tbi 454 won't start and there is a black smoke help me

Glad to help! If it's firing yellow that's a weak spark. It could be a bad cap and rotor. When you cleaned it was there much corrosion inside? If so, the clearances between the rotor and cap could be off. If the spark plug wires are old they could be the problem. Is the distributor cap and coil all one piece on this? I would try replacing the cap and coil and rotor with a stock one if you can find it.

 

Is there any difference if it is raining or the truck gets wet?
