Default 2001 Ram 2500 no start has fuel and spark. HELP

Have a 2001 ram van 318. Got in it one day and would just turn over. Checked for spark was week pulled plug and they were the worst iv seen.
Replaced plugs, wire, cap, rotor, Coil and coil ground strap. Got good spark can put screw driver and get a 1 inch jump. Tested fuel pressure and its a 45 psi. though maybe injectors wre not firing so sprayed some eather down throtle body tured over and nothing. Does not hickup, back fire, nothing just sounds like the motor is cranking over. I just dont see how it does nothing with spark and eather. Checked for codes and found none. Van ran fine before. help help help

Question, how many miles is on the odometer?

My van is very much like yours. 2001 B2500 5.2L/318cid. At 108,000 miles the exhaust pipe to the manifold came apart. Thinking it was just because of rust, I had the exhaust system totally replaced. Came to find out, the CAT got clogged and the weakest part of the exhaust system blew apart. If the exhaust would not have blown through, the engine may not have started for me.

The van had no codes and this was after a good tune up.

Gave you check the Power Distribution Center? The generator and battery cable terminals in the PDC must be inspected and repositioned if necessary. If electrical arcing at the generator cable connection has occurred, the PDC stud, nut and buss bar may need to be replaced.

Also, here are a few other known things that can be a no start and no codes shown.

Since the starter motor is working and you have fuel pressure and spark I would do a compression test to verify that the timing chain has not jumped. If you have compression then check/replace the pick up coil in the distributor for that is the unit that signals the PCM as to where/when to fire the fuel injectors. The crank sensor only signals for the spark which you do have.

So you have spark, fuel pressure, and fuel injectors are pulsing? If the engine is not running then most likely the cam pick up coil is not timed correctly to the motor. If you have tried turning the distributor to change the timing you have made a mistake and messed up the injector timing. There is a notch on the distributor plate that needs to line up where the Number 1 Plug will fire at. When the rotor bug matches that spot and the cap shows that reattaching it will the number 1 plug wire over that spot then you have aligned the pick up coil correctly. Also double check the spark plug wire routing.

Will the engine start, even briefly, if you spray carb cleaner or starting fluid into the throttle body then immediately try cranking?
