Put a fuel pressure gauge on the Schrader connection. 41-47psi at idle, vacuum line disconnected. 35-38psi at idle with vacuum line connected. At WOT, should hold at least 41psi. Shut engine off, fuel pressure should stay near 40psi, and bleed off very gradually.

Opti will set codes for problems in the optical section.... check with a scanner. The high voltage section can only be checked on an ignition scope.
