Having starting trouble with my 97 Sport. Just started about a 2 weeks ago. My mechanic says he has run into this before, and has yet to find a fix. If I try to cold start it, it just cranks and cranks. If I punch the throttle, it will start just fine. It seems to idle and run just fine after starting. He checked the fuel pressure and the computer for codes. Both were fine. Any ideas? I have tried good premium gas and a bottle of STP.
