You need to have the throttle body cleaned and adjusted, and if it still acts up, then the idle motor may need cleaning or replacement. There are other possibilities, but start here.

93 toyota pickup 4x4 it will stay running after I turn it on to start it up, it starts up then after a few seconds it kills


if I'm reading this right...
... the engine starts and dies within a few seconds.
... you jumpered the fuel pump test connector and it will keep running.
... you smell fuel after trying to re-start when it dies.

Disconnect the plug to the cold start injector. Even if you have an issue with the engine running then dying after a few seconds after doing this, if you don't smell fuel after disconnecting the cold start injector and try to restart it, the cold start time injector time switch may be failing.

Buy a can of starting fluid and have someone start the engine then spray short bursts of the fluid around all the intake fittings. If spraying the fluid in any particular area keeps the engine running, I'd start looking for leaks around that area.


It does sound like an AFM or COR issue considering it dies after a few seconds, but the fuel smell when trying to restart the engine may be a separate issue that needs corrected / isolated first.it will keep running.

My 1990 chevy lumina will start up for few seconds then die. it wont stay running for more than 5 seconds but will starts up every time. when i give it gas it dies immediately


Sounds like low fuel pressure. Check your fuel pressure. If you have the 3.1 liter engine and just turn the key to the "on" position you should have around 41 - 47 PSI. When running it should have about 31 - 44 PSI. If you have the 2.5 liter engine you should have 26 - 32 PSI of pressure when running. I hope this helps and good luck.

It acts like it wants to start but won't actually stay running...... Dies after a few seconds.


hi.

this is because the engine starts running when you press start button using the starting motor.

so it reaches its required speed fuel is been injected. you say it jus starts and dies in few seconds

following may be the reason
1.fuel is not coming to the fuel injector so no firing.
2.timing belt is not set properlly
3.speed sensor is not working properly so it doesnt activate the fuel injection.

Car will start then die after a second


Are you certain that its a fuel delivery problem? Since it DOES start and then Dies...i would look into "Cold Starting" problems.. Like a Coolant Temperature Sensor -- it acts like a choke for these newer cars. Next time you start it...rev the engine and try to keep it running for a few minutes.....see if it stays running after you get the engine warmed up....if it DOES stay running...then thats the problem. Otherwise try to get the trouble codes from the OBD2. you can usually rent or borrow them from your local Auto parts stores. Keep me posted and i can help you figure this one out.

My car wont stay running


Does the engine die as soon as you release the key, or does it run for a couple of seconds after you release the key and then die? If it dies as soon as you release the key, try holding the key for a few seconds and see if it will stay running as long as you are holding the key (the starter will make a grinding sound while holding the key but won't hurt anything). If it stays running while you hold the key then dies when you release it, that indicates that the ignition switch is bad.
