Hey there, about a week ago I was driving about 65 mph when truck turned off on me and had to get her towed. I already had the IPR changed to fix a no start issue I had a week before. I've got no CEL, new batteries, new CPS from ford, and new fuel filter. Frankly I'm stuck on what to do. If anyone has any ideas or even fault trees, that'd be amazing. Thank you.
Hey there, so I checked the fuse and she looked good. Should I still try to disconnect and see if she starts up? Also you wouldn't happen to know any 7.3 fault trees I can keep on my phone just in case.
So, I did use the torque app to look at some basic stuff (Max was while cranking) Low volt was on old batteries. Heard from a friend if its under 9 when cranking it wouldn't start so I tried changing them out. Anything else I should look up?
Yup, your friend is right, the pcm needs a few values to be met before it will let the injectors fire.
1) min 100rpm cranking speed
2) 500psi of ICP pressure
3) 10v of battery

Check the #22 fuse with a meter, they can look fine and still not be good. This fuse powers the PCM relay among other things and without it nothing works. Also check the #9 fuse under the hood, this one powers the PCM.
With no WTS light this usually means that the PCM isn't getting any power.
