77 280 refresh and rebuild - 403443

Featured Replies

I have started to work on my neglected 280Z. Haven't done my own auto repair work in a long time. I am very limited on space and tools at this point.

It has been sitting for nearly 30 years. It was mostly running when parked but had emissions and cooling issues and wasn't in a position to deal with it.

Good news is it is desert climate and the car is intact. I want to get it running and driving, then update and repair more as I go.

I have a goal to get it running for the 50th birthday but I am feeling a little overwhelmed a month into this effort.

Starting with the fuel system back to front. Tank has been cleaned, started replacing some fuel lines.

Trying to not replace anything that I don't have to right now but I am questioning if piecemeal is the best approach for the EFI.

Still considering some fuel system upgrades in the future so I don't want to duplicate my efforts.

Looking to make it a nice driver eventually. I would like to keep it mostly original with some functional or horsepower updates.

Looking for any advice and encouragement I can find. :)

Have you opened up the fuel lines around and on the engine? If you're lucky no moisture made its way up to the injectors. If it was mine I'd let the fuel pump run, with a few gallons in the tank, for an hour or so to purge the old fuel from the rail and injectors. If you don't see rust in the ends of the fuel rail.

Download the 1980 EFI book and do the electrical tests.

Thanks, Zed that’s very helpful.

Most of the tests came out ok but I have some work to do on some of it.
