95 s14 ka24de

okay so i go and start my car and drive it 5 mins and park it, runs fine and then i start it back up again, its sputtering really bad and the car is shaking. I drive it home and i

-check the compression and its all 180psi
-check spark and they are all good
-check fuel injectors and first three are good but the last one is not.

I check this by unplugging each injector harness and when i unplug the first three its gets worse but when i unplug the last on its the same. so i swap the last injector with the third injector and go to unplug them and the third is now the same when i unplug it and the last one gets worse when i unplug it. so i figured it was a bad injector. I purchased a new injector and replace the third injector since the bad one is in there and i swapped the good one to number four already.

Now i drive the car and its blowing white smoke and smells of gas really bad and is back firing with flames coming out. i check the injectors again and the last one is bad again?

so is this a harness issue or ecu issue?

I also have 6 CEL codes:

-p0170 fuel trim bank 1

-p0325 knock sensor1 circuit bank 1

-p0110 intake air temperature sensor 1 circuit ( i have an intake and the sensor is not plugged up)

-p0335 crankshaft position sensor A circuit

-p1136 nissan
1.ckp sensor (pcs) cog
2.crankshaft/camshaft sensor range/performance

-p0705 tranmission range sensor circuit (PRNDL)

what is the cause of this and how do i go about fixing this?

how would i go about checking if the plug for the injector has the right amount of power coming through the wires to the injector?

i have this but have no idea how to use it?
