Why do people feel compelled to start taking things apart???

First, buy (borrow) a timing light and check for spark at the distributer center wire.

Next check for fuel pressure.
My '91 has a test connection on the fuel rail, anyone with a '96 care to check if they were still there on that model?

Report back results.

As for ignition coil, try to get a look under it for burned marks where the high voltage wire attaches.
