That won't matter if he disconnects the compressor and it still does it.
Also the water pump and ps pulleys should spin with very little restriction. They should feel about identical to each other. When you crank it with the belt on does it slow down the cranking speed or does it sound the same?

Possibly. If you have a problem after a repair always follow the KISS approach. Keep it simple stupid. Double check all your work. I doubt the belt is pulling the compressor any tighter than the bolts unless you didn't tighten them. But it is worth a check

have you tried a belt without ac? Like get a belt that is for a non ac vehicle?

you can't unless you change out your belt tensioner. to run it without the ac the tensioner has to push down instead of pulling up like it does with the ac due to the way the belt is ran. trust me I already looked at that possibility.

A 330ci engine should be powerful enough to overpower any given pulley on the front of these engines (especially with the A/C disabled). Resistance from any pulley (which you don't seem to have) would just cause a belt squeal and maybe cause the tensioner to flex tighter than usual.
Given that the engine almost refuses to start under any kind of a load, I gotta believe you have a bigger problem. I hate to be the pessimist, but what you describe sounds like an engine problem. I am not necessarily suggesting engine failure ... you should start with the pieces that feed the engine what it needs to run and if you can't find any issues there, you're gonna be looking deeper into the engine. I see this thread has gotten quite a few responses, so forgive me if some of these suggestions have already been made, but I would start going thru the following...
After all that...if you still have issues you have to start probing deeper into the fuel system. Adequate fuel pressure? Injector issues (time for some SeaFoam)? Then unfortunately, you have to start considering pre-engine failure conditions exist. Inadequate oiling...sludge...etc., can certainly exhibit the problems that you describe.
I sure hope you find a bad FDPM or a clogged fuel filter!

I see this thread has gotten quite a few responses, so forgive me if some of these suggestions have already been made, but I would start going thru the following...
- Intake - Make sure there are no air restrictions. A good test might be to completely remove the intake tube (factory or aftermarket CAI) and let the air free-flow. I wouldn't do this in a dusty/dirty environment though. Maybe just be 100% certain that there are no air flow restrictions at all...consider a new filter, etc. and retry with certainty that there are no air flow issues.
- Exhaust - Typically a clogged CAT or exhaust system will cause codes to be thrown in the PCM; however, my guess is that may not always be the case. If your exhaust system is very rusty, you could have some exhaust flow restrictions that incumber the engine under any kind of a load.
- Fuel System - Check your FPDM if you haven't already. Their failure is a very, very common issue and if you have the factory-original FPDM, it could very well be causing fuel delivery issues. Fuel filter would be the next easy place to look. If you have never replaced the fuel filter, and you don't know if previous owners did or not, chances are it really needs a fuel filter.

so I jumped under the truck today undid the bolts to the a/c compressor and presto I see the wire from the crankshaft position sensor was indeed pinched and bare wire was showing.. checked the wire to make sure it was intact, threw some electrical tape on it repositioned it and put the compressor back on, put the belt back on and boom the truck starts up no problem. this was the fix in the end. I hope that this can help somebody In the future if they run into this problem. I want to say thank you to everybody out there that has helped me with my problem.
