Jonathan,

I think you need a bit more information on your situation before you can expect anyone to respond to your question. Also, we have a search function that is quite good at retreaving archived information!

Crimp the fuel line and try again, could be dirty needle n seat

Ive dropped the spacer on the float shaft, bugged if i could find it..

I stripped a small length of pvc cable and placed it on the shaft ran for years.

the 280z's are fuel injected, not carbed.

I'm going to guess the water temp sensor is corroded like hell and making it run rich, but it could be something else.

Usually you can start by checking the connections for clean conductors, then check the sensors themselves, then it must be something else.

I'm curious. You had a problem with the injectors not getting power. Apparently you've 'fixed' that if the car now 'runs to rich and floods out'. You never posted that you'd found the solution. What was your fix for the other problem? I only ask because it may have something to do with the present one. Oh, and ignore smokingwheels. Most people do.

hey nissan280z. I think 240zx is right about needing a little more info, but everyone is right about things to check. Corroded coolant temp sensor, mass air meter, fuel pressure regulator. these are all shots in the dark of course but in my experiance they have been good places to start.

I had a similar problem with my '78 280z 2+2. I put in new injectors and it runs like a top.

If replacing the injectors makes things 'less rich, then it sounds like the injectors were stuck open (because of some crud on the needle?) and you chose a $400 cure instead of an $80 cleaning job.

Nillyjarrell-

280Zs didn't have a mass air meter. It's called an Air Flow Meter (AFM.) Wasn't the Mass Air Meter invented around 1995?
