I just bought a nistune ecu second hand, plugged into my harness and nothing, like if I have no ecu in my car, fuel pump doesn't prime, car turns over but doesn't even hiccup to turn on or anything, doesn't even connect to nistune software when I hookup the Nissan consult cable, ecu is dead? There are no burn marks whatsoever on te computer

S13 sr20det please help

Pop open the ECU and ensure the nistune board is still connected.

Yes it is still connected

Does the SR20 ECU have a led on it like the Z32/RB25 and all of the other nissans?

If thats never on, check the voltage into the ECU, if needed open the ECU up and use a voltmeter across what should be a large diode.

That should give you battery voltage.

You'll need to have the key to "On"
