He hasn't answered this yet.

If it were wired backwards he may be able to hear it gurgling in to the tank right?

Just an FYI 10 years is a long time for those injectors.  I would also verify you can hear each one clicking. I had a 300ZX I just went through that was sitting for 2 years. None of the I jectors would fire. I had to clean them one by one and lube and apply voltage on and off until they freed.

If i recall right, there was a warning in the user manual of the 280zx that if you run it dry the tank has to be filled for more than 3/4 !  otherwise the pump will not get the fuel to the injectors.. my two cents..

The standard pump has a check valve. What type of pump are you using? Original or aftermarket?

The new eyelets show that it's possible that you have it wired backward.  If you look very closely I think that you'll find a + and a - molded in to the ceramic (or plastic.  Whatever the white material is) where the wire terminal studs are.  The green wire goes to +.

I'll try flipping them

I meant to take your advice sooner and double check but got busy with life

It's just two wires, and a DC motor.  Can't really screw that up beyond accidentally shorting the power wire and blowing a fuse, or connecting the wires backward.  Those are, really, about the only two things that can go wrong.

Sorry.  Keep it simple.  You might have accidentally bumped some other wires or discovered an already existing problem.
