97 C1500 Not Firing

[cfmetal16]

I have a 1997 GMC C1500 with the 5.7 motor.

 

I recently pulled the gas tank to patch a hole. I reconnected the tank and all wires (double checked to make sure wires and hoses were reconnected properly). I go to start the truck and it would rotate but not start.

 

I pulled the filter and started the pump up and it was pushing gas through the system. I replaced the filter with a new filter. Engine would still not fire.

 

I pulled the ignition coil and brought it to get tested. It tested out fine and while I was at the auto parts store I picked up a distributor cap and rotor.

 

Got home and reassembled everything and it would still not fire.

 

Any ideas?
