Here is a link to the factory service manual for a '78 car. (edited out)

There should be several "Test" procedures that should help. There's lot's of fuel injection stuff in the archives, (I know its tough to find somewhere to start)

Read through the section on the fuel injection in the service manual (as per SBlake linky) and I'll try to find the link to the nissan fuel injection book.

Thanks for the info

rzkas, good morning! i have a 77 280z. My problem is I have replaced tank, pump and filter. My car is also a automatic. I can drive and when it gets sort of hot it will sort of cut off, sounds like fuel not a overheating issue. Do you have any suggestions?

hi, sorry for the late response. i dont know but i will look up info and i will get back to you.

DBender,

here is a zip file for the '77fsm.

This should help. http://www.xenons30.com/files/FSM/77_datsun_280z.pdf.gz
