GL450 WON'T START
I replaced the air pump on my X164 and after I started the car, it ran for a second or two, I heard a noise under the hood and the car shut off. Afterwards, the car wouldn't start. Dashboard lights work, fuses look good, and starter is good. What would cause this kind of error?

First, double check your work and make certain that all hoses and connections are as they should be. Check everything that you touched (battery connections, fuses, belts, etc.), not just the air pump.
Then use a code reader and post the codes to this thread. It will provide a better starting point for further troubleshooting.

I uninstalled the air pump and reinstalled it but nothing has changed. Moreover, I can't get an OBD reading without the engine started. I'm thinking it's the Crankshaft Position Sensor, so I've ordered one.

OBD readings are available with ignition in position 2 (0 = off, 1 = accessories, 2 = on, 3 = start). You do not need to start the engine to read codes -- this is DIY 101.
