Its in the glove box behind a panal .But the way this system works is its a split curcit and the oil pressure sendind unit is feed from the same fuse and also goes to the fuel pump with B+. Its a safty thing. So if the relay fails while driveing the fuel pump will still get power through the oil pressure sending unit.. The best way to tell if the relay is bad is how long it takes to start cold .If it fires up quick then the relay is good and the problem is likely with the oil pressure sending unit or something else fuel related like the fuel filter or fuel pump . I fit takes a long crank time when cold then it may be the relay because it will take some time to build up enought oil pressure to trip the oil pressure switch and send voltage to the fuel pump. Also all of the relays in the glove box are interchangable all the same so you can test this way to take the fog light one

SOURCE: cant locate or reset fuel pump relay on 89

Ok. First you can't "turn on" a relay. It is either working or it isn't. "several electrical accessories in the vehicle use relays to transmit the electrical signal to the component. If the relay is defective. that component will not function properly." ( Haynes Repair Manual, General Motors 1988-2002, p12-5) Your fuel pump relay should be located under the hood in the fuse box on the right (passenger side) of the car. It is a black square approximately 1" by 1". Replace it if your fuel pump isn't working as a cheap method of elimination.

SOURCE: 1999 oldsmobile silhouette van won't start. no power to fuel pump

I have a silhouette and it had the same problem
Follow the fuel pump wiring harness to where it plugs into the floor of the van--pull the connectors apart--they will probably be corroded, and you will possibly have to change both wiring harnesses or connectors.

SOURCE: 2003 Oldsmobile Alero will not start. Already

I have a 2003 alero that would not start. It was actually a security problem it locks itself up, there is a quick fix for it though you turn the car to the on position wait 10 min. turn it off for 5 sec. and then turn it over and it should start. Sounds to easy right, thats what I thought someone found it out for me online before I had to throw a bunch of money into it, like others have. HOPEFULLY this will work for you too.

Were is a fuel pump relay switch located on a 2000 Oldsmobile intrigued


Hey James , It's in the under hood fuse box , F/PMP relay an there is a fuse F/PMP 15 amp. Underhood Accessory Wiring Junction Block
Right side of the engine compartment, mounted to the strut tower

The PCM controls the fuel pump relay by supplying switched ignition voltage to the fuel pump relay coil. When the ignition switch is first turned On, the PCM energizes the fuel pump relay. The relay contacts close applying power to the fuel pump. The fuel pump relay will remain On as long as the engine is running or cranking and the PCM is receiving reference pulses. If no reference pulses are present, the PCM de-energizes the fuel pump relay within 2 seconds. With the engine stopped, the fuel pump can be turned On with a scan tool.
If the PCM detects a problem on the relay control circuit, DTC P0230 will set. Use this table if DTC P0230 is not set and a problem exists with the fuel pump!

What if any and where is the 1997 Oldsmobile fuel pump switch location. Installed new pump and would not start. I am being asked if we turned on the switch? What switch?


The fuel pump is controlled by a fuel pump relay, and the relay is powered by a fusible link attached at the starter positive cable, and there is also an inline fuse between the fusible link and the relay. Check at the fuel pump connector at the fuel tank for current. When the ignition switch is turned on, engine not running, the fuel pump should receive current for about 3 to 5 seconds; then the ignition has to be turned off for about 10 seconds, and when turned to the on position should give power to the fuel pump again for a 3 to 5 second interval. If ther4's no power at the fuel pump connector the problem is either the relay or the wiring between the fusible link and the relay.

Hello tcb476: My name is Roger and i will answer your question. The fuel pump relay on your Oldsmobile Achieva is located under the hood. Open the hood and look at the left strut tower. You should find a relay block attached to the tower..There should be 4 relays. Three of them will be in a row. The center relay should be your fuel pump relay. Please rate the answer you received as this is how we know you received the correct information. Should you need further help please just ask. Thank You for using Fix Ya. Roger
