Hello,

I'm trying to start an Aristo 2jz on the engine stand but i dont seem to be getting spark. The etcs-i is working, but there is no voltage between B+ and ground on the plug for the d61 igniter.

I have the pins in red connected to positive and the one in blue to ground. also have walbro 485 hooked up for fuel in a bucket.

No maf at the moment, but it should still fire at least

Do you have your ecu grounded? Mine wouldn't start unless the ecu was grounded.

do i just ground the case?

Your sensors are not grounded . The EC that you grounded is just the AC pressure switches ground. All the grounds on B1 and B2 connector should be grounded. They are for the sensor / ecu ground needed by the ECU to read parameters it needs to fire the engine.

Those arent tied to the block on the harness? there are no loose ends that i can remember but ill double check

it should be ...but just trying to make sure since it wasn't mentioned what wiring you used or how the engine was wired . I was thinking you rigged your own since you said the ETCS-i is working ... I don't see the +BM pin wired which provides power to the eletronic throttle system which sends signals to the ECU.
