My '93 sedan with 80K miles wouldn't start this morning. Last night, it was fine, now just a click when I turn the key. Lights come on, so I assume its not the battery. What should I check first to try to fix this? By the way, I had it in to the mechanic on tuesday, they adjusted the belts, checked the timing belt and just generally checked out the car for me, if you think that might have anything to do with the not starting (I can't take it back there, its four hours away). Also, I pulled the codes and only got code 231 [Fuel trim (lambda control) too lean or too rich at part load] from socket 2, #6 was clear (111). Please, help me bring my brick back to life!
