Why wont my car stay running after it stars?

Check the gears on the distributor.

You might want to remove the o2 sensor ahead of the catalytic converter and see if it will run. If it does you have a plugged catalytic converter or muffler. You can also try manually spraying gas into the throttle body and see if it stays running and if so you could have a bad fuel pressure regulator. You will also need to check the pickup wire in the dist to make sure you are getting fire or enough fire to the plugs. You can check for this by putting a tester in the spark plug wire and the other end on a spark plugs if you have a spark tester. Hope this helps.

First you must determine if the fuel is stopping or the spark is stopping..If the fuel is stopping this could be a computer problem.. If the spark is stopping then it could be the IGN Module in the distributer. or any nomber of sensors. Squirt a little fuel directly into the Throttle body on the intake manifold.. If the truck runs longer its probably loss of fuel.. Do this several times to make sure, be careful and only use a small amounty of fuel.. you do not want a fire.. RE: Spark: Take a plug wire and an old plug..put the wire on the plug.. hold the plug against a good ground .. have someone crank the engine .. does the plug stop firing? The engine dies.. and will not restart for a minuet or so.. during this "no start" time do the plug test. If the plug will not fire during this time take the module out and take it to Orillys Auto parts.. They can test it.. really expensive part. Don't replace until you know it is BAD..

Check that the fuel pump is working and pumping fuel (fuse or burnt out) as it sounds like there is no fuel in the carby. To check if the engine is going to run remove the air filter from the top of the carby and pour about a table spoon of fuel directly into the carby throat. Replace the air filter and crank the engine. If is going to run it will fire and then stop

okay if you have spark sounds like fuel delivery... if pump is new then check the fuel filter..... if filter is good check to see if there is a secondary fuel pump bolted to the driver side frame rail.... if everything checks out fine find the inertia switch and reset it it is possible it can trip.... it is a fuel shut off switch designed to trip and shut off fuel in case of an accident but malfunctions do sometimes occure with them... hope this helps

If you have spark but will not styart without atarting fluid the you need to replace fuel pump and fuel filter if you have spark and no fuel your car will nit start and vice versa.

You say it isn't getting spark either. Have you checked the ignition module?

hi i have a 1997 chevy tahoe that starts but won't stay running i have changed fuel pump, fuel filter,relay ,spark plugs, and just changed rotor and dis. cap ready need some help to figure this out please.

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

have you checked the fuel pump or the coil pack to see if its getting gas or spark?
and depending on the crack i would replace that rotor button as well
