motor turns over but wont start. has fuel pressure. checked relay, sprayed b12 in breather; tried to start but did not. maybe ignition coil pack???
First check for fuel press with a test guage, if there is pressure then test for spark with a spark tester, you can buy these tools at most auto parts stores, some will loan them to you free of charge like Kragen. Get back to me with the results.
