So my Z6 will only fire 3 cyl. wont fire the one on drivers side. ive replaced everything i could think of.... all but ecu and harness. compression is perfect and just put a new head on too... checked the voltage for the injector plug and its 11volts on and off. anyone have any idea what might be causing this problem? like i said ive tried everything i can think of and its not worked. any help would be great.

 

anyone?

 

did u check your distributer cap?

 

ya ive tried 3 different dizzy's. a new head, plugs, plug wires, Injectors, fuel rail, intake mani.

 

anyone have an idea? i tested the injector plug for the 4th cyl and it got 11 volts.

 

ok try swapping the bad injecter on to a different spot and see if the misfire changes over. if you have checked everything else then try a new injecter.

 

did you remove your ecu at all, I was having a problem with one of my injectors and it ended up being a pin was not getting a good connection at the ecu.

 

ive tried the switch. i have brand new ones in it now. ill try the ecu thing. so you just unplugg it and replugg it?
