    Default Crank no start

    So Friday I had a fishbite and stall episode. Pulled over truck started fine and ran great rest of the day. Saturday truck starts fine, run some errands and proceed to replace water pump and radiator. I had disconnected the positive cables. Got that all done and now the truck won't start.

    New PMD and cable
    Gutted fss
    Have fuel to ffm,out of air bleed,out of drain and to injection pump
    Fuel in clear retun line, moves a little when cranking
    Tried cranking with optical sensor unplugged and cps unplugged, no difference
    Have SES light when cranking. (power to ecm)
    No fuel out injector lines.
    Tried both pmd without extension harness

    My 98 has a bunch of electrical issues that went away after changing the switch.
    Same on my 2004 Topkick.

    Ignition switch is little box on lower steering column not the key cylinder.

    Not on my 98 or 04 they were mounted on the column behind the key tumbler.

    Every GM I have owned had the switch on the top of the column about 6 inches or so down toward the firewall from the key unit.

    There is a rod that connects the sliding switch to the key/lock unit.

    Later ones that use the "chip key" may be different.

    Our 2007 Avalanche has the chip key
    Spendy to get extras made.

    We only got one key with the rig....so had to get an extra.
    The 07 does not have a locking column either....I was surprised at that.

    Thanks for reporting back! It's always nice to know how things turned out.
    How old/miles was the PCM?
