Yesterday morning, my husband's car wouldn't start. It's odd because we haven't had any trouble with it lately. It's a 1997 Pontiac Grand Prix V6. If you just turn the key, the engine turns over, but never starts. If you give it a little gas, it'll start, but even with your foot off the gas the car starts over revving after a few seconds. Any ideas what might be happening?
The repair shop quoted $150 to have it towed in and diagnosed, but I'd like to at least have an idea of what might be happening before I do that. I've tried googling, but none of the "Car won't start" troubleshooting guides I've found don't seem to apply.
