When turning the key, it tries hard to start buy won't turn over. We have replaced the throttle body sensor, fuel pump, all new spark plugs, and two new engine coils. It also has a new SDM module that was just installed as well. The battery won't hold a charge either. We are not able to jump the vehicle either with our other vehicle. What else could we do to get this car to start?

I am not sure what you are saying here, the engine cranks over but not running, or the engine is not cranking over? Can you upload a short video of what the engine is doing so we can help you fix it? In the meantime, here are two guides to help us see what's going on:

Please run down these guides and report back.
