Normal
Battery reads 12.2 volts sitting and 14.1 running. Truck cranks over just fine so I don't think that could be the problem...I replaced the coil and that wasn't the problem. I've narrowed it down to something having to do with power to the ECU or the ECU itself. When you turn the key to the "ON" position, normally the Check Engine light will turn on until the truck is started. But with my truck, the Check Engine light doesn't always come on. When it's off the truck won't start, but when it comes on the truck starts right up. When I turn the key to the "ON" position, the the light doesn't light up, I can sit there and wait and the light will usually turn on eventually without me touching anything... any ideas of what to check next?
