I have a late model 260Z w/Weber downdraft DGV's. After the car sits for about 2 days I have to use starter fluid to get it started (or kill the battery cranking).

I assume the gas is draining back to the tank from the carbs. Is the problem in the carbs, or the fuel pump?

More info required...

Do you pump the pedal when cranking? This should achieve the same as squirting in a prime... unless it's broke (probably won't drive well if this is the case).

Is the choke working? Is it mechanical or auto? If mechanical, are you pulling it on? (Sorry, I've worked on a Computer Help Desk - you've got to ask these things :).

Is it a mechanical or electric fuel pump? If mechanical, does your engine slowly fade and die when idling? If electric, does it help if you leave the ignition on for a while before cranking?

Does you car restart easily after 0-1 days?

How cold is it wherever you are? (It's Summer here in Canberra :).

Does it fire at all without priming?

I guess we have to wait for two days before you answer... :)

Yep... I'd say the gas is draining back. I have a 260 with webers and an electric fuel pump. If it sits for a few days i have to turn the ignition on and listen til the ticking of the pump quiets down and then start it. ( about 15-30 seconds)With choke on of course.

I don't hear that tell-tale clicking when i turn the ignition, so i guess the problem is my fuel pump or the wiring. At least I know where to start.

Thanks alot.
