300zx wont start after injector connector sparked

[sagehenry]

Hi im new to this forum and new to forums in general but i have a technical issue. I removed the injector connector yesterday to tighten up a fuel clamp but forgot to pull the coil pack, so there was power still going to the injector connector and when i set it aside it touched the metal of the intake manifold and sparked several times. i immediately pulled it off the manifold and i reconnected to the top of the injector. Then i went to start it and it would crank but wouldnt start. Could it be a relay? or a fuse of some sort? thank you
