Fist off, greetings to everyone in the forum, this looks like a great place to get info about my car.
I have an '01 Cavalier that has run great since I bought it in January, it had 47k miles on it. Car ran perfect on CNG and regular gas, nothing strange about the car.
First Problem:
Within the last month and a half the car has started having problems starting on CNG. The car would at random start on regular gas or CNG. It seemed to me like it would just skip the check process of whether or not there was CNG in the tank and go strait to regular gas. I could see the indicator light on the dash wouldn't come on for the few seconds like normal and would stay off (indicating it was on CNG) but it would run on regular gas even though I know the CNG tank was 3/4 the way full.
Second Problem:
So I am driving the car home Christmas Day and near my home the car dies and refuses to start again. It was running on regular gas, and I know it has 1/4 of a tank of regular gas but it refuses to start. I removed the battery cable and let it sit overnight, plugged it back in and tried it to see if that would make a difference but nothing. After the car sits for a little while, I can try starting it and it will seem like it wants to start but doesn't run more than a turn or two. It seems to me like it isn't getting fuel, but that is just my guess.
I'd like to fix this on my own. I have access to a full shop and some close friends that are mechanics that will let me bother them with questions, but none of them have much experience with CNG. If anyone could give me some guidance on what I should check to weed things out and narrow down what is happening to my car, I would very much appreciate the help.
