[QUOTE="baldguy, post: 15510835, member: 179649"] I'm bumping my old thread since it has all the same info I would need to re-type to give you guys some background. Anyway, A new fuel pump did not help my issue. Also the PATS system is not engaged. I have discovered a few new things that might help some folks smarter than me figure this out :). The biggest thing is that the plugs are wet with fuel after a day or so of sitting. I noticed this when I decided to change the plugs, and when I put the new plugs in it fired up faster than any car in the history of cars has ever started. Barely turned the key and it was running. I thought I had it fixed! I was wrong. a couple of days later it was back to the exact same symptoms. so now, I know i can pull the plugs, let all that fuel evaporate, and it will fire right up. if I don't do that, it refuses to start. This really sucks for a car that only gets driven a few days per month. I have replaced the coils, the fuel pump, the fuel injectors (brand new 47lb FMR), the plugs, the wires, the battery, put a new tune in it (for the full offroad bassani exhaust), and it still acts the exact same way it did before all of that was done. When it runs, it runs fantastically. It will idle smoothly all day long, pulls hard to the redline, and never stumbles or complains once it's running. I'm convinced it has something to do with the fuel that is building up on the plugs (and in the heads) but for the life of me I can't figure out why that is happening. Even my trusted mechanic is a bit lost on this one. But it's perfectly repeatable - it won't start unless I go pull the plugs and wait about an hour then put them back in. then it fires up like nothing was ever wrong. please help! I love my car, I just need to exorcise this demon and we can go back to being best friends. Thanks! [/QUOTE]
