The CPS is not giving off volts on voltage meter. Engine cranks but no start. Security light off. Check engine light on.

Hello, I am Danny.

Is that what the check engine light is showing? Do you have the code number? It is located on the right rear lower part of engine near starter. Picture attached. Hope this helps and feel free to ask any questions if needed. Thanks for using 2CarPros.

Okay, so hi Danny. I recently did an engine overhaul in my truck I might have damaged the wiring harness or the crankshaft sensor dm. So basically what I am trying to say is that I cannot get a reading from the constant on the three pigtail crankshaft sensor. Is there anything the could possibly stop the positive from draw power? Thanks for your response and would like to here from you soon.

Thanks,
Vince
