12v but no power to anything
So I have a 92 sc300 that I had to remove the engine to do some work to it. I left the harness connected to the connectors like you should and pulled the harness with the engine. I had everything connected and the ecu hooked up and there was full power to everything inside the car. The fuel pump turned on just fine and the dash lights came on just fine. I went to go crank it over and the starter just clicked, it didnt turn the engine over. After that 1 attempt to actually start the engine I have literally no power to anything. All of the main fuses are good in under hood fuse box. I tried to swap relays and still nothing. I have 12v at the ignition switch. Ive been going through wiring diagrams and should there be 12v at the ecu for pin 33 (black with red stripe)? Anyone have any thoughts on how to narrow this down? Every fuse I checked was good unless im missing some. I checked the ones on the left kick panel in the little fuse box and they all had continuity. BTW I am running an AEM V1. It was tuned by larry at sound performance. Everything worked before I went to pull the engine and trans and re install it.
