One thing often overlooked is the ignition switch and ignition relay (the one under the dash). I've had the same no start problem on a few of these cars and it a couple of cases it was the relay and one it was the ignition switch (actually the plug for the switch was damaged)and more recently I had one that had the harness pinched between the battery tray and the bottom of the under hood fuse box, shorting out the ignition wire.
Another thing overlooked is the alarm system (if equiped). When I get one with a no start condition the first thing I do is rip out the alarm (if equipped) and restore the original wiring. 9 times out of 10 and alarm system is the no start problem.
