I have a 92 cavalier. I hit a hard bump and the car shut down. Fuel pump will run, but not when you turn the key, only when you supply power to the test wire.

There should be a relay for the fuel pump under the hood, you may have burned that out when you hit the bump. If it is burned out then you have to look at why it did it. Hitting a bump shouldn't have caused it to happen unless you might have broken a ground when hitting the bump.

I recently got in accident 2010 Ford escape air bag went off now car won't kick over need. To know if there a switch that shuts off car like a kil switch please help me out thanks brandi

HI Brandi. Sorry to hear about your accident, hope your ok. Ford has a very good safety switch that shuts off the fuel system in case of an accident. The worst thing is that it will go off if you hit a bump real hard out you hit a speed bump. Now here it's the tricky part. Do you have the owners manual? If you do look for the section on emergency shut off switch. In some cases out cars it's hidden on the passengers. If your sitting in the passenger seat, where your right foot would be there is a little push switch under the carpet against the panel. Where the carpet goes up the side, you should be able to lift it away. You may feel a little protrusion. The switch needs to be pushed down. IF ITS NOT ON THAT SIDE, LOOK IN SAME AREA ON DRIVES SIDE. IF YOU DON'T HAVE THE MANUAL, YOU CAN GO ON ANY OF THE U-TUBE SITES. IN SEARCH, LOOK FOR RESETTING FUEL SHUT OFF SWITCH. LET ME KNOW IF IT HELPS. Are you driving with the air bag sucking out of the steering wheel?

2003 Toyota Avalon xls model all lights and dials on instrument panel go off and engine stops when I go over bumps. I wait 2 minutes and car starts up again and runs fine until I go over bumps again.

The very first thing I would check would be if the battery cables are clean and tight. After that I'd lean towards a bad ignition switch. Do you have a ton of keys on your keyring? wiggle your key while its on to see if you can recreate the problem.

Gauges in my 1998 plymouth neon stopped working when i hit a bump

Sounds like an intermittent loss of power to the instrument cluster to me. Remove the instrument cluster and inspect the electrical connectors on the back of the cluster.

Hi. I have an '02 Hyundai Accent. It has shut off 3 times while I'm driving, with no electrical response. I wait it out and it eventually starts up. For the past few months the instrument panel lights go...

Different areas worth checking in order of seriousness are:

  • loose battery cables/terminals - if they are loose, a bump could temporarily disrupt your connection
  • loose battery - the battery itself may be moving around in it's compartment when you hit a bump or jump on the brakes
  • defective alternator - the alternator gives off several symptoms when it's on it's way out. interference when the radio is on, very slow windshield wipers, dim headlights.
Bring the car to any of the bigger chain autoparts stores that feature a free electrical test. They could rule out a bad alternator or possibly narrow down what you should do next.

Where is the fuel injecton shut off system in a 2002 ford explorer, I found the reset swith but can't locate the shut off system

The reset switch is where the 'inertia' shutoff switch is which will trip when getting hit hard from behind or hitting a bump in the road.

Hitting the button resets the inertia switch.

When i hit a bump the car sputters but stays on and the radio will turn off and the digital instrument panel resets

Check your battery & cable connections- including ground connections. You likely have a loose connection or short that joggles when you hit a bump. Fix it before it fixes you.
Good luck! If this fixes ya please rate this solution
