lots of codes... advice on where to start.

[Jaegze]

Just to regroup I wanted to run through everything I have done with this.

Started off testing the fuel pump. I got the fuel pump test kit from parts place and hooked it up. The first time I didn't get a reading. I ended up leaving for a bit came back and read it at 55 psi. So I assumed the pump was good.

I checked spark with an inline tester and got a strong light.

I replaced the cam sensors, maf and CPS. I replaced each one one at a time with no change in the way the car acted. The intake cam sensor when I took it out, the outer casing was off the sensor and when I pulled that from the hole the outer casing was broken. Wondering if something could have happened inside of here?

I took out the ICV and cleaned it, it wasn't too bad when I took it out but cleaned it anyway and put it back in.

The car will crank but will not fire. When I push the throttle to the floor the car will sputter a little bit on and eventually may run a bit on its own but then backfires and shuts off.

Going through and randomly checking things I took the disa valve out. The car will start up with it out but will loudly backfire and shut off.

putting the disa valve back in returns the car to a no start with sporadic firing as described above.

The intake boot is in good condition and I check the vacuum lines around the car a couple of times and replaced things as needed.

I guess I'm kind of stuck moving forward as I don't know where to go from her with this thing. I may have to take it to a local garage. No BMW mechanics or shops within 90 minutes of me so it would be to an independent shop. Im not familiar with the vanos valves. Could this be an issue? Ill search a bit but I have never had to mess with them.
Thanks again for the help!

I do have to do the smoke test yet. Which will be my next step, unless theres a better idea.
