show me where the transmission stick is at

I replaced the crankshaft position sensor and the fuel pump. Still my ML430 will not start. It cranks and it sounds like it is going to start, but dies instead. It has been down for two and a half months. It was in a shop, but they couldn't even remove the faulty crankshaft position sensor so I brought it home. How do I get the engine to start?! I need my truck.

i change the auxillary water pump because it stop working but it seem like air got caught in there and i cant get heat when i am driving only when i am not

THE PROBLEM HAPPENS WHEN I TURN THE HEAT ON AND I AM DRIVING BUT WHEN I LEAVE THE CAR ON TO WARM UP I GET SOME HEAT

THE PROBLEM HAPPENS WHEN I TURN THE HEAT ON

driving and its running what is the problem

When putting car in drive rpm doesn't move and car moves slowly forward and in reverse. But rpm goes up when in park or neutral.

After maybe 10 mn or so I've lost so much fuel pressure that I have too crank n crank too get it restarted n I've changed the fuel pump just yesterday as well - What do I do next? N the same problems occurs constantly - yesterday when I changed the pump I had 0 lbs of fuel pressure at the check port in the fuel rail
