Where is the fuel shut off switch in my 2002 mazda 626


Your vehicle does not have an impact activated fuel shut off switch like the ford vehicles. Power is provided to the fuel pump by the fuel pump relay. Power is provided to the fuel pump relay by the Main relay. Both relays are controlled by the Engine computer or PCM. The PCM can disable the fuel system by not energizing the fuel pump relay if the immobilizer system has been triggered by the use of a non-authorized ignition key being used to start the vehicle. This should also trigger the security light to be flashing on the instrument cluster as well. Look for that rapidly flashing security light to see if this is the problem.

Truck shuts off


Sounds like a fuel sensor either fuel pressure tank pressure or a bad fuel pump either way it seems your fuel pump is shutting down. It could also be related to the security system scan the vehicle for sensor codes or security faults also if the ignition key is worn it could cause the computer to read it as a bump key and activate the anti theft system

Chevy tahoe crank but not start i hear the fuel pump


These vehicles are prone to failed antitheft security systems. When these fail, the system shuts down the fuel injectors because the security can't read the key properly.

I put fuel pump ,crank sensor, fuel filter, tune up and I still do the same start and shut off


Does it have a SECURITY system in it ?
Is the SECURITY Light on or Flashing Sparatickly ?
Any Trouble codes ?
POSSIBLE - * MAF sensor (Mass Air Flow Sensor) has gone BAD causing car to start then shut back off . * Security has kicked in ( Due to changing stereo system or battery went dead or didn't have one on it for a little while .
FIXES - *Replace Mass Air Flow Sensor (in between the throttle and the air filter box) . * Take to Dealer and have computer Flashed/Reset if SECURITY is at Fault . I recommend the MAF sensor

My 2003 Pontiac Grandam will shut down while I'm driving and it has to do with the security system


The security system is called Passlock. And yes it will turn off the fuel injectors when it starts to fail. Go check out this link, should help inform you about how the system works along with some ways to get around it.

Engine starts, but shuts off like the fuel pump is out, good fuel pressure. security light on dash on. ideas?


yes some times a security system will allow car to start and get as far as 5-10 feet and shut down as if out of fuel but the security system acts like it is being stolen. if it is a factory install then call dealer and see if you can overide it with a sequence of procedures.

My 1994 grand cherokee 4x4 6 cyl. Will start for like 5 sec and then shut right off. i have no idea what the problem is. i think it might be the security system. How do i rip out the security system?


are you sure you have fuel pressure ? alarm systems usually kill the starter circuit not the ignition you need to put a fuel pressure gauge on the fuel rail you should have about 40-45 pounds of fuel pressure . hope this helps

I bypassed the security system the car still want start I placed a hot wire directly on starter and the car turned over but there was no fuel going up what is the problem now


Try hooking the security system up again so that it's functional, then take out the fuse that's located on the fuse box in the trunk that's associated with the security system. It should be labeled "theft" and it's a 10amp fuse. The system will still function as normal only the horn will not sound if the security system is tripped and it will not shut down the fuel pump.
