Question about 1990 Chevrolet Corvette

2 Answers

I have a 1989 chevrolet suburban 1500, I have reoccuring problem... my mechanics can't solve. The suburban turns off and won't start, I have replaced the fuel pump, a sensor, and it works fine for about a week or so, then it wants to shut off.... the major clue, that everyone,the mechanics want to ignore, is that when I turn on my headlamps, the suburban completly shuts off, and I can't restart it.... before I would turn on the headlamps, the engine would almost die, but it would recover, now it does not even do that.... Help please, I love my suburban.... aaa has been getting a lot of my business because of this.....
