Long cranking truck, hot or cold
I just finished doing studs & gaskets, injectors, fuel system, mad turbo, stand pipes, dummy plugs, icp sensor, and a new oil filter stand tube on a 2006 f250. Truck already has an updated stc. Truck fired after two 15 second cranks. I let it idle while I buttoned some things up (reassemble interior, change coolant filter, etc). Truck ran really strong. Then I shut it down to do some exhaust work and it still took 8-10 seconds to fire back up. After idling for 20 minutes could I still have air in the system? Could the new filter stand tube be letting the oil drain back (oem filter and cap)? What Icp and Ipr PIDS should I be monitoring with my CTS?
