Your electrical system is not keeping with demand, check your alternator out put and battery condition and connections if voltage drops all systems stop working (EFI)

It sounds like you have a weak or bad battery. Check with a DVOM and see if you have a reading of between 13.7 and 14.3 with it running. If you do, then your alternator is ok and I would suspect the battery if all connections are good.

89 toyota pickup starts easily but immediately dies


try messing with your idle air if its carbuerated. tighten them down snug (both gas and air or just air depending on vehcile) then turn them 1 1/2 turns each then try starting it. keep doing this until your truck either starts up or you reach the end of the screw. hope this helps oh, and dont crank down on the screws you really dont wanna mess it up.

Car dies when going over really bumpy roads


If the brake pedal goes hard right BEFORE the car dies, and not after, then you could have a problem INSIDE the brake power booster. try to verify this next time it dies at a stop, if you can safely pull the dead car off the road into a driveway (or try to make it stall in a bumpy parking lot) - then before you try to restart the car, open the hood, pull off the rubber hose where it's plugged into the brake power booster --> you SHOULD hear a big "Swoosh" of air being sucked into the booster because there's supposed to be a strong vacuum there even after the car stops running. if you get nothing there, your car is dying of an excessive vacuum leak through the brake booster.= bad booster.

In park the engine dies; only will run if given gas


It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.

Engine will start and rough idle but dies when either the brakes are applied or the lights are turned on!


have you checked out your fuel filter? I had my 2003 denali do the same type of problem and it turned out to be a very dirty fuel filter.
