I never got a chance to plug off the return line a second time, so I didn't get that. I had only monitored the voltage. I bought a used assembly from a low miliage wrecked express. I figured a GM one used was way petty than any aftermarket unit. Thing was, from day to day the van ran fine. Its used in the service feild every work day & for the most part, it always ran fine, just would excessivly crank about once every 6-8 starts.
One of those nagging things that I just put off.
Glad its cured, it seems to run better than it has in the past 30K miles.
Thanks for all your help!
