just replaced the fuel pump on my 76 280z...it started with no problem before and not working now. I checked to see if pump is working and it sure is working as I unpluged the hose at the filter it was pumping gas. I think it's an elertical problem, but I'm not sure where to start.

Think this through: Why would a fuel pump replacement result in an ELECTRICAL problem afterward? It just doesn't make sense. Especially since you point out the pump IS working properly.

Are you sure you did NOT do anything else? Even as simple as changing fuses, re-connecting wires that seemed to go together or even adjusting timing etc.

If you are sure that you did NOT do anything else, post back and people will take a stab at it.

What kind of pump are we talking about? What year is your Z?

Could be something as simple as knocking a wire off with your elbow.
I have done that:stupid:

Could the system just need to be primed? (I don't actually know if the FI systems need that, just a thought.)

If you pulled the pump there may be air in the fuel lines that needs to be purged.

Is this a new pump or a used one? Do you get an appropriate fuel pressure reading (30-someodd psi, as I recall)?

Current Z: 1978 280Z, mostly stock, with some electrical mods.  Semi-daily driver.
First Z: a brilliant, gold, 1975 280Z for my daily commute.
Also in the fleet: '94 Miata, '92 Saturn SL2, and '09 Dodge Ram (token modern vehicle).
