Can't find the fuel pump

There is no fuel shut off switch on Oldsmobile or any other GM vehicle . When fueling the vehicle did you stop when the pump kicked off ? or did you continue to fill to top ? Flooded the charcoal canister an engine ! Is the check engine light coming on !

could have plugged fuel filter check see if you have fuel pressure.if no check fuel pump fuse or relay.

If you have voltage at the fuse and relay, and at the pump, but no fuel pressure, I would say the pump has died or the tank is empty.
Have you checked for voltage at the pump yet ?

• Hi, I can help.

• The fuel pump relay is 4th over on the very bottom row of the relay panel under the hood. This can be the pump too. The pump holds pressure and when the back pressure switch fails the car won't start. Or the pump could just be out period. The fuel filter can do this too.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.

Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump. ----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

Try looking at the fuel filter, it might be partly clogged or just clogged.Locate the fuel filter, disconnect it and (I know this sounds strange) blow through it, if you get resistance of any kind, then it's bad, if it blows completely through with NO resistance at all, then it's good.

take the intake tube off the throttle body and spray your starting fluid in there. if it starts then dies, its your fuel pump. it could also be the pump relay, or inertia switch, aka emergency shut-off switch

Make shure both battery cables are tight especialy the pos side since there are 2 cables with a washer between the cables. they come loose all the time.
