When I use the keyless starter on my remote, the car starts, then shuts off in 2 seconds
I bought a 2000 blazer lt, 78,000 miles. I used the keyless remote starter. The engine started but shut off in 2 or 3 seconds. I tried several times, same results. So, I used the key in the ignition and the same thing happened. Then after several tries, the engine would not even turn over. While I was thinking it over, the car would try to start without me touching anything and shut off again. This happened several times. Then after 5 minutes or so, with the key, the car started fine. Any hints on what I was doing wrong?
