Plugs, coil, wires.<<<
Time to get testin. Are you getting no spark on all cylinders? (i think coil)+(distributer) Take it to a shop and have them check that out. Its cheap and easy to check.
Congrats on the $1000 buy good deal, wish i got it!

I could be a ECU problem. There are capacitors on the ECU that I have heard will go bad. There is no distributor/coil like shadowboy suggested, but there is a coil pack for each cylinder. Have you checked each plug for spark? I don't know if the stealths had a switch on the clutch so the car cannot be started in gear, if it does that could be a problem, like I said, I don't know if that is on stealths or not. I think there is a cam angle sensor as well as a crank angle sensor. I have read that if a car jumps time the cam/crank sensors won't allow spark, but at this point I am really just speculating as it is easy to do armchair troubleshooting. Good luck, let us know what you find out.

I just sent my ecu out to have the capacitors replaced. I was not getting fire on cyls 3 & 6. paid $200 in diagnostic fees, only to be told that a non-rebuilt ecu installed would be $400 more. found a place on the internet that charges $20 diagnostic fee, then $139 rebuild fee. Hope to have it back in a couple of days. Will report back then. The ecu is easy to remove. this website sugests disconnecting the battery before removing ecu. also, says to inspect the board for burn/scorch marks, bubbles, ect. if none of these are present, chances are it can be rebuilt. anyway, here's a link to the site:
