98 PCM Bad?
OK im kinda lost here with this car i just bought... It is a 6.0 with 243 patriot heads. Theres fuel and theres spark but it doesnt start. Vats are deleted, Cam Position and CRank position sensors are both new but it just doesnt start and smells really rich. What you all think it could be? Bad PCM? Im not sure whats missing. Please help with this headache

So from what you're describing, sounds like it's dumping fuel. Any codes being thrown? Also, since it was not running when you bought it....what did the previous owner say happened?

The previous owner said it was running fine then one day it just stopped. I flashed the CPU and its a completely stock file. And yes its flooding the cylinders. Till i forgot to mention that i charged the oil and i noticed there was gas in there too. And i also checked the timing dots and they were aligned perfectly.

Any trouble codes showing? That's the next logical step. Also, what's the coolant temp sensor reading when you scan it?

Hook a pressure gauge. Open the ignition key and let the pump prime. Don't crank it.
With key still open, watch if the fuel pressure goes down. If it does, you may have leaky injectors, bad wiring or faulty PCM.
