V6 not starting on first try!
Last week my car has been developing a problem, it used to start flawlessly every morning (sleeps indoors), but now, it wonīt start on first try when cold, i have to give a first try, just a sec, and the seccond time i turn the key, it comes to life perfectly.
I was thinking it can be the fuel pump not building up enough pressure, but now i think itīs something else. Compression is ok though, thatīs one thing not to worry about.
The car just got a full service, valve adjustment, cam belt and tensioner changed, oil change, filters, spark plugs, cleaned the injectors, fuel tank and more things.....
Is there any sensor i can check?? Idle valve is ok, has 100 miles on it.
