The problem started with "starting disabled due to theft system". Upon further investigation I got body codes b3055 and b2960. Upon further investigation I found online this to be a real problem for a lot of people due to the pk3 sensor in the ignition. The problem happened when the battery had died. I jumped started the car as per the manual instructs, drove into town "1 mile from home" left it running the 20 min I was there come home and parked it. Next morning it wouldn't start and the info screen said starting disabled due to the ft mode. Everything oint to a faulty ignition and pk3 sensor in ignition switch not allowing it to read the ECM.

The fuel pump is leaking and now will allow fuel to get from the fuel tank to the carburetor. It was parked for a few minutes and when returned to vehicle it wouldn't start. Have noticed the smell of raw fuel emitting from the vehicle prior to this incident.

I parked my car at work. When I got out of work the car would not start. The low beam lights apparently never shut off. The switches inside the car were all off. I jumped the car and drove home and found that no matter what I did the headlights would not shut off. I went to pull relay 35 and burnt my hand. It was melting and I had to get a pair of pliers to remove it. I have had this relay fail at least 3 times in the past but it never kept the lights on. They would only not turn off. Researching online this seems to be a common problem with people's car catching fire.

While driving at about 35-40 MPH my car engine shut off, wheel and breaks too and would not start again. The car was taken to a car shop to be looked at and fixed. Once the car was there it started fine and was able to be driven for short distances before the engine would shut off again. It took about 2 weeks to finally figure out it was a fuse in the engine that was not letting power through. Well, the same problem happened in 2013 summer where the same part had to be replaced again.

Driving on the highway at 70 MPH and all of a sudden the car shuts down, like someone unplugged the engine. This was the most horrific moment in my life, semi trucks zooming past me. Finally made my way to the side of the highway and had to call a tow truck, car was towed home and the tow truck guy put the key in the ignition and it started right up. Drove the car to work and it shut down again this time I was only doing 35 MPH. I waited for about 30 min and the car started right back up, on my home from work it did it agin. The following week it did it agian, took the car to a "gm" ceritified mechanic but of course they could not find a problem, picked the car up and drove it for a few days it happened again, took it back to the gm mechanic, still couldn't find anything wrong, picked it up a week later same issue. To sum it up I have had the ignition module and the crank sensor shaft and still can not locate th problem. The car is too dangerous to drive and now it's just sitting in my driveway and won't start at all. Gm really needs to take a look at this situation brfore someone gets really hurt, the car is defective.
