I have never checked the cranking pressure of a known running truck. With just the 9 psi it still should fire up and idle at 30 psi.Well no luck again, crank but no start. This time I am getting small puffs of white out of the stack.
Quick question,will the fuel pressure after the booster pump raise while cranking or only when running? I noticed my gauge on my secondary filters stays around 9psi while cranking., which is the same as my feed pump puts out.
