Hopefully somebody here can help me:
1998 cat 1lw 3406e in freightliner classic
No start
Ecm will not power up
power supply and grounds have been verfied and load tested (keyed hot, constant hot, and ground)
Ecm has been bench tested and ran on boyd caterpillar dyno in corbin ky and is good
Check engine and engine stop lights do not come on on dash but i have confirmed that they do work (bulbs not bad and wires are good)
What am i missing???
