Customer Question

i have a code 254 on my n14 cummins in my 99 frieghtliner century series 120. i have followed the troubleshooting tree and found no faults yet. i have checked resistance in the circuit and in the fuel solenoid to chassis both are within specs. i have also checked my ground to chassis and my "+" terminal on my starter. my ecm reads 13.6 volts at idle and never dropped even when the fault is present. ive also pulled the ecm connector with the circuit to the fuel solenoid and checked for continuity to grounds and all other pins in the that connector. what else can i do with out condemning an ECM.. another thing is i have two trucks with the exact same issue.
