My 1990 Honda Accord LX, 4 Dr Sedan, manual trans. won't start. I recently replaced the timing belt, battery, alternator. When I turn the key in the ignition, the red dashboard lights come on (including the yellow CHECK ENGINE light, which goes off before the others). I hear one click (not three) and some faint whirring under the hood). But the starter doesn't start. I tested the starter at Advance Auto and it works fine. A know power is getting to the starter and the fuses under the hood seem fine. I've been reading about Main Relay solder expansion in heat, but it's Winter and it hasn't been hot. The car ran fine just this week, with no indication of any problems. Any ideas? (I'm not a mechanic. I'd really appreciate it if someone would tell me where the Main Relay is in this model.) Thanks.
