OK -- Feel a little stupid here, but after reading posts about hard to start mercs, and TPS sensors--- I bought the harness to test the tps.

How do i get at the TPS sensor plug... is it behind the vapor separator?

The tps is located just under the fuel/water Seperafor on the starboard side of the engine. It's a flat three wire plug with brown/blue/orange wires. Be sure to disconnect the port side head temp sensor before you test it and your testing the brown and blue wires for voltage with key on.
