I am wondering more about an injector. Even the FICM can sometimes act up cold and not warm.
Ed at FICM repair.com has even mentioned heating up the FICM w/ a heat gun or hair dryer and then trying the "cold" start.
Regardless, it is more and more evident that owners need a scantool to troubleshoot their vehicles.
A scangaugeII can be had for $135. The DashBoss is pretty nice too I hear - if you have the electronics for it.
Did I say That ???? Didnt mean it that way if I did
I didnt mean the HPO Pump would Bleed Down them 05+ HPOP are the GOOD Ones I dont think thats the Problem IMO Sorrey if I confussed Him
I ment the Standpipes or Dummey plugs may cause it to bleed down
GREAT Call on the Injectors to that top O-Ring could also cause it to Bleed Off
