Airflow meter was my first guess also, back when I first started playing with this thing. If I remember correctly, if I unpluged the electrical connector on the sensor, the engine would not even start. If I left the electric connector attached but took the whole assembly off of the rubber intake hose, it would start but still only run for the 3 seconds. I did check voltages going to the connector - and I concluded that was not the problem, and started looking somewhere else.
MAP sensor - that is one that I have not checked yet. Do you know the procedure?
I have concluded that the Fuel pressure regulator is bad - 50 psi at the rail, with the pump running, vacuum attached or not - pressure drops to 5psi as soon as the fuel pump stops. Will also replace the fuel rail - the center part where the small o ring seats is not round and it lookd that might be the reason for the pressure drop.
Also found that one of the coils is arking to the valve cover - under the boot - as it sits on top of the plug.
Was thinking that maybe the arking coil is tripping the missfire sensor and shutting the whole thing off?
