I just put new injectors in my Z, and im having problems. One injector went out, so i replaced it. A month later another went out, so I decided to replace them all. After replacing them the car cranked over, then locked up. After about two hours of sitting I tryed it again, and the same thing happened. I think one or more of the injectors is stuck open.

Any ideas???

welcome to nico

when you saiy it "locked up" does it simply stop turning with the key? tried a jump? will tt turn by hand? it is possible that a bad injector O ring will severly flood the engine but not likely to be bad enough to lock the motor, the injectors pretty much nevre fail open, if you are dumping fuel the more likely issue is an injector O ring, thats the problem with side feed injectors if that lower O ring goes out the fuel rail just empties into the cylinder

Thats what it was. I pulled the sparkplugs, and the plugs to the fuel injectors. I cranked to over and it was shooting out gas like an garden hose!! I fixed to o ring, and changed the oil. Now it runs great!!

Thank!!
