Did you install the oil pressure switch origional to the tahoe? The tahoe uses a low oil pressure shutdown, instead of an inertia switch to shut off the fuel pump in the event of an accident. If the pressure circuit does not close within 3 seconds after the engine starts the fuel pump shuts off. This is in case the truck is on its side or upside down the pump will shut off.

No power to fuel pump on a 95 Chevy tahoe


Check fuse and power to the fuel pump relay. If your oil pressure sensor reads too low, it might start but won't stay running. Good luck.

Chevy Tahoe sputters than dies


i would first try to replace the fuel filter.usually there filter accumalates debris in the gas tank especially if you you ru the tank close to empty.filter location needs to be traced from the tank toward the motor.you will see a cylinder inline with a strap.part usually runs around 20.00. also when you initally turn the key before start you will hear a hum for about 2 sec. this is the fuel pump pushing the fuel up to motor.so if you hear this pump is working.

1987 chevy s10 2.5l tbi will not start. changed bad fuel pump works well now strong pressure to throttle body. change fuel pressure switch, oil pressure switch, o2 sensor, map sensor, distrib cap, rotor,...


That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.
