Hi I am trying to create an e38 standalone harness. I have the e38 ecu from 2007 ve ss commodore.I am not getting any fuel injector or spark signals. I have had the body control module and vats removed from the ecu. The fuel pump primes when I turn the car on. I can crank the engine. Checking with an oscilloscope I am getting crank and cam sensor signal at the ecu. With an obd2 reader I can see cranking rpm. Does anyone know why this is happening help would be much appreciated.
