I have a 1999 murcury Mystique 120.000 that was given to me. it has been siting for two years in a garage. I think i have done all the nessesary jobs to get it road worthy (Fuel pump,battery,new gas, new battery terminals,new tires) I am having a problem geting this car started now. I am losing power some where. when i try to start this car the starter just clicks and all the lights in the car dim. Is it the battery? Do i have a short that drains the battery?
