Hi, i have a '99 ZX2 with 144,000 miles and it does not want to run. The problem all started with my serpantine belt. It blew out on the highway, and i successfuly repaired it but a week later i went to start the car and i hear a "pop" and the car died. since then when i go to start the car it idles way up, to about 4krpm, then it revs down and dies. I have replaced the MAF, but the car still does not run, although i have gotten it to idle, it idles very rough. Any ideas?

Thanks,
Patrick

Serp belts don't break too often. Can you post a pic of what is looks like, in particular the part of the belt that sanpped. Sounds like something seized up temporaily. Water pump maybe, and it may have jumped timing.

Was the pop like a misfire? Sounds like it is taking on way too much vacuum and stallng the motor. Look for a vacuum leak

Suggested Repair

Inspect for a large vacuum leak that could cause the engine to idle very high and then stall. Also consider whether an accessory such as the water pump seized, damaged the serpentine belt, and allowed the timing to jump.

Conversation Summary

The owner of a 1999 ZX2 with 144,000 miles says the serpentine belt failed on the highway and was replaced. A week later the engine made a pop and died; it now revs to about 4,000 rpm, then slows and stalls, and runs very roughly when it idles. Replacing the MAF did not fix it. The expert says belt failure may indicate a temporarily seized component, possibly the water pump, and jumped timing, then recommends checking for a vacuum leak.
