Hi, I'm having some problems in starting my 90 Civic HB. The first start up after it's been sitting awhile (ie. overnight) no problems, cranks, starts, good to go. If I park it after it's been running 5/10 minutes sometimes it's doesn't want to start. No crank, clicking under my dash. Wtf!! Today first thing in the morning, start up, no problems. A couple short trips, without any problems. Now I parked my car for about an hour it doesn't want to start. No crank, clicking sound from a relay(?) just above my hood release, and it sounds like my starter motor is making a sound. I tried boosting it, thinking maybe my battery had a few dead cells. I replaced my starter about three months ago with a new unit. Any ideas? I'm going to the junkyard in couple of days, hopefully aquire a handfull of main relays, a starter motor, and whatever else I can think of on what the problem could be. I heard the main relay is a common problem for this era of Civics.
