sat for a little over a year. put new battery in and all electrical comes on but not a sound when I turn the key. I want to start with checking the starter. Any little secrets that I should know about before I dig into that area. I just bought the car, so I'm not the one who let it sit

Answer #1patrick mannion from Greg Solow's Engine Room, June 24, 2011, 01:29Master
The engine has standard Bosch electronic fuel injection, key on should have 12 volts at one side of the injector, the engine has multiple ignition coils again should have 12 volts at one of the wires at each coil, control module will trigger the coil to ground to operate it/ create spark. A car that has sat may have been parked for any reason and often people honestly forget the problems (or all the problems they had). Look for rodent damage to any wiring, look for mouse droppings, around the engine compartment, look for a mouse nest in the air filter housing. I had a Jaguar one a mouse ate a fuel pump wire at the back of the car and some fuel injection computer wires under the dash took quite a while to locate exactly what wires were causing the problem. With car in park, e/brake applied give power to the starter (by passing the starter) see if engine turns. If its a car you just bought and obviously need information on, There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
You will like Alldata information is out of Mercedes manuals but even they are sometimes hard to follow.

I believe your right on the money with the starter.
sitting so long could have corroded the inside of the starter solenoid.
If you can get a voltmeter , have a helper hold the key in start, & then check the tiny wire at the solenoid for 12 volts.
The big top wire has 12 volts constant, but the tiny wire on the face of the solenoid is dead until you turn the key to START. Make sure you have 12 volts when the key is turned.
IF YOU HAVE 12 VOLTS THERE , Then tap on top of the solenoid with a solid object like a small hammer.
PLEASE BE CAREFULL,
Not to have your hands or clothes near the belts or pulleys if if suddenly starts.
