Re: Columbus..the 1957 IH 4x4..
Long overdue updates...
I'm still fighting the no-crank issues..
I've done everything I know to do..
Checked all grounds...all good..doubled them up anyway
Have constant 12v and key on and crank 12v
Checked fuel pressure..58psi
Checked crank sensor, it bench tests good and backpinned at the ecm plug it shows signal
Checked cam sensor, it also bench tests good and backpinned at the ecm plug it shows signal
Had 37 (haha) people telling me to change them anyway..so I did..still no crank..
Checked wire pin locations in plugs, all good
Had ecm checked twice..no issues there.. put it in 2 diff trucks..both ran fine with my ecm..
Checked injectors multiple times ..all spray good.. checked injector solenoid with stethoscope, can hear them firing.. remove intake , raise up above engine ..crank it over..all 8 injectors are spraying..
Pull engine down to check cam , marks line up perfect.. still will not crank..
Pour gas in throttle..itll crank right up every time and run til poured in gas runs out..
Trying to get up with a different tuner and see if he can figure out what's going on..
Very very frustrating..so far 2 different tuners, psi tech, and 3 different mechanics all say theres no reason it wont run..
So til that happens ,on to other things...
