My mechanic wants to know if it has something to do with the anti theft system. He says it doesnt seem like the distributor isnt getting power. My battery is good. Nothing has been removed except the hose.

I'd say that the wiring to the crank position sensor on the front of the engine has been disturbed

this points to the teeth on the front pulley and provides the speed signal into the ECU

if the sensor or its wiring is damaged then the car won't start
