Fuel pump not running

You will find a reset button on the Inertia switch. The Inertia switch may be in the trunk or behind the kick panels of the front seat floorboards.

The Inertia switch is a safety device which cuts off the power to the fuel pump after a bump or collision. If closing a door or trunklid hits the right frequency, the switch will cut the power. Just reset it.

Some vehicles have a fuel pump cut off switch that shuts all power to fuel pump in case of an accident. It activates by inertia...meaning that a severe "bump" will activate switch, thereby cutting off the fuel pump. If your vehicle has that switch, hitting that bump may have activated switch. If you do have that switch, reset it by pressing in the reset button.

No power to pump, installed new pump

Check the fuse first.

Did your car get hit? I believe the taurus' have a fuel pump cut-off that is tripped when the car is bumped. There is a button in the trunk to reset it IIRC.

While driving hit a bump vehicle stalled now only cranks has a high smell of fuel but no spark

You need to reset the fuel pump cut off switch. It turns the pump off when in accident, so gas doesn't keep pumping. It is usually up under the passenger side floorboard near the top of the carpet.

A sudden stop of my car santamo model 1996 due to no fuel to the gasoline engine

look for the fuel cut out switch, normally on these under the hood, or fuel pump , or relay failure, if you stopped suddenly or hit a bump then the cut out, if thats not it find the relays and pull out and put back in in case of a bad connection, then work back, if you switch on the ign you should hear the pump make a noise if its working

Few months ago had fuel pump assembly replaced. Not the pump but the assembly. Location is behind the rear seat above the fuel tank and actually its in the tank but can be reached by removing the rear seat...

I would say that you are on the right track , I think that maybe when the work was done on the fuel pump assy the mechanic may have pinched the power wire and hitting the bumps has caused it to will have to take the seats out again (sorry).You need to look for a damaged wire or evidence of arcing .Hope this helps.

I hit a small bump. My car cut off and would not start back. It will turn over but will not crank.

hi its probably the fuel cut off switch. in an impact an enerchia switch will cut off the fuel pump. your local dealer will tell you where its fitted and its just a push of the switch and away it will go.
