Where do you find the crank voltage on a relay?
Where do you find the crank voltage on a relay?
The “crank” voltage you found at the fuse goes to the neutral safety switch next, then to the relay. Check for voltage at the relay socket terminals. You should find 12 volts on one of them all the time. The other terminal on the same side will have 12 volts in the “crank” position.
What should I do if my engine won’t Crank over?
Okay, go to the fuse called crank on the lower left side of the dash and check for power to the fuse with the key in the start position. helpful? I’ve checked all of the related fuses and relays. On the starter relay I have power to pin 30 but when I crank it I get no power to pin 85. The relay is good. helpful? Please stop.
What does no start no crank no click mean?
If you have a late model GM vehicle and turn the key only to hear nothing, you’ll most likely think you have a dead battery—and you may. But a no start, no crank, no click condition can be far more involved than that. In the old days, power flowed through the ignition switch and down to the starter solenoid. Not anymore.
Why is my test light not cranking over?
If it does not, suspect the neutral safety switch, or more commonly, a broken wire near it or the gear shift is out of adjustment. To double-check the other two terminals in the socket, move the ground clip of your test light to the battery positive terminal, then probe the two remaining terminals in the relay socket.
Why is my Chevy Silverado 1500 not starting?
However, today, when the truck will crank and start, the antitheft icon goes off after a few seconds with the key on and stays off while the truck is running. It never flashed either today or yesterday though. And I don’t know if the antitheft system disables cranking or starting or both.

What is a typical GM starting system wiring diagram?
Click on the image here to pull up a PDF of a typical GM starting system wiring diagram. Depending on the year, model and engine of your GM vehicle, your starting system may be less complicated or use only some of the components shown here. For example, earlier anti-theft systems didn’t communicate the same way with the PCM.
