code 41 in the CCM and no start
Hi, having problems with my 93 LT1 6sp. I have a no start condition, engine cranks but no injector pulse. 12v to the injector but no pulsed ground.
The CCM shows a C41 (no communication) and I have checked the wires for any opens or shorts and continuity. Everything checks good, no shorts or opens and .5 ohms between the CCM and the ECM. I see in the schematic there is a splice (S222) in the circut. Can anyone tell me where the splice is, I think I may have corrosion causing an interuption in the communication. Thanks in advance for any help.
