I am hoping to get some help with this before I put a match in the tank of this car!!! I have a friend who owns this car, i am trying to help her out.... The background is 3 different people have played with it, so i am find random things along the way, like someone put the fuel pump relay in the wrong spot.... The original issue was a water pump and timing belt, when they changed them they couldn't get the car to run. I diagnosed the issue down to the crank position sensor, someone broke it while changing the belt. Below are the steps i have gone through so far:
1) Replaced crank position sensor due to it being broke
2) Replaced all the plugs as they were covered in oil
3) Replaced valve cover gasket due to oil leaking in plugs
3) Replaced coil packs due to ECU putting 5v to the trigger all the time and melting them, i can only assumes one of the prior repair people did something to short the ECU (maybe breaking the CPS)
4) Replaced ECU with one from junkyard due to the transistor on the coil pack being melted and putting 5v to the coils all the time, the new ECU has the wrong VIN, but my bidirectional Launch X431 doesn't have an option to change the VIN on this car., i am not sure if this effects anything on this old a model. I called the dealership and they basically said unless i bought a new ECU from them there was nothing they could do.
5) Checked compression in each cylinder 180-190 PSI in each one
6) Switching coil packs doesn't change the issue, unplugged each plug wire/ coil pack and each made the car run worse and drew a notable spark
7) Unplugging injectors doesn't change the issue, checked fuel pressure at the tank and at the engine, 48 PSI, while running and revving the engine pressure stays consistent
8) Short term fuel trim stays around 24% when it is idling and goes to -5% when you raise the RPM to 3,500 ish the long term is around 12% O2 sensor bank 1 reads around 78 mv and bank 2 reads 0 to 19.5mv
8) Cleaned MAF with the proper cleaner, sprayed carb cleaner it all around the intake and nothing made the car surge or raise the o2 readings (no air leak after the MAF I could find)
9) Spray starting fluid in the air filter and the o2 goes up to .9v and car runs smoother
10) I have an oscilloscope, but i am far from proficient at using it, i was able to see the cam and crank sensors are producing square waves (0-5v), but that's about all I can see.
11) I pulled the new plugs and they are black already.

Sorry I know this is a lot of information but I am trying to step through the things that would lead to a random misfire. My understanding is the car thinks it is running lean, so it dumps in fuel, the black plugs tell a different story. The video shows what all the pertinent sensors are doing while the car is running (and you can hear the misfire). Any help or direction to look/check would be greatly appreciated... I am at a loss. I'm not sure what else to look at, the car is almost un drivable due to the misfire, to the point where it will stall out.
