Okay I just looked up in my Manual #16, it says the same. 423 should have over 3000 ohms to ground, and when i trigger 424, 423 should drop the ohms to under 1000. My module does it the opposite way. except when I remove the ground wire of the EFI harness. then it will do it the right way. |

The distributor, I don't know what is what, so how can i identify? it is the distributor with the pick up coil and the ignition control module inside it. 2 connectors, the 4-pin is all for the ECU, Ref LOW, REF HI, BYPASS and IC. the 2-pin is + and "C" to the ignition coil.

Are you getting 5V on pin J2-24 Bypass? Is there 5V reference at the MAP pin C and at TPS pin C? https://cimg0.ibsrv.net/gimg/www.off...baf829f5e1.jpg |
I would not continue to troubleshoot anything until a battery and alternator is put into service and there are still issues. . My 02.

When you say you have 5V on the others, is it exactly 5V or close to? |
