I would be more suspicious of the new air filter. Why not put back the original air filter, housing, and hook up all the hoses ... and see how that turns out?

actually the k&N filter was juts a stock one, everything is stock all the housing hoses everything, what do you think it could be?? that totally threw me off dude i have no clue

the same happened to me this past summer we traced the problem to be the fuel pump relay (Green) and we also change the coolant temperature sensor now it starts just fine

[dsastr_clan]

really??? is that relay located behind the battery in the small black box?

Take a look around the oil filter and make sure you didn't knock a vacuum hose loose somewhere. Also check the one that connects from the rear of the valve cover to the bottom of the air filter assembly.

k what? did you mean to hit e? Think back to all the different things you touched when you installed them parts. Now go back to all those areas and look for disconnected or dry rotted vacume hoses.

Also, punctuation is your friend, and mine too.
