To test amp output to coil: Disconnect the low voltage wires from the coil and connect meter to those wires. You should have a resistance of 500 to 800 ohms.
To test amp input from ECU: With the ECU disconnected, you should have a resistance of 1000 to 1500 ohms between ECU pins 24 and 25.
To test amp ground: unplug amp and check minimal resistance between brown wire and earth.

right i tested this and got a reading of about 5500 ohms on pins 24 and 25 so i bought a brand new ignition amp from matt lewis today fitted it and it gave me the same reading what could be cause of this incorrect reading. the ign out put resistance is fine.
basicly the car will start and run and then the revs will pick up very slightly and then the car will cut out turn the ignition on and off a few times and she will fire up again found a link on here with an ecu pin out abd what resistances each sensor should be and everything is ok apart from the ign amp.
please help before i turn to the darkside and break it and go jap!!!!!!
cheers,
Phil
