I believe my fuel pump is holding pressure when i went to take the gas line off, i made the mistake of not depressurizing the fuel pump and gas went everywhere, Dumb mistake on my end. If it where to be a key issue where would I began to diagnose the problem?

If the car cranks you don't have a key problem.

Starter could be an issue.

Check for spark, sounds like it could be a DME issue. You've verified that you have fuel, so spark is the next step. Could be an issue with the crank sensor as well, although that's not likely to fail especially when the car has been sitting. But then again it's a BMW and these cars don't really make sense most of the time anyways
