95 GT Won't Start

Have replaced distributor, cap and rotor, plugs and wires, ignition module, computer and starter. Car started initially after replacing computer. Drove for a while, went home shut it off. Next day went to start, started, idled long enough to back down driveway and then shut off. Will not start even with spout disconnected. Getting a code for bad EGR valve when running diagnostics. Has anyone run into this problem? It is getting tiresome and expensive replacing engine components piece by piece!! Please HELP!!!

LOL! if the comp says bad egr valve then guess what thats what it is. Lucky for you thats a cheap part. It looks like a flyig saucer (brass colered) and its on the right (facing front) of the engine by the throttle body.
