Having the same problem with a 2002 SC2. Changed everything so far. Car powers up when it feels it wants to. Checked everything. Changed battery, alternator, Starter, cables connectors, list goes on and on. Every once and a while it'll happen but the car will work for about a month or 2. Then just like that won't start. The funny thing is my gf will be using it all day and it just will go on her. No crank over no turn over no nada. No stupid chime. No lights. Thankfully its our 3rd car but so nice on gas and a great commuter. Its 5spd. Also changed relay switch and igntion in the steering rack. Worked for 2 months then same problem. Been following this forum for a while and all inquires made have been very helpful. Make matters even funnier (and worse) i'm a manager at a high volume body shop. My techs are puzzled and dont even wanna help me work on it (not that i blame them). I've been looking for the electric relay diagrams and what not but anyone in the bizz knows that those books are like gold and no one wants to give them up for an hour. Gonna try the "thingamabob" next see if that helps...if not back to square one. or we could just burn it and get the $500 from insurance lol jk
