Hi z-community,
I have some trouble with my 280z engine - it is starting very hard - needs a lot attempts and then runs very weak - after getting warm the engine run is getting better, but takes gas very bad - nearly stopping when cold - and misfiring often ...
With the following link you could experience the behavior:

... the engine run half a hour before, so was not too cold. without this it would need 8-10 start attempts until coming to live ...
What did I try hitherto:
1. as the fuel pump that was mounted (also not original) whas very loud - I ordered an aftermarket pump from zcardepot.com (https://zcardepot.com/electric-fuel-pump-fuel-injection-280z-280zx.html) and mounted this ... it also is getting very loud when the engine is running
2. i checked the spark plugs - exchanged them to the originally recommended NGKs - and adjusted the distance to 1,1mm als recommended in the service manual
3. checked ignation cables and connectors - all looks normal
4. checked ignation distributor - is new and looks normal - adjusted the ignition moment towards preignation - so the engine runs a bit smoother
5. removed the from the previous owner in Phoenix mounted open sports air filter and mounted the repainted original filter box with a new K&N filter
Would should I do next to optimize the engine run?
Does anybody have the some experience and a solution form me?
I am very thankful for every hint and help!
thank you, Chris from Austria
