Early EDM non-cat 4A-GE 16v Bluetop Fails emissions (high co)

[Rascal21]

Probably only thing I can check is volume and thats if I dont mess up the O-rings (no spares).

Ah, checked out a parts head with injectors still in it, they`re grey also.
Re-checked resistance on the injectors on the engine currently, theyre 2.3 ohm (within factory spec).
So not the injectors

Also checked and cleaned the parts injectors, theyre 2.1 Ohm resistance (and have been sitting for a while), so they would probably be ganked anyway.
Either way I`ll try them out.

But if Earth on one end of the warning lamp wont work, I might as well try Positive.
I.e Earth on W-pin on ECU, and Positive on 12v+
Would be kinda funny if this is why I cant get the warning lamp fired and people saying bad ECU
