Are you getting absolutely nothing? I mean, it's not even firing at all? No backfires?
I guess if it were my truck I would
1) Put the #1 piston at TDC of the compression stroke, and ensuring the timing lines up. Maybe you've done that already. Might be worth tripple-checking. I can't remember (sorry) if you did anything with the timing. Disregard if you haven't..
2) See if there's spark at the plugs. Are the plugs wet at all?
3) Test for fuel pressure.
4) I would test the crank and cam sensors with an ohm meter. I know you have new ones coming, but you could test them today yet. Make sure the scanner is giving you a 'good' on those sensors. In other words ...the computer is "Seeing" the sensors function.
5) Ensure the fuel pump is operating (I think you said it was...but I don't remember). Obviously you need proper fuel pressure.
5) Wiggle the key as you try to start it. Try starting multiple times. I'm guessing you've done this. In case the WIN module contacts aren't contacting.
6) If you are sure of the timing, have good fuel pressure, Crank & cam sensors seem good, engine grounds are good, all your wiring seems good, don't have spark and everything looks dead, I would maybe revisit the WIN module, and/or dig into the TIPM. And/or check critical wiring from the crank/cam sensors to the TIPM (in case one got pinched/corroded). There have been guys on the forum who've had to chase shorts in engine wires ...one by one.
TIPM: There were known TIPM (the computer) weaknesses on those early Rams. Most of the issues were associated with the fuel pump relay. So if your fuel pressure is good, then I'm not sure if the TIPM would be at fault. That's why it would be good to check the fuel pressure. There's also the fuel pressure regulator back by the brake booster. But if fuel pressure is good, then...maybe those aren't the issue. If it's poor, a guy can bypass the TIPM f/p relay, or swap out that relay for another like one on the board. If you considered 6-starts a day for 23 years that's 50k+ relay starts. New ones on ebay (
HERE) are not much. Or, maybe somehow the board got cooked in the process of your work. Doesn't seem likely. Again, ya hate to start thinking 'computer'. Maybe wait for the cam and crank sensors to arrive, and if nothing there, ...then ensure wiring to the TIPM and/or later, perhaps consider the TIPM. See some info
HERE. Are there any relays in the fusebox that would prevent it from starting? Just thinking out loud here.... throwing ideas against the wall.
I know how frustrating it can be.... Been there...
