I had a good spray of gas comming from the reg....didn't notice any fuel vapors coming from the vac line.........it is still hard to start when it warms up for 5 min........but runs fine no hesitation or stalling, when it finally starts...can run it and accelerate hard.....no problems

Thanks Jim

Hmmm, this is a good one. Question, is it an extended crank first thing in the morning? or how long do you have to let it cool down before it starts normally? (this is important)

I had a cold start problem on a Lesabre and it was the coil packs, but yours is hot so I'm not sure if the coil packs would be an issue?

It starts right away when I first start it in the morning.....I even had someone stand behind the car and look when I started it when it was warmed up, after a few extended cranks, it fires........no black smoke from flooding and no white smoke from internal coolant leak......a little worried after reading the forum about upper intakes.....

I have tried it 1 hour after shutting it off.....engine semi-cooled off and it still hard to start. Turn it off for 1 min ........it starts right away

Jeez... those are the exact symptoms of a leaking pressure regulator -- the restart after 1 minute is easy because it hasn't had time to really pump the vacuum line full of gasoline -- so if you've already verified that the vacuum line at the regulator is dry, then I'm stumped.
