a 1998 chevy s10 truck 2.2 liter engine, 2 wheel drive? The truck hit a curb going pretty fast and now when you turn the key on the fuel pump does not come on. Is there an...

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.

97 chevy 4.3 liter no spark no fuel pump running.

4.3 and 2.8 motors have a ceramic module in the distributor. if you have alot of miles on the truck, and there is no spark, that module is usually the culprit. easy to replace with a nut driver and some dielectric grease. mod is located in the distributor when you take the cap off look straight dowm and its right there.
also check eec relay and fuse. that will also cause the prob.

The crank sensor is only an impuls unit that gives current to the coil pack.has nothing to do with the fuel system.Try changing the relay if you are getting no power to the pump and only one live connection.

Fuel problems cant get car to start

FUSE SHOULD BE UNDER THE DASHBOARD ON THE DRIVERS' SIDE. WHEN YOU CHANGED THE PUMP, YOU NEED TO CHANGE THE FUEL FILTER AS WELL TO MAINTAIN THE WARANTY. I WOULD CHANGE THE FUSE AND FILTER. HOPE THIS HELPS. LET ME KNOW HOW YOUR DOING. BEST OF LUCK
