Drain the fuel tank 2005 Mercury Marquis

Here is how to do it. There is a valve in the injector tubing that is used to test pressure. The valve inside it is like a valve stem. Use a valve stem remover and unscrew this part. Have a piece of fuel line hose and clamp it to the injector rail stem and then run the hose to a gas can. Be careful to insulate where you set the gas can with newspapers or rubber mats. Then turn on the ignition switch to run. Allow the fuel to fill 1 gas can at a time and shut the key off. The pump needs to rest as you are moving more gas this way than the engine could possibly use. I moved about 14 gallons of gas in about 20 minutes this way including dumping the collected gas into another vehicle. Now I removed the fuel pump relay and bypassed it, but in hindsight it should work like I am showing you. My crankshaft sensor was bad and if yours is good you probably do not need to bypass the fuel pump relay.

How can I remove passenger side air bag?

Before you remove any airbag you must disconnect the battery and wait for at least 20 mins for any power going to the bag to discharge fully.If you don't,upon removing the connectors on the air you run a very high risk of setting it off.

Controls on driver's side Power seats stopped working. Can not adjust seat at all.

The motors responsible for moving the seats are not being properly powered. The issue could be due to blown fuse, bad relay, bad connections, bad switches, ad infinitum. In short, any part in between the power source (battery) and the motor is suspect. Get a hold of the wiring schematic for your car, study it, and get to work.

Want to replace LCM 2005 Mercury Grand Marquis

The Lighting Control Module can only be replaced by the dealer or by someone who has the factory scan tool. The new module has a blank memory in it. The tech needs to upload the memory from the old module, then donload it into the new module.
Sorry to burst your bubble.
