2000 Mitsubishi gallant turns over but won't start. The key I have won't open the trunk so I can push the fuel pump reset button. Why?

When you turn the ignition key, can you hear the fuel pump humming? If not, check the fuses, next the reset button in the trunk.

The adding of the oil is more than likely just a coincidence . If you don't have power at your fuel pump check to make sure your fuel pump fuse is good. Also in the trunk you should have an emergency fuel pump cut off button. ( normally on left side rearmost area behind the plastic panel ) there should be a hole in the plastic to poke your finger in to push the reset button. If those are ok then check to make sure your fuel pump relay is working. Find that, turn key all the way to on but not starting. Listen for fuel pump to turn on for a few seconds ( priming the system ) if it don't use the handle of a screw driver and tap on the relay and if it clicks and fuel pump runs then your relay is failing. Replace that with a new one.

Have you checked the fuel shutoff switch? it's a safety device to shut off fuel flow in case of severe front or rear impacts, but sometimes it just trips for unknown reasons. It's behind the liner on the driver's side of the trunk. Look at the round opening on top: if you can see that the red button is setting level with top of the switch it has been activated. To reset it, push the button back down until it "clicks" into place (usually 1/2 inch down or so). If it has been activated and the button will not reset the unit must be replaced, and it is a dealer only item.

- to check fuel pump/relay- with drivers door open - radio off - insert key and turn from OFF to RUN-not start- should hear a hum from under car back towards tank- relay is under hood in second fuse/relay panel
? did you hit a bump just before car shut off? - if so look in manual for location of EMERGENY FUEL CUTOFF- usually in trunk area- large red push button- can trip sometimes with a hard enough jolt

ricks63toy, I believe that Ford still uses what is called an inertia switch even in the hybrids. This switch will shut off in the event of an accident shutting off the fuel pump. This is a safety feature built into the vehicle. Seeing that this is a newer vehicle I trust that you still have the manual. If not, the switches are usually located in the trunk. Look on the side walls of the trunk and see if you can locate it. It is usually marked by a sticker. When you find the switch, push the red button down until you hear a click. This will reset the switch and allow power back to your fuel pump. Good luck with this.

You need to reset the alarm system.That can be done with the remote entry key fob or by locking then unlocking the drivers door with the ignition key with all doors closed.This is for a factory alarm system.Also check the inertia switch,should be in the trunk,on the side with a push button top.Push button.If already down its not tripped.

in the trunk same side as fuel filler, red button push in then turn key on to run position then off do that 5 times then try starting. the last procedures is to prime the pump.

Either no fuel or no spark.

just press the button to reset it. Per your owner manual. Should only trip in an accident.

WHen you turn on the key, can you hear the fuel pump run for 5 seconds. The pump is in the fuel tank. listen there while someone turns the key on. report back.

it is normally located in the trunk on the right side a button if you can not find it there in the trunk give these guys a call its Schrams auto & truck parts 1-800-292-1032 the website is www.schramauto.com and maybe they can help you they sell only GM-parts
