I’ve replaced the rotor, distributor cap, wires and plugs and the crankshaft position sensor and still no luck. The codes that have been surfaced are 35, 47, and 63. The fuel pump primes and there is gas at the rail. I’ve looked through all the fuses and they are all good. What the heck do I do?

The next logical step would be to replace the coil. There is a chance that it is hydrolocked, aka flooded too. The fuel pump primes every time you turn the key on. If there is too much fuel pressure, it can keep the pistons from moving at all too. If you get spark and it won’t crank, then remove the plugs for a few hours and let the excess fuel evaporate. Good luck.
