Replaced plugs and coil packs, throttle body (includes throttle sensor), accelerator pedal assembly (includes accelerator sensor), and fuel injector wiring harness.

First errors started during driving while raining and accelerating up hill; received a traction control issue.
Not long after that accelerating at all would result in barely moving or a feeling of low power moving.
The low powered moving would occasionally get a burst of acceleration along with dark smoke coming from exhaust. This would dissipate and go back to low powered moving.
Now, nothing works. Please help this is my only vehicle and I can’t afford a new one at this time.
Thanks in advance.

You have a wiring issue. I am attaching the testing that you need to run through in order to try and find the issue. Looks like the wiring harness that is related to the ignition switch is involved so let's run through the testing for the B1370 code.

I attached all the info below for this including the wiring diagrams needed to test the wiring for a short to voltage and an open between the BCM and ignition switch.

Let me know if you have questions but here is a guide that will help as well:

Unfortunately there is no easy way to figure this out other then to do the testing. Let me know what questions you have. Thanks
