Vacuum seal on hose to the engine came loose, fixed it, still having issues?

Asked by Dec 09, 2014 at 11:11 PM about the 2000 Pontiac Bonneville

Question type: Maintenance & Repair

I started my car to warm up, about 15 minutes later went to leave work and it was off. Checked the vacuum seal or hose came off, I reattached it and tightened the band around it. But now my car still wont stay on. Can someone give me a few ideas of what to check? My car will start, but wont stay on. Battery is fine, new plugs, oil is fine.

You may have to reset the ECM back to factory, locate the ECM and KAM fuses in the fuse box, remove those fuses for around 30 to 60 seconds then reinstall fuses and see if it will start and run.
