Q: Car cranking, but not staying on

asked by on

The car is cranking, but won't stay on. We think it might be the computer at this point due to a power surge with the battery.

If a car cranks and doesn’t start, I would typically check the spark and fuel, either of which could be the cause of your problem. If everything tests out ok and the truck still doesn’t start, then I would suspect the computer has failed. Have a certified mechanic test your starting problems and try to rule other possibilites out before replacing the computer.
