91' bonneville ran out of gas and now it wont stay running unless my foot is on the gas


Check TPS -Throttle Position Sensor

May be worn out

Test it --not replace-- unless it has failed a test

Also the fuel pump maybe worn out as well

TRUCK BATTERY DIES,STARTS WHEN JUMPED BUT WONT STAY RUNNING WITHOUT FOOT ON GAS


Some models have to be retaught how to idle once the battery dies, so you need to start the truck and feather the gas peddle to keep it running and do this for a few minutes, the computer has to relearn how to idle the engine.

My 1998 dodge caravan won't stay running. starts up but shuts down instantantly or when i take my foot off the gas pedal,


ok i have a 1998 durango with the 5.2L 318 engine. had trouble with a bad cell in my battery. I went out bought an optima red top battery for it 800cca. put it in and had same trouble. No start without putting foot on gas. wouldn't stay running without holding foot on gas. CPU has to relearn it's programming once you unplug it for long periods of time. mine was without power for about 2-3 weeks till i got new battery. Start with this.. first check under air filter make sure a squirrel hasn't made a mess under your air filter and it's clogging the air intake. Then pull off the lid to your injector cover ( the screw down lid coming from the air box ( with air filter in it) to "carb") make sure all your cables move freely. put that all back together and close hood. Start truck with foot slightly on gas pedal to get started. keep it at about 1k to 1500 rpm for about 1-2 minutes. Rev motor to about 2500rpm and let it die out if it will. Get out lock doors with key fob if you have it. if not make sure to lock doors. ( trust me it worked for me) let sit for 5 minutes. come back out and unlock door and relock door 3 times with fob ( if you have it ) or key if you don't have a fob. Then unlock it with the key and enter vehicle. Start truck as before and keep it around 1k to 1500 rpm again for about 30 seconds rev it up and should keep running. Mine did. I think the iac was stuck from sitting and has now since loosened up.
Good luck hope ti works for you.

Car wont stay on without foot on gas


Suspect idle air control valve. Also clean the throttle body. If its gummed up dirty it will restrict air.

Truck will not stay running without giving gas after a jump off


when the battery goes dead it looses its memory on engine settings like idle speed.. two things you can do first one is to clean the throttle bore with carb cleaner... the other is to start with foot on gas and slowly bring it back to idle... it will pick up the idle air position to keep itself running if you do it slowly... everything happens over time so as the throttle gets dirty the computer makes these adjustment on its own and when the battery dies it starts out basicly at different percentage of idle control tht it really needs because of the carbon buildup on the throttle plates
