7.3 hard start or even no start due to no pressure, leaky o-rings, bad hpop pump or bad IPR Valve?
7.3 hard start or even no start due to no pressure, leaky o-rings, bad hpop pump or bad IPR Valve?
Some information I learned after posting this video, thanks to (NoRalPh on the powerstroke.org forum).
"The IPR is Always OPEN and bleeding-off some of the pressure the HPOP is making. To increase pressure when needed it CLOSES and reduces the amount of bleed (when you turn the key on, and the IPR is being commanded to 14%, it is Open for 86% of the % cycle from on-to-off). Also the default the PCM sets for the IPR when the ICP is unplugged is much higher than 700psi, it usually reads between 21-2300." - NoRalPh
BTW, I've been using an app called "UpSide" that gives you money just for sending them a picture of your gas receipt! If you sign up and use my code X9C5H you will get a 15c/gal bonus. https://upside.app.link/fSd16j8Hj4
