On my way back to work from lunch my trans started slipping so I hooked up the ids and checked codes. After I pulled codes, my truck would just crank and not start. Icp was about 600psi, has rpm and sync, ficm is a 58v for swamps with a php tune but voltage was 47 and 9. Did an injector buzz test and got codes for all 8 injectors, So I pulled the ficm and checked for corrosion in the pins and found none. Put the ficm back on and ran a buzz test again, it passed and the truck started. I shut it off and restarted it a couple times and then parked it. When I went to leave work it did the same thing. I'm thinking the ficm is at fault even with the good voltage. Anybody have ficm issues like this before?
