Hello guys
I have read past posts on the hard morning start issue and have done most of the fixes and need help identifying a few more. My truck will have it's little difficulty after sitting for 8 hours or more. If it is started before than there is no issue, it starts right up. During the hard start it will not fire at all with out putting your foot to the floor. It stumbles several times before starting and won't even stumble for at least 1 min of cranking, not continuous of course. Maybe I should let you know what I have done.
Replace fuel return lines
90 elbow
fuel water separator
pre-filter screen o-rings
checked overflow spring 1/2"
checked fuel solenoid function cleaned
solenoid contacts appear fine no corrosion
What next?
This is becoming very frustrating, trying to start with winter temps dipping below zero and cranking this long the batteries are getting hammered.
Any help appreciated, are there links to helpful threads?
