ka24e running on 3 cylinders
 

hey guys

earlier today as i was changing my oil i noticed that a hose that goes from the fuel pressure regulator to the intake manifold came off, it was loose so I slipped it back on and put a metal clamp on it.

so i was done with the oil change and ready to test drive, now the engine is shaking terribly and now the exhaust sounds like this

<<< not my car.

So I went ahead and pulled the spark plug wires out one by one while idleing to see which cylinder was not firing, and came to the conclusion that it was the 3rd cylinder. There was still spark going to the 3rd cylinder so then I swapped the spark plugs.

No luck, the 3rd cylinder was still not firing.

Then I checked the injectors, I swapped the 3rd injector with a working one i had sitting around. Still only running on cylinders 1, 2 and 4.

Any suggestions? My guess is that the wiring for the 3rd injector is messed up somewhere either the connector itself or the wiring. Car does not blow smoke or make any abnormal sounds so i don't think that the 3rd cylinder just suddenly blew up.

Just wanted to get a few opinions before I have to tear up my engine harness.


COLES NOTES:

- CAR RUNS ON CYLINDERS 1 2 and 4
- problem isnt with the spark plug or the wires or the distro
- problem isnt the fuel injector itself
- possible wiring issue
- would like input on this

OH and its bone stock btw

You have a KA. There's your problem right there :troll:

FALSE ALARM!!!

the injector connector was corroded and when I wiggled the wire around it fixed it.

now i need a injector wiring harness.

fuck im such an idiot

Could've just as easily been a dead plug FYI

^ lol yeah but the thing is i've unplug and plugged the connector throughout all the testing at least 10 times and it didnt do anything until i just grabbed the wires and wiggled them lol.
