EBAY K swap tucked harness NO SPARK fix.

Shout out to @Lotus for helping guide me!
EDIT: Also I wanted to add, we are still using this harness with little problems. I ended up cutting and soldering in a factory connector to the crank sensor CKP and throttle pos sensor TPS. The connectors that come with this harness are junk and allow a break in contact intermittently because they fit loose causing insane stuttering/misfiring for the CKP and a bunch of throttle problems for the TPS. For others, this could affect other sensors, so it's up to you to figure if each connector is snug and monitor all data streams to make sure everything is functioning correctly, all the time. Keep this in mind if you do buy this harness, some do not have junkyards nearby.
If you have one of those eBay / china tucked harnesses and are not getting spark and or your radiator fan turns on after cranking then you need to swap pins 7 and 20 at the C101 connector. I also recommend buying a quality solid ground lug for 16ga wire with a 5/16 hole and replacing the ring terminal on the harness.

Thanks for the feedback on that guys. The harness looks quality-wise a bit questionable. What is the wire size and insulation specification of these? Any idea?
Can you help me out as well I swapped the pins over and the car started right up. Then stalled out. Now it won’t start again? Any tips? Is it the ground wire on that harness? No codes either
Are you still getting spark? fuel? timing is good?
Yes I’m getting spark and fuel. Just checked timing and it is good. Motors freshly rebuilt. Get code for p1361 should I get a new cam sensor or check wiring first? My dvom is at work so I would have to wait till tomrorow.

also so
Bad news I oull
Valve cover to check timing and the oil is milky I guess from sitting for over a year. But I did change it like three months ago but never ran it. Could that cause a start up then die? Will change tomorrow the oil and clean head.

Kinda think it could be the signal wire from the cam rsx sensor, I was looking at the color of the harness to the pin on the ecu and they were different color
Milky oil won't stop the vehicle starting.
going to pin test cam sensors and crank sensors when the weather allows. Will keep updated. As I’m using same harness as the guy on this thread.

So I ended up pin testing and cam sensors are good and so are crank so mayb the sensor it self ?
So it ended up being a bad map sensor I was looking at kpro and it wasn’t reading right.
