I ran my truck out of gas and put new gas in and now when i try to crank it nothing happens. The fuel pump will not come on and starter will not do anything. I even hooked it up to a pocket scan and it didnt come on. Also the radio and lights all work.

Key on, check for ref voltage at one of your sensors, example, tps. If nothing, I'd have to check voltage and grounds at the computer.

Pin 16 at your datalink connector has to have voltage, pins 4 and 5 are grounds.
