So I tried to turn on my car when i got back to the parking lot and it wouldn't start. I let it sit for about 20 min and it started, so i was driving and it died on me, so i pulled in a gas station and bought a battery from kragen next door. After about another 30 min i put the new battery in and it started so i drove and got stuck at a light 5 min later. My mechanic looked at it today and said the engine is not saying there's a problem at all. He thinks it might be the computer system itself, which i guess pretty much screws me. It sounds to me something is telling the engine to kill after a short time, but i'm not a mechanic. If anyone knows what it might be or has heard something like that please reply, thanks!
I had the same problem drive somewhere perfect got back in car would not start but I had full power radio, lights, phone, etc. Sat for 10 minutes started right up no further problems. Called dealer ship they replaced some sensor and was good for a year than same sensor went bad fixed it again and no problems since. They told me it was a shifter sensor but I'll see if I can get the exact item from my old bills.
oh ok great thanks for all the info. I talked to the mechanic today and he still doesn't know what's wrong, so i told him about the sensor and said he'll replace it but not sure if it's the problem b/c the system isn't saying there's a problem. I'm 99% sure it's the sensor so i'm going to have it replaced and hope that works
It's close to the oil filter, kind of hard to reach. you need a torx socket to remove it. The connector is in the back if the engine near the fire wall. Search this forum for more details, some did a nice write-up.
