    94 150 standard trouble shooting

    Oh yea its a 4.9 i6 manual 'standard'
    Hi it's -40f this fine night driving home when it died.
    Codes I got was
    11,16,11,45,65,11,61,14,56,51,21,13,34,21,13,34
    I think these are what they mean
    11
    16 - rpm to low to check oxygen sensor test or fuel control error
    11 system pass?
    45 - Coil 1 primary circuit failure
    65 - Charging system over voltage
    11
    61 - Engine coolant temperature circuit grounded
    14 - engine rpm signal fault or PIP circuit failure
    56 - Mass air flow circuit above maximum voltage
    51 - Engine coolant temperature sensor circuit open
    21- Engine coolant temperature (ECT) out of self-test range
    13 - DC motor did not move
    34 - EGR valve circuit out of self-test range
    21 - Engine coolant temperature (ECT) out of self-test range
    13 - DC motor did not move
    34 - EGR valve circuit out of self-test range
    11
    Anyone know where to start my guess is look around for grounded wires following from the driver side loom up down to passenger side
    Or is there a better place to start?

    More context about when led to this is I had the truck warm up for an hour before leaving during some quick acceleration I did have some sputtering but no light
    I do have an antifreeze leak I think from improper mixture but did get it corrected at this time.

    No issues on the highway untill I slowed down to my turn off the highway I then noticed the gages looked like the truck was off blower motor to loud to hear the truck died but knew instantly that my turn was going to be un assisted I had enough speed to just coast it around the turn and get to the side of the Rd. Then towed home to test.
    no garage.

    Here is my intro :
