Hello, I’m pretty new to these forums and they have helped me a ton with my project 08’ MCS I picked up, just when I thought I was done with the car it wouldn’t start and I traced it back to the JBE which has water damage and needs to be replaced, as well as all the wires the plug into it. So I got a matching part number JBE managed to find the clips that plug into it as well, soldered the new clips in wire by wire put the new JBE in, and now whenever I start the car it runs super rough, I took the coil packs off spark plugs out, and cylinder 3 fills with gas after cranking it over. I could use any help I can get. A wiring diagram for the JBE would be super beneficial if anyone knows where to get one.
I have a video of me cranking the car over with the plugs and coils out, it shows cylinder 3 filling with gas after the engine is done cranking. I’m not sure how to post videos or pictures on here if you have any questions about anything please inbox me

 

Sounds like a typical stuck injector.

 

Does the JBE have anything to do with when the fuel injectors are supposed to spray ?

 

have no experience with piggy back devices, I have a standalone ecu. But I doubt it would adjust the pulse width to the point where it would hang open. Sounds like a broken injector and if thats the case thats a bummer.. you need a $275 tool kit that reaches around the back of the manifold to get the injectors out.
