ABS C1265 Pump Motor Relay Circuit Open
 

Hi, I have a 1996 Blazer, 4wd, 4 door, 4.3l engine with the abs light on.
the code I have from a scanner is c1265. My question where do you measure the voltage for the pump (big red wire?) and what should the voltage be?

Same Code
 

I scanned and got this same code today. I have been doing some internet research and references to some people who had this problem, replaced the pump ($1000 on Rock Auto) and still had the problem, so it must be wiring. I want to check all of the wiring before I drop the big cash on a pump. Does anyone have something that will help?
