Good morning, I want to know if you have any solution, my problem arose when I was checking the IAC module of my Jeep Cherokee. It was working normally and out of nowhere it turned off, I tried to turn it back on, and it didn't turn on, I checked everything, it has spark, The pump works, everything works except for the injectors. Which no longer have a pulse. I have a 2-door Jeep Cherokee XJ Sport and the ECU is a Renix automatic 4.0l and 6 cylinders. I already checked the ECU and there is nothing burned inside, it looks like new. What I do?

 

What year, other than Renix?
I'm confused by you mentioning IAC "module" that turned off.

 

I'm guessing that is a translation. If you allowed the IAC to operate while it was removed from the throttle body, it has most likely wound (unwound) past its limits, which is typically restrained by the depth of the IAC bore in the throttle body. If that is the case, as far as I know it is done for (damaged and not repairable) and you will need a new one.

 

Is everything good now?
