I have 1997 ford 7.3L with marginal hpop pressure
I replaced the hpop about 3 weeks ago no pressure when tested dead headed pump with guage attached 5 volts to
elect mag. also replaced idr valve pump is doa
now that I'm back on the road with new pump kept getting code p1211 so I tested the pressure again at 5 volt to idr
I'm only getting about 1400 psi dead headed. obviously I'm thinking bad or weak pump
I've searched ever where trying to find a procedure to test ipr valve I found on you tube a guy using pressure with hose to first o ring and then putting power to idr valve to close valve both of my idrs had a slow leak with power applied 5 volts and large flow with no power air pressure was only 40 psi is this normal.
