e30 M50 code 1264 after fixing no start issue. May have cut a wire

[e30m20TurbO7]

Ended up finding the issue
it was a green and white wire I accidentally cut when removing the harness I believe it went to an ignition related wire. I have a new issue now
this could be an area I may have accidentally cut in the harness causing this. Or it could be something else
current status is the car is misfiring when running I swapped out some coils but didn’t see a change.
inneed to remove coils and plugs and check everything
but I’ll figure that out when I need to.
right now I HAVE A CEL CODE 1264
I WENT AHEAD AND REPLACED THE O2 sensor
still no change THE CODE READS OUT TO BE EGO HEATER CIRCUIT IM THINKING I should figure this out before messing with the misfire.
has anyone had this code with a 24v swap car ??
1264 ego heater
o2 sensor heater relay.
anynadvice where I should start with the multimeter ? Where to check for power first ? Or where I should start searching for a short
Also using a non oem o2
also I swapped out dme’s when diagnosing the no start issue in the past. Soo I’m not sure which one I originally used and if that could be the cause. Going to start tracing all wires back and lebelung them to rule out cut wire or short

I took this engine wiring cover off by cutting it out and I then tucked the wiring harness over the eco and pulled it in to put the relays tucked and the cover mounted in the glove box cleanly, after I did so. I lost Cel light, fuel pump prime, and, I went through some things light if figured out I have power to the relays , but I'm not receiving power to fuel pump but will if I jump the relay, but won't get any Ignition, iv checked my grounds, and powers and I believe I have everything in the proper place, I think when I unwrapped my c101 connector I have pottenilly 2 wires pulled out, or I had two just sitting in there and I forgot I taped them up , soo I put them in the designated wire hole. soo I still don't receive signal for check engine light, if I jump the fuel pump relay I spray gas under the car from to much pressure, the car is fucking with me, soo there's a burn on one of the relay plug I posted picture , I don't believe the relays are firing, I've taken good relays from another car I know works, so I don't think the relays are the problem, I I really need help with a direction, to go, im about to buy another harness and restart, I had this car running before I took a wiring harness cover off of the original harness plastic shield,/ mount, and installed it under the e30 m3 wiring harness ,
soo is it more possible I damaged a wire by pinching it. ive tried to go through everything , im about to remove the harness and go through harness again, properly, and redo the connector by pushing each pin out , and plugging them in manually and then reconnecting it ,
any advice would be awesome as im really struggling with some advice on a direction,
if someone could help ill pay them 3102996047

No power to fuel pump unless I jump relay or squeeze it with the cover off
assuming dme is not grounded

You need a new fuel pump relay. Does the engine start when the relay is jumped?

Connect the violet/green wire to the red/wihite wire of the fuel pump relay. Both fuel pumps should turn on with the key on.

Have 11.87 volts to fuel pump relay with key off. 11.87 volts to center relay with key on
