Do you have the pressure solenoi hooked up? If all of the electrical is correct, then I would start looking through the mechanical side of things.

start diagnosing with voltmeter to see if it comes on from ECU end when driving. If not do check diagnostics, i.e. coolant temp, oil pressure, TPS @ WOT, speed sensor input, etc. IF ecu is fine, check for oil pressure at solenoid. before that jsut give solenoid +12v to hear it click.
