Starter relay signal went out on IPDM...after we stopped for food...truck would not start.
--Ran everything down with the voltmeter...power to the o2 sensors off the harness...only found a weak spot at the IPDM.
Replaced with the NEW IPDM...no change. Have a u1000 code on the OBD2
--Only thing i can figure is that the PNP sensor, TCM or valve control switch is broke. The transmission is definitely in safe mode...runs great or normal in reverse but seems stuck in 5th gear. AND, the relay isnt getting the signal from the trans for starter operation.
Any help or ideas? Part # for the TCM, etc.??
thanks fellas -IZ
