So my car runs fine and starts fine for the rest of the day after the initial start in the mroning after i leave it overnight. It takes at least 10 cranks then it sputters a bit then starts. I've replaced the plugs, plug wires, rotor, ignition coil, fuel filter and have checked the main relay, fast idle valve and the water temp sensor seems good as I don't throw any codes. I'm out of ideas and could use some expertise.

edit- the only thing I can think of now is that I lose pressure from my fuel lines overnight.........I prime my lines before I start but do so only once.

 

how many miles? have you checked your timing? ign coil? idle screw on the TB?

 

check your fuel pressure
