I am heaving really long initial cranking problem 10-15 seconds before it fires up most of the time ,at times it will fire up right away but most of the time it takes that long to get it started ,after that will start right up till it sits for a while and then same long crank problem . My starter cranks fast enough ,new Optimo battery under the hood , cam/crank lights on XFI and XIM blinking but no go for 10 plus seconds .Volts shown by XFI about 0.2V less then what voltmeter reads at the batery ,fuel pressure 45 key on while cranking 50 psi ,battery 10.5 volts or more while cranking , I tried adjusting injector offset - batt volts , crank fuel , timing from 20 to 35 deg , seams no different . Ran out of ideas , anybody have this problem ? I will be happy to post tune and log files in anybody willing to look at them .
Thanks
