Ignition off.
Reinstall connectors, components etc.
Ignition on.
Disconnect the connector from mass air flow (MAF) sensor.
Check the voltage of the mass air flow (MAF) sensor #1. It should be approximately Ubat.
Ignition off.
Check the system relay when it "releases" (approximately 2 minutes after ignition off).

Check the voltage on mass air flow (MAF) sensor #1. It should be 0 V when the system relay is not drawing on it.

Is the mass air flow (MAF) sensor #1 voltage 0 Volts?
