If you have no fuel pressure check the fuse n the underhood fuse block even if its good its still most likely the fuel pump is bad the fuse rarely blows even when the pump is bad,,the 6 cylinder only produces fuel pressure when cranking the enigne

Does a 2001 Saturn S Series have a fuel pump reset button? The fuel pump can be heard, the relay switch clicks and the fuel pump fuse is good.


No reset button check to see if the fuel filter is old. I had one that was clogged up and we had changed the pump for nothing.

Where is the fuel pump relay scudo van please


Most that I know of are on the fire wall. The best thing I tell ppl is the "Haynes manual" for your year and model of your vehicle shows you all that stuff and how to change it.

Where is the fuel relay switch on a 2002 saturn L series


You have a fuse / relay box under your hood. My 2002 L100 special edition, 4 cylinder, is located near the battery. You have a relay and a fuse in series. A fuel pump operations check, section 4-3 of the Haynes Saturn L-series 2000 to 2004 manual, you can hear a soft whirring sound for 1 to 2 seconds when you turn the ignition to the ON position. I can confirm mine makes this sound when I do this. Good luck with the fix.

Note, I had a crack in my fuel pump, but I took it to an ex-Saturn dealer 4 or 5 years ago because I did not want to mess with it at the time. They had the part and fixed it in 4 hours, but it also cost me $1000 to replace the fuel pump and install a new fuel filter.

I replaced fuel pump but did not start,poured fuel in the air breather and it stays on until the fums run out.checked the pressure on the rack and nothing.is there a relay that doesnt work a fuse or is it...


The fuel pump relay is controlled by the PCM which uses the gray and black wires all the way back through the chaissis to the fuel pump. With the key on and no pressure at the rail the pump should be running. If there is no power out of the PCM (Power Train Control Module) to the fuel pump relay the fuel pump will not work

If your looking for the fuse the fuse location is in the FREE owners manual here: (2.62 Mb)
http://www.aboutautomobile.com/OwnerManual/2004/Saturn/ION Check the IGN fuse.... and the fuel pump relay (page 330)

Some fuses are in a fuse block on the driver's side of

the vehicle, near the driver's right leg. Loosen the screw
on the cover and remove the cover.

Have a 1991 Accord that is turning over but will not start. , already change fuel filter still no gas flow. Should I change the relay before I change the the fuel pump? Where is the fuel pump relay switch...


i dont recommend you throw away money like that because 50 is a lot less then 300 plus labor, its still alot. what did you do to check that there was no fuel pressure? did you check your ecu/main relay fuse? and is there no fuel pressure at all? if there is no fuel pressure at all, it would most likely mean a bad main relay. well eithr way, here go the instructions:

Truck will not start, has fire. relay ok. no trouble codes.


when you turn the key in 'on' position, do you hear the fuel pump hum? check under hood in black box,,fuses,,and relays. for bad fuse or fuel pump relay bad. try bumping fuel tank with something hard to see if fuel pump will engauge with key on. maybe bad pump. have you had off road? look for pulled plug from fuel pump underneath near gas tank.have you bent or damaged your igbition key somehow? the key sends a signal to your cars computer to engauge the pump and crankshaft sensor.but if you do have fire,,,it's a fuel problem, so you are on the right track. if nothing i've said helps, check for a bad fuel pressure regulator.hope this helps and thank you for choosing fixya.com!!

Keeps blowing ECM1 fuse


The first thing you should do is to locate the oil pressure switch/sending unit.

This switch serves two functions.

1) provide oil pressure reading

2) disable the fuel pump relay in event of oil pressure loss.

===

When this switch is failing to provide the correct pressure to the ECU. The wiring harness can overheat and eventually create a short.

ECM1 fuse blow is because the harness is grounding/shorting.

===

DO NOT drive the truck until you change the oil pressure switch.

After you change the switch,you should spend sometime to inspect the wiring between the fuel pump relay,ECU and fuel pump.


Please post up day on the comment window/page.

I will follow up on it later.


Good luck.

1993 s10 2.8 tbi the fuel pump fails to pressurize when the key is tunred on, and i have to fuel injector pulse. when a jumper wire is attached i can pressurize the pump but i still have no injector pulse.


There needs to be 60 PSI of fuel pressure in the system to have the fuel injectors to work. There is also a fuel pump relay on the fire wall just left to the brake booster, There is two relays there, i just can not remember which relay is which but try switching the relays with one another. Also check the fuses to the fuel pump and ECM, and the fuel pressure from the shredder valve. Good luck and keep me posted, not a bad Idea to also replace the fuel filter, and that is located at the inside frame rail under the drivers side.
