Car dies on right turns, will restart, will not stay running

one of two things come to my mind in hearing this , 1st damaged inertia pump switch (this switch shuts off fuel pump in case of high Inertia-wreck) 2nd the fuel pick up or baffles inside fuel tank have broken off this will require the removal of the tank for a look at it

Truck starts runs momentarily quits only starts after turning switch off then restarting

More in likely the Fuel pump, when you turn the key on the noise you hear is fuel being pumped to start the vehicle.... if it's shutting off after it starts it's Not getting fuel ?

Car shutting off

whilst i am not familiar with the actual car i would say...
if it cuts out immediately then its electrical...check coil, ignition amplifier etc.
If the car cuts slowly by losing power, spluttering etc it will be fuel related....fuel pump, fuel pump relay, fuel filter.
Does the car restart immediately or do you have to leave it for a while?
what happens just prior to the vehicle shutting down?

Car will turn over but won't start. Through the

No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

Where is the fuel pump? is it in gas tank? the car will start go a few blocks and shut off and not restart. I think it is fuel pump, may be fuel filter I also need to replace throttle positioning switch....

yes it is in the tank. but you can remove the rear seat to get to the fuel pump, instead of dropping tank. (2003 to 2005) kia sorento. fuel filter is inside tank and replaced with fuel pump as an assembly.

Fuel Cut off switch location

your owner manual will tell you.

here is for 96 tracer. don't have 89 but suspect same place in trunk.

In the event of a collision, the electrical contacts in the IFS switch open and the fuel pump (9350) automatically shuts off. The fuel pump will shut off even if the engine (6007) does not stop running. The engine, however, will stop a few seconds after the fuel pump stops. It is not possible to restart the engine until the IFS switch is manually reset. The IFS switch is located on the RH side of the luggage compartment. Access is gained through a hole in the luggage compartment back lower trim cover (40374).


To reset the IFS switch, depress the button on top of the IFS switch.
