Have you checked for a blown fuse and/or bad relay?

thank you for your reply, no fuses are blown and the relay is new as well

there is fuel pressure , there is no pulse or spark.

Could it possibly be something with the on-board security system? PASS-II? Not sure what that year had. Alot of security systems will kill the ignition system/provide no spark if it detects a problem.

the pass lock came out in 98 i believe, this headache does not have the security feature, but thanks for shooting me a thought I really appreciate all the input!
