Question about 2007 Chevrolet Cobalt Coupe
I have about 33k miles on my car. My car shut off when I pulled up to a stop sign last friday night. When I tried to turn it back on all that came back on was the lights. There was no engine turnover at all. No sounds were coming from the car. I didn't have any indications that there was anything wrong with the car. It didn't hesitate when I drove it earlier that day and I haven't had any other problems like this with it. The only other problem I've had was with the clutch and that's been fixed. There is one thing that I have noticed but I wasn't sure if this had something to do with the car or the quality of the gas (watered down gas maybe?) I was putting in my car. I've tried to go to several different gas stations but I still seem to be going through an insane amount of gas. It, sometimes, takes an entire unit (out of the 8 units on the gas mileage tracker on the dashboard) to commute back and forth to work for just 1 day - and it is only a little over 11 miles both ways combined. Do you know what could possibly be wrong with my car? It is with a chevy car dealership but they're stumped at this moment.
The first thing i would check into is the coil packs. If it sounds like a missfire (hard to hear on a small 4 cylinder). Also it sounds odd but the engine sometimes has an ignition fuse. If that fuse is blown there is a power wire short somewhere in the wiring harness. Also if the check engine light is on the gas consumption may be the O2 sensor. I have had sensors last for as little as 200 miles before on my truck. This dropped my mileage from 21 to 4 mpg.
