    You sure all the fuses to do with cranking are ok? Did you swap in a known good fuse, a spare? Or do a eye test

    Installing a transceiver and inadvertently caused an arc directly behind the interior fuse box, blew the 30 amp fuse. Truck cranks, no dash lights no start. Have verified all fuses and tested relays, reset control module. OBDII will not communicate with truck. Will check OBDII connector in the morning ( make sure it is getting contact) but am stumped. Any suggestions?
    Tested all with multi- meter.

    All good now replaced 30 amp fuse, THANKS to the person who posted how to remove the passenger dash, was able to remove the ECU ( without breaking anything) and sent it off to G7 computer for repair, reinstalled and all is good. Thank you everyone for your help!

    What did the repair cost - if you don't mind sharing?

    $225.00 plus shipping to them, they turned it around in 24 hours from receiving the unit, also the cost of the 30 amp fuse which I think was $7.00 ish. It was a software issue on the ECU.
