What would cause this?
This is a screen shot from my 94 c3500 dually. ecm 16196395 BHDF. I have been trying to chase down a miss that happens around 2000 rpm's. I can visually see the injectors shutting off for a split second. I am still learning how to data log but I was able to capture the miss. Here is a screen shot of what it looks like. Does anyone have any idea what would cause it to lose voltage and cut power to the fuel pump? It also looks like the battery voltage also shows near zero.Data log.jpg
