Chaps,
My trusty 280zx has failed me..for the first time ever !.
Everything appears normal ( as in all the dash lights come on in response to the rotation of the ignition key ).
Fuel pump primes.
inner wing Efi Relay clicks on.
The starter turns engine as normal.
Battery is good.
I can hear injectors clicking
It just cranks, but wont start.
Plugs have a spark.
Plugs appear to be damp with smell of fuel ( ie not dripping with petrol ! )
Air flow meter flap moves ( ie its not stuck ).
Ive tried with both the cold start injector connected and disconnected.
So I've started to work through the efi bible - and im a bit stuck.
I now want to check the coolant temp sender, I have 2 possible's on the thermostat
housing ( one with a brownish connector and one with a yellowish connector, please see attachment )
But cant tell which is for CTS and which is ( i suspect ) a thermo timer for cold start injector.
And bible suggests checking between pins and body of switch...
Can anyone tell me which is which and whether i should be checking between pins or between pin and switch body....
Cheers muchly
Ash.
