Any ideas on why my 90 won't start? It's been sitting for about 3-4 months, and with a brand new, never used Optima battery, the thing won't turn over. One click is all you get when you turn the key. I beat on the starter and even tapped on the solenoid, and still one click. I ran out of time to check for voltage at the starter, but is there anything I'm overlooking? Maybe a relay or something????? Oh, and the car has had two starters in the past three months that it was running before I parked it. Give me some ideas you guys! Thanks
