And the problem is? Posted by Ari [Email] (#2847) [Profile/Gallery] (more from Ari) on Fri, 9 Jul 2004 12:53:24 In Reply to: I have to crank the car for 3 to 4 seconds before it, Petre A., Thu, 8 Jul 2004 19:20:49 Members do not see ads below this line. - Help Keep This Site Online - Signup |
While it would be nice for it to catch faster, cranking for a few seconds is no big deal. Every car is a little different - I've got one older car that doesn't seem to even crank - it's just running. Another one always required a bit of cranking before it starts.
My opinion is that starting time is related to cranking speed and fuel pressure. Some cars take longer to get full fuel pressure up, so it will take longer to get an adequate spray pattern. Low pressure not only gives you less fuel, but it dribbles out. Cranking speed also helps - faster cranking tends to provide more compression, and that feeds into it.
I would not increase spark plug gap. Two big reasons - (1) larger plug gap is associated with DI failures. (2) larger gap makes missing under boost more likely. It's harder for a spark to jump a larger gap, and it's harder for a spark to jump under boost. Adding the two doesn't help. THis has no effect on starting.
I don't think your engine has a problem, or at least not one worth spending time and money on.
