Those are super fouled up, which makes sense from how you're describing what it's doing.
-Fresh plugs, throw some NGK TR6's in there, they're cheap, if they foul up again, who cares
-Make sure all the coils are good if you mentioned one was broken
-remove the fuel pump relay in the fuse box (or fuse) and crank it over, you should get a good idea if it sounds smooth turning over, or if it's clanking like a rod is swinging around loose lol
-make sure the battery is good. I've seen piss poor relocation setups with good batteries have a bear of a time starting from weak voltage at the pcm. Truck would crank and crank and crank but not fire up. Then it'd crack and bang and foul plugs up real bad. Redid the grounds on the shitty relocation kit and bam fired right up. Another reason why I built my own relocation kits to eliminate that crappy type work but that's aside from this lol.
Also make sure the fuel is good if it's been in there a while, may want to drain it out and put fresh in. I've also seen trucks really acting up if they've had race fuel sitting for ages then try to fire up.
