I have a 1995 Cutlass, 3.4 DOHC engine, 75,000 miles on it. It starts fine when the engine is cold. When hot, it sometimes will crank fine, but will not start. Sometimes extended cranking will get it to start. If I do get the hot engine started, it runs fine. Other times the hot engine will start with no problems at all. Does anyone have any troubleshooting advice they can share? I would like to diagnose the problem so I am not blindly replacing parts.
Ok so i have decided i would like to do a pulley swap on my gtp, I have been told from a buddy who has a gen 4 that i should be able to run a 3.4 pulley. This is after swapping to stage 2or 3 colder plugs and swapping the 180 degree thermo. Now has anyone else done this? Was also thinking maybe the 3.5 Pulley instead. Looks like ZZP has a pretty decent deal for there modular setup. Any info would be greatly apprecited.
