This would be a hi pressure pump for EFI right?

As Mike alluded to, it would help knowing if this 280Z engine in a 240Z is still EFI, or if it has been converted to carbs (more common when a 240Z is concerned). Big difference on what can go wrong there. EFI would always be an electric pump, using relays and the ECU to control it, whereas carbs would be mechanical OR electric, and electric wasn't original in any case it depends on how it got converted.

These contradict each other. You must mean it's a 240z but has a '78 motor and fuel injection. I was running so we know it does work. Because of the electronics it doesn't take much to stop it working.

 

When you turn the key on do you hear the electric fuel pump working???

call your dad and hope not to get Pregnant by your husband.

 

Is this a 280 Z motor converted back to run on Carbs?

As I dont think you would swap all the 280z eleltronic over on to a 72. Most people run the 240Z head on the 280z blocks

:) yeah im gonna bite it an call him. Surprisingly all wiring including dash an everything works perfect in my 240. Its fuel injected. I put alot of time an money in that motor an i wanted a tiny bit better gas milage out of 240. When its running it purrr's. No babies! Ive got dogs an my pit fits perfect in it. :) thanks for advice.
