No RPM indication on 6.0 with Holley Terminator Max X
I am at a loss, and appreciate any insight you all can give. I have not been able to figure this one out with the forums.
I am installing a 6.0 from a 2003 Yukon into my 1981 Jeep J10.
I am using the Holley Terminator Max X wiring harness with a 24x reluctor, drive by wire throttle, and an automatic transmission.
We tried to start the engine for the first time today, and can not get spark, fuel, or RPM indication on the handheld controller.
LEDs 6 and 7 indicate as expected. 6 (Crankshaft position sensor) is solid green. LED 7 (camshaft position sensor) flashes between green and blue during cranking). Handheld RPM continues to indicate "STALL".
In everything I have found online, a lack of RPM indication is likely due to camshaft or crankshaft sensor issues and will shut off injectors and coil packs. I have replaced both the camshaft and crankshaft sensors and validated all ground indications and harness wiring. I have also validated voltage at both sensors.
Anyone have any ideas? Thanks in advance.
