good evening my name is ***** ***** I will assist
the gray wire should have 12 volts for only 2 seconds when the key is turned on. it will deliver 12 volts constantly when cranking and running.
if it has this, and the car wont start you most likely have a bad fuel pump. if it does not, then we need to talk further.
what is the original issue??
