Re: 97 7.3L keep quitting
Just unplug the fuel heater for now (mine's been unplugged for years). Measure the fuel pressure while cranking and running if you can. You should have a minimum of 25 psi
while cranking and at least 40 while running. Sometimes you even need to get a gauge up to the windshield and see what the pressure does under WOT
. Check the fuel regulator screen between the regulator body and bowl. You might even pull the regulator spooland spring out to make sure the spring is not broken or bent and that the bore and spool are not scored. I would swap the CPS
(OEM only) again (if that's not it you'll have a spare for the glovebox. Make sure the oil level is good. Cheers!
