Hey guys, I'm having a strange issue with one of my injectors in my 2010 JCW. When I would try to start the car injector 2 just starts dumping fuel into the cylinder. All the others look to be fine.

I pulled the injectors out and they visually look fine, and they have similar ohm readings across the board.

Does anyone have any ideas of other ways to test the injectors?

Does anyone have any ideas what may cause one injector to flood out like that?

thanks!

 

it could be just stuck open.

 

You've tested the injectors. At least replace the injector that dumps fuel. Why? The injector is bad. If the cost is not prohibitive I'd replace all injectors just on general principles.

 

I have not tested them other than with the ohm meter. And sadly cost is prohibitive, especially if that's not the issue. Which I'm thinking is the case.

I swapped out injector 2 and 3. Cyl 2 still fills with fuel.

I even unplugged inj 2 and the cylinder still fills with fuel after I shut the car off. I took intake off too for the heck of it, same thing.

It's very repetitive, I start the car without spark plug 2 in, runs crappy for few seconds, then shut off. I run to engine and look down spark plug hole. I can see fuel flowing very rapidly into cylinder and after a couple seconds it shuts off abruptly.

 

Did you do compression test?

 

nope not yet, I cannot find my compression tester at the moment.

 

If the #2 cylinder fills with fuel after swapping injectors #2 and #3 (and #3 cylinder not manifesting the fuel filling behavior) there must be another source of fuel to account for the fuel in the #2 cylinder. Perhaps an enriching injector?
