Starting issues
Earlier this week took the 93 to the gym no problems, after about an hour or so came out started and was on my way when I received a phone call. Idling for awhile on phone then shut car off, when I went to restart just cranked like it wasn't getting fuel. I could hear the pump buzzing prior to start but was just cranking. After about 10 minutes of sitting there it started, . I then went to the gas station a filled up and upon trying to start I had the same symptoms as before and finally started after waiting about 10 minutes. I went home and checked the fuel pressure it was good but not great. with the key on 42lbs with no leak down, and running 44-46 lbs. So I figured let me put in a new FP regulator and ordered a Aeromotive adjustable pressure regulator. Installed no problems test drive no problems FP is now 48 running and ran good. Parked in the garage and went to restart and was just cranking again. Prior to trying to start I could hear the fuel pump buzzing so I ruled that out, so I waited another 5-10 minutes vehicle started no problem. I think it may be an OPTI SPARK issue how can you test an opti ? Car only has 60k and it may be the original opti. No SES codes for the opti just yet.
