Injection Pressure Regulator.. it should have a duty cycle reading in %
With the engine off, the batt. Volttage, should be around 12.6-13.2. Not saying they are bad, but if you can, charge them for at least a couple hours, and then test. Drive, and then let set over nite, and test batt., again. See what the Voltage is then. If it drops, then the batt., are not HOLDING charge....
no STC's work just like everything else in the system, they gradually fail.. usually starts off by an extended crank while hot, then as the o-ring erodes more and more, the longer the crank until it finally blows out and it never starts again.. Like I said though, I have seen some 07's already have the updated one piece fitting, so im unsure on if they all did.. There is no breakdown for that upgrade, you just have to pull the cover and chance it...
I think one rail is leaking down, but just a bit though... the dummy plugs i know for sure are about due for a change, rarely the standpipes blow out, but its one of those while your there....
And deny the INGO Ford bashers their fun? Kill joy.for future ref, just PM me....
