Pretty sure my computer is fried, want to see what you guys think

Symptoms: when turning key relay would click once and then lose power, no dash mm interior lights, no nothing. Currently dash, interior, and external lights not doing anything with key turned

Tried: checked battery(12.5), got power at the under hood fuse box, relays swapped, fuses checked, grounds checked. Everything checks good

Found a pin out of the C1 plug on the PCM, need to check voltage when I'm done with work. Anyone else run into this or similar?

@TheShakes Do you have any codes prior to this issue? How is your shifting from 1st to 2nd in the morning?

I think it's like Candyman, you have to say his name 3 times.

I do have the jerky 1-2 shift when engine isn't warmed up. No codes when I got to work, no way to read codes now

The hard shift from 1st to 2nd is the transmission side of the computer failing you. You can call me at 866-888-7710 to discuss in Further detail if you’d like.

You might want to check your ignition switch. Of course, your exterior lights are independent of the ignition (and PCM).

What is the location number of that loose wire from C1? The color of the wire?

What is the battery voltage while (attempting to) crank?

Have you looked at the FSM yet?
