Question about 2005 Chevrolet Malibu

1 Answer

2005 Chevy Malibu starts but only runs for 5 seconds

My Malibu starts up fine but only runs for 5 seconds. If you hit the gas it boggs out and if you dont tough the gas it dies too. I pulled the gas tank and took apart the fuel pump and cleaned the dirty fuel filter but it didn't help. I replaced the battery and had the altinator checked and it is fine. I was wondering if it could be an electrical problem. What is the proper ohm reading for the coil pack? What is the proper fuel pressure at the fuel rail with the key on? I don't want to put a $400 fuel pump in if it isn't the problem. Sensors might do it as well too right? HELP PLEASE !!!

It sounds like your air fuel mixture might be off by a little bit. The problem may not be in the fuel lines but the injectors theselves (if it applies. Hard to tell when the carburetor went out of style now a days) I would try to clean the injectors with a fuel cleaner and also to consult a Chilton book. That there is $15 of worth it. It will tell you all you need to know. If not then you could always contact a dealer and they will order you a service shop manual on that specific make, model and year.

check the fuel pump pressure you might not be getting the amount of fuel your truck needs to keep running an easy way to check is to tap the gas when it starts to bog if it picks back up thats what the problem is.

2001 chevy malibu wont start after the car runs out of gas and we put more gas


It may take 3-4 times cranking for a few seconds,
with a 5 second pause between to get fuel up to the engine. Also may have sucked up
some dirt/debris into the fuel pump after running it dry. May want to change fuel filter.
you can try to have someone bang on the bottom of the tank while someone else
cranks engine. Sometimes this will free up a stuck fuel pump. good-day!!

Is there a fuel switch when you run out of gas


after you put about 2-3 gal. of gas back in tank you should turn key on for about 4-5 seconds then off then try it again to get the gas back in the line.
if it don't start after trying that it could be you burned up the fuel pump in the tank.
when you first try this have someone listen for the pump to run at the tank.
take off the gas cap and listen from there.
when you first turn on the key it should run for a couple seconds.

No fuel in motor. will not start


when you turn the ignition key to the on position you will hear the fuel pump run for 5 seconds.
if not heard replace the oil pressure switch for the third wire on that sensor runs the fuel pump the first 5 seconds to start the engine. once pressure is operating at normal conditions the relay takes over on the pump to run

2005 Chevy Malibu starting problem


sounds like its a gas problem. i would normally say its the pump but if you replaced it already then its not likely. i would look and see if there is anything in the tank clogging the pump. something may have got sucked up in there while you are turning.
