I was driving from a stop and right before it changed to third gear, I had a backfire and truck cut off. It has been 2 weeks and still doesn't crank over and I have changed spark plugs and wires, distributer cap, ignition coil. I have fuel coming out TBI injectors and even tried starting fluid and still nothing. I have also cleaned every ground wire and checked if wires were good and not busted inside.

Hello, you said your vehicle won't crank over, do you mean it will crank but not start? Or is the engine not turning over at all? You mentioned fuel is coming out of the Injectors, so I will assume it's a crank no start condition. Have you checked for spark?

Here is a guide on checking for Ignition system spark:
