97 chevy Silverado 5.7 z71

Asked by Mar 05, 2016 at 02:01 PM about the Chevrolet Silverado 1500

Question type: Maintenance & Repair

Have a 97 Chevy z71. It's not turning over and
says it's the crank sensor. Has a new crank sensor
in it. I've got a 7 volt reference and everything I've
read says it's supposed to have a 5 volt. How do I
run this down? Can anyone provide an accurate
diagram?

Do you have 7 volts on all of the reference voltage points or just the crank sensor? If just the crank sensor I would look for some wire chafing with a possible resistive short to power. If they all read 7 volts it is very likely that the ECM is on its way out, but make sure that all of the connections are clean and you have good ECM grounds. Good grounds are a must on this rig. I have even ran a few additionals direct from the battery on some of the problem rigs I have dealt with through the years.
