my 92 chevy lumina will sometimes start and drive fine, then the speedometer will quit working and soon after the car stalls. when i try to start it up again, it will start and then die after a few seconds. after 10 or 20 times it will start and stay running long enough to drive a few miles then the same thing happens. my cousin checked the fuel pressure and it was 40lbs. also replaced the coolant temp sensor. also noticed the cooling fans come on when this happens. any help would be appreciated .:frown:
