wondering if there are any techs here know if a ECM from a donor truck can be used to replace or test my possible bad one.
My 05 5.9 has a no start no gauge movement, only dash lights and crank over.
proir to this the vehicle was attemted to be jump started at a dealer impound lot.
any ideas? I checked all fuses, fusible links, relays, ignition switch.
no change...
here is the other question can a dealer test the ECM off the truck?
thanks for any help.
any tech in San diego here?
