I have an 05 with just under 125k miles. On my way home today the truck just died with no warning. I coated to shoulder and turned off at tried to start truck.....not start. It cranks but won't urn over. After I got towed home I connected my PHP FICM tuner and monitor(my only device to read DTC) and got trouble codes p1378 and p2290. When cranking for a short time the ICP psi stays at 0, ICP volt is .24, irp % 14.5 and the numbers didn't move much. I know the FICM had been replaced before prior to when I bought it, I installed bullet proof diesel full oil cooler and egr cooler package about 15k miles ago, and new altanator about 8k miles ago.
Not sure what exactly it is but would love to know what y'all think or have experienced
