is it acting like it's running out of gas or does it start up and die like shutting the engine off with the key ?
I asked this as I had a Chevy motor that tried to start and when I let go of the key it died ,
It took 5 years to figure this one out as the mechanics could find nothing wrong until it happened to him one day and he immediately knew it was in the distributor , the gear on the bottom of the distributor shaft where the pin runs through the gear and shaft was worn out. A new distributor fixed the problem...
I just got a 2012 Malibu, with 56k miles, from a dealership. Within the first week of owning it, I had two instances when I start the car, but it dies within 2-3 seconds. I tried starting it a few more times with the same result except it dies even faster. Then I wait a minute or two and it starts up just fine.
-->No check engine or other warning lights. No anti-theft lights. No fault codes of any kind.
-->When it starts successfully the car runs great. No loss of power, speed, etc.
-->I try to rev the engine while starting but accelerator pedal does nothing.
-->Both instances occurred after driving 10-15 minutes (enough time to warm everything up), shutting it off in a parking lot and letting it sit for about 20 minutes, and then attempting to start again. Cold starts are always perfectly fine
Dealer is looking at it right now. Last update was that they could not repeat the problem (drive some, let it sit for 20 minutes, then start). It has started every time just fine for them and throws no fault codes. They are stumped and after looking over car forums for hours, I am stumped. Any ideas?
