81 280zx Turbo fuel problem
the engine will start but if I shut it off and try
to start it again it runs to rich and won't start
unless I leave it for about a hour then it will
start again. I've replaced the fuel regulator
and still have the same problem ,
suggestions ?
I'm guessing its a air metering problem, see if you can swap the air flow meter w/ known good one.
Check the temp sensor as well
I had that issue and it was the Cylinder Head Temperature Sensor, The connector was super corroded. I changed the CHTS and cleaned the connector. When the CHTS goes bad it dumps fuel into the engine until the sparkplugs are too wet to fire. If you jumper the CHTS connector by putting a wire into each end you trick the engine into thinking its good and warmed up, and it stops dumping extra fuel into the engine.
Clean or change out this CHTS connector.
