Last week drove to gym left about an hour later upon leaving I received a phone call shut off and upon trying to restart only cranked waited about 15 min started. Went home did a fuel pressure test and appeared okay but not great. Fuel pump is working can hear it pumping the fuel upon start. I said the hell with it ordered a new Aeromotive FPR with pressure being better that before. Took for a test ride today shut off and restarted about 2-5 minutes later and only cranked like before waited about 5-10 and started. due to the fact I replaced every part possible on this vehicle over the last 4 years I'm thinking maybe optic-spark that has not been changed. I know I bought the car with 55k it now has almost 60k. There are no opti spark codes showing. I know one of the characteristics is once gets warm it will not start. How do you test an Opti-Spark?
