motor wont fire.

[mustangracer71]

Truck stalled out, found out AC compressor seized up, prevented from turning over, installed bypass pulley for now, turns over now but wont fire, fuses good for fuel pump, can hear fuel pump turn on, theft light not on. I'm 100% stumped!!!! PLEASE HELP!!!!!!

did it snap the belt? if it did it may have taken a sensor out with it

Just because you can hear the fuel pump doesn't mean it is getting fuel. Check the basics - air - fuel - spark. One of them is missing from the equation.

Check fuel pressure.
Check the connector on the crank sensor.
Check for spark - keep an old plug and wire for this or use an inductive timing light
