code 1241 *ITS THE INJECTOR * let me guess, the lift will start and shut down in a few seconds? right?
the resistance of the coil is not correct causing the ecm to read over current and shut down. if you bypass the fuel shut off solenoid circuit it will work till the new injector comes in. i have had several that check good resistance but will code out in a known good truck. swap the injector from another truck and test it (if avail) note i have 1 tb45 series that all i did was swap the harness connectors and problem disapeared.
