So my boss aquired a 83 brat.

Won't start and run, it will rev up as soon as you touch the key but die immediately.

I've confirmed fuel pressure, spark, timing and firing order

I'm kinda leaning towards the MAF.
Is there a way to test it and would the NA MAF be close to the turbo MAF?

That sounds like lack of a tach signal to the ECU.

I would hot wire the fuel pump and try again.



No such thing as a NA MAF,


Test yours by moving the flap and monitoring the voltage variation

It's fuel injection,

Tach works, altho I do not know if the signal reaches the ecu.

Fuel pump does run.

And my n/a vs turbo MAF question comes from the ea82 flapper mafs where it took me forever to find a proper non turbo MAF and yes, there was a difference
