A while back, I posted that I have been having warm start up issues. Namely, when I start the car for the first time of the day everything is fine. However, after the car is driven then turned off and sits for over 30 minutes it does not start on the first crank. It starts on the second attempt, idles rough, I hit the gas and everything is perfect.
I tried a plethera of fixes to include: Clean ICV, Clean throttle body, Check DISA, Replace all plugs, Vanos rebuild, Intake boot replace with silicon Stett boots, CCV and all affiliated hose replace, Fuel filter replace and Fuel pump and sender replace. None of this cured the issue.
I am now 90% sure it is a leaky fuel injector. I think what is happening is that the car runs then is turned off and there is a very slow fuel injector leak which is causing the difficult restart. Then when the car sits over night all the gas from the leak evaporates and there is no trouble on the first start of the day.
My question is does any one have a detailed description on how to pull the fuel rail with the injectors still attached to determine which injector(s) is/are leaking? Or is there another way to determine which injuector is leaking without pulling the rail?
