[Bassgoat]

2020 Pioneer 1000-5 starts running for a second then shuts down spark and fire only code it blinks Is 13 which is rear injector I've replaced injector the injector harness the fuel pump the plugs checked the coils and wires checked all the relays and fuses checked oil levels checked battery still nothing. It will start back up after the key is shut off and turned back on

Check continuity from the injector wires to pcm. Make sure one isn't broke anywhere inside the wire coating

I need to ask which injector wires/connectors did you buy.
Some of the eBay/amazon specials are reverse polarity.

My research says it shouldn't make a difference. But in our early days making injector kits, we did make a dozen or so reverse.
Most failed to fix the issue. Correct replacements did work.

They do initially spray fuel when key when the key is turned on but after running a sec it's like it goes into protection mode and everything shuts down

Switched wires to make sure it wasn't a reverse polarity issue didn't fix anything we're losing ground pulse to injectors shuts down fuel and fire

Check all the grounds. Hopefully your ecm isn't bad

I also bought a diagnostic to obd2 adapter and itv won't connect to the ecu so im thinking possibly bad ecu

There are a few reports in the forum of the injector driver in the PGM-FI(ecm/ecu) going bad. New or used replacement fixed the issue.
