No start and raw gas coming out of down pipe

[illgetyou22]

This one is kind of stumping me, I bought this truck second hand (1996 1500 with 5.2) not running and owner said truck wouldn't start but would pop over for a second on either he had let the truck sit for a year and it stopped running. First I cranked over a couple times then checked codes and it came up with nothing. Then sprayed either and it poped over for a second just like the owner said it did. I then checked fuel pump and it was priming like it should so I took the fuel line off and found no gas coming out. Found out the truck was out of fuel (tank was empty) put five gallons in and reprimed the fuel system. When I went to start the motor started then locked when to start again and starter would not turn motor, I waiting 5 minutes tried again truck started then motor locked this time I realized fuel coming out of the down pipe. I pulled the plugs and some plugs where soaked and some where dry. Anyone have a clue what could be going on?

Sounds like fuel injectors stuck open on some cylinders flooding the engine so it won't start. At this point they probably are beyond cleaning.

Is this common? does anyone know if 10v injectors from the same year truck are the same? I have some sitting here.
