Engine spins, no fire, no start

Pickup was parked for about 3 years. I decided to get it running again, needed to replace gas tank cause I hit a rock and put a hole in tank when I parked it so I replaced tank and pump. I started it and it ran but when I checked water there was no water but I didn't run it long enough at do any damage. I put water in only to find out the head was cracked so I had to take head off and replace it with a new rebuilt. I then put new injectors in it as well as lifters and push rods. Started it and it ran but #4 cylinder was dead. Had spark but it was missing on #4. I took wire off to find out. Ran the same with wire on as it did with it off. I did a compression test all had around 150psi. I replaced #4 injector again, but now there's no fire. I replaced crank sensor, cam sensor, ignition control module, replaced timing chain and gears, replaced coils, replaced ignition switch, put a different engine control module, wouldn't start so I put original back on, checked all the grounds, grounds were good, check wires on the ICM, has 12 volts and ground is good but the signal wire doesn't show 0 hertz with just the key on and cranking its all over the place. This is with new ICM so I put old ICM back on thinking maybe I got a bad ICM still same voltage. I checked new crank sensor thinking maybe I got a bad one but if I check it out right it works. I've wiggled wires, checked wires, found 2 wires buy the gas tank that were broke I soldered them together and still didn't start. I've checked fuses about 20 different times. When I first worked on this thing I was using my battery pack cause I didn't want to buy a battery tell I knew it would run. I have since then put in a new battery. It ran fine when I parked it, it ran before I replaced the head and after. After I put new timing chain in and before I put timing chain cover on it started but I shut it off right away. Put cover on and it wouldn't start, no fire. Then I thought I would take crank sensor out and check it, when I took old sensor out I broke it and by the time I had it out I damaged block somewhat so I put a little silicone around it so it wouldn't leak so I thought maybe I wasn't careful enough and got some on the end of the sensor and there was very little on it, I cleaned it off put it back in and it started and it ran for about 25 - 30 seconds, it stopped on its own, and now it don't start again, no fire. I'm to the end, other then a broke wire or something not making contact I'm lost. Check engine light ain't on and there was one code had something to do with EVAP to much pressure in tank, that had to be an old code cause the tank leaked so how can there be to much pressure in tank. Only other thing with new fuel pump in tank and sending unit my fuel gauge isn't showing right. Shows full and it's probably 1/4 -1/2 at the most. As much as I know pump is working cause there's pressure on the schrader valve on the fuel line. Gas shoots out when key is on. It's like it has got spark when ever it wants to and starts and stops right away.
