2000 Chevy Monte Carlo Shut of while Driving...

Hello, is the vehicle running? Can you check for codes? Some of the national brand autostores will check codes for free.

If it cranks good but won't start, you can have a helper crank it, while you check for spark at the plugs and fuel pressure. My first thought always goes to the rpm signal,but, you never know.

It does run, it does not happen all the time. It is just starting to really annoy me. I spend 4 hours this morning going through all the electrical wires that I could reach and see. I even replaces a few of the fuses and installed new relays.

I'd still check for codes, intermittent stuff can be hard to track down. You need to do testing while problem is ongoing.

ok will do thanks for all the help. Will repost when I find the problem so that others with same problem can have a reference and diagnostic to refer to...

While driving my car it suddenly shuts down like shutting car down. I have replaced the plugs, plug wires, and checked all fuses. Alternator is good and Battery is new. Have gone through all that I know. Would like to know if there is anything else that I can do myself or take it to a dealer.[/quote:56e0f458fd] I also have a 2000 monte Carlo S/S and it did the same thing. I fought it for weeks. It would seem fine for a few days and then start dying at stop lights. Most of the time it would start right back up, but a few times I sat for 15-25minutes. When I would come to a light Id put it in nuetral and rev it some and then throw it into gear. I had it tested at autozone several times and the same code came up. I forget which one , but it was wrong. I did everything that I could do , talked to people ,read these types of forums etc. and one day I unplugged the mass air flow sensor and it actually solved the problem. I went to autozone, left the car running and removed the mass air flow sensor and bought a new one it was like an [80.00] core charge. Installed the new one and my car died and would not restart. I unplugged the sensor started my car and went in and got a refund. That was a year ago, and Ive had no problem since.I would like to take it to a shop eventually but just dont have the money. I dont think that its really affected my gas mileage much but would like to somebody quallified to give me a proper explination. I am a plumber by trade and I often tell people.... If it aint broke , dont fix it!!!! So my wires just hang there and the car runs great!
