you must have a short to another power circuit unplug the pump and chk the pwr wire to see if it still has pwr if it does trace the wire to find the short I FOUND ON MY 98 Chevy S-10 THAT THE OIL PRESSURE RELAY ACTS AS A DUAL BACKUP FROM BATTERY THAT WILL ALSO TURN FUEL PUMP ON ALL THE TIME IF IT IS BAD EVEN WITH THE KEY OFF
yes especially if installed in an automobile it may pump but not build pressure.
if this is an electric pump did you check fuse and relays
I have the exact same problem. After replacing the fuel pump everything was fine. Now the fuel pump does not always kick on and you have to turn the ignition on and off until you hear the fuel pump kick in. Went to start this morning and fuel pump did not kick in, still wont. So I checked the relays, all good. Now the fuel pump kicks on but it still wont start. Did the computer on this thing die?
The fuel pump is in the fuel tank. The tank has to be removed to access. The pump is computer controlled with relays.
No, it only has one fuel pump relay.
Check your relays first. The fuel pump is inside the fuel tank.
installed wrong or bad fuel pump
No reset switch on a Jeep. The fuel pump is computer controlled with relays.
Not often, it is usually the fuel pump that fails.
Fuel pump fuse blown or the fuel pump is defective even if you hear it running. Fuel filter can also be clogged.
Blown fuse or bad fuel pump relay.
did u also check the autoshutdown and fuel pump relays?
The fuel pump relay is to move the fuel from the primary tank to the engine itself. To accurately answer your question I would have to know the exact fuel pump you want to know about
The EEC Power and fuel pump relays are behind the computer on the passenger side under the dash. The relay on the blower bracket is the fuel pump.
The fuel pump relay feeds power to the fuel pump. The relay is commonly mounted under the hood with the other vehicle relays.
Mounted on top and inside the fuel tank.
its probably hunted its probably hunted
AC and fuel pump are the same relay
most likely fuel pump is not running, this could mean bad fuel pump, but first i would check all fuses and relays related to the fuel pump
the fuel pump relay is located behind the battery.There should be 2 relays, they look alike, but if you look closely it has fuel pump relay on the top.
on the firwall on the driver side there are 3 relays, one is the fuel pump relay
Where is the fuel pump relay switch located on a 1994 Grand Am SE
Check the fuses and relays.
The fuel pump will still try to pump fuel even if the tank is empty.
