fuel inj not working

Check for one constant power on the fuel injector harness -if you got it-could be the ground driver in the computer or an input signal from a sensor problem to the computer causing the computer not to snchronize the injectors-

Just to add to this one how do you know the fuel injection is not working?Also is the security light on solid or flashing with the key on?If so your injectors will be disabled due to anti theft mode.

tested all inj with test light on the ground side

So you have no power feed to the injectors?Also is the security light on solid or flashing while trying to start it?Any codes in the computer?Have you checked all the fuses especially the injector fuse?
