My mother-in-law has a Ford (sorry, don't know model/year). While she was running errands the air-bag light stayed on while she was driving from point A to B, then worked fine (staying on for only a few seconds after starting car) from point B to C and thereafter. Is this a loose wire of some sort? Any help would be appreciated. Thanks!

Thanking you in advance. My 92 Buick Riviera (auto, 3.8 litre) will not restart once the engine is hot. If I start the engine cold, drive for 5 or 10 minutes, no problem restarting. If I drive or let idle for more than say 10 minutes it will not restart. If I then let the car cool for 45 minutes it will restart every time. The car is cranking fine it is simply not getting gas because when I have released the fuel from the nozzle in the engine the fuel line will run dry but the fuel pump will not kick in when I crank it again. It almost seems like a vapor lock however, when I had the car in the bodyshop they put it in an oven at 140 degrees and the same problem happened even though the engine was cold before it went in. There are no engine codes showing and a diagnostic showed nothing as well. The problem began this spring once the outside temp got back above10 degrees celcius. Any direction will be welcome. Mike
