The MAP sensor - another frequent cause of stalling or non-starting. This measures the air pressure in the manifold. You can test it - if your car won't start, just unplug the electrical connection from the MAP sensor. If it starts, replace the sensor. MAP sensor details. (It may act as though the fuel pump is not working properly - starting, then quickly dying).

What can cause Malibu 98 to sputter and stop while parked?
Check the vacuum line on the map sensor for dry rot or other damage. If vacuum line on map sensor is in good condition the map sensor itself may be faulty and need replaced. The car will run with either a faulty map sensor or vacuum line. It would just run badly or stall. It might throw a code but not all the time. Also could be an ignition system problem or spark plugs needing replaced or the oxygen sensor may be faulty.

92 Chevy 350 tbi gitting to much fuel?
If that's going on there is some kind of malfunction somewhere. Check for a dirty air filter, sticking TBI injector, faulty throttle position sensor or possibly some other sensor failure.
