Why is there no power at the crank fuse?
If you have no power at the crank fuse then the ignition switch must have failed. Unless the ignition switch red wire does not have power. Here is the wire diagram of the circuit.
What is the power at crank fuse on a Chevy Silverado?
Red/white – power all the time. Small red power all the time. Small yellow – power at crank. Small white – power on with key for accessories. Traced yellow wire to relay on fuse box. Trips relay. Has power. Still no power at crank fuse. By the diagram, the yellow wire goes from the ignition switch to the I/P fuse box where the crank fuse is.
Where is the fuse block on a GMC Sierra?
The center instrument panel utility block is located underneath the instrument panel, to the left of the steering column. The underhood fuse block in the engine compartment on the driver’s side of the vehicle near the battery. Lift the cover for access to the fuse/relay block.
Is there power at crank on Chevy Silverado?
The back of the relay also includes the brown, orange, pink and white cables from the switch. That’s the one. There is power on the yellow at crank. I can also feel and hear the relay click when I apply power. The RAP relay may be powering off, during crank, that is why it may be clicking.
If you have no power at the crank fuse then the ignition switch must have failed. Unless the ignition switch red wire does not have power. Here is the wire diagram of the circuit.
What to do if your fuse panel is not working?
If those fuses are okay, check the smaller spade-type fuses in the inside fuse box the same way, and try to determine which fuses are dead and which ones do have twelve volts. Do that with the ignition switch in the “run” position. Based on your findings, I will look at the diagram for your engine and see what the dead fuses have in common.

Why is my battery not getting any power?
Tried to start no click no nothing. Batteries good starter is good per checking them. Started checking fuses and sees we are not getting power inside or out fuse boxes. That is where we are at. Thanks for your help. helpful? It sounds like your problem could be an ignition switch or a fusable link.
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.

How many fuses do you need to start a GM car?
But then you must have two good fuses in the starting circuit, two good relays, several good fuses to the BCM, good fuses to the PCM, and good grounds all around. Click on the image here to pull up a PDF of a typical GM starting system wiring diagram.
How do you start a no crank car?
Once the relay coil is grounded, the contacts provide power to the starter solenoid and that provides power to the starter motor. See how simple that was? Start by checking fuses. If they’re good, pull the starter motor relay and use a digital multimeter to check the supply and ground side of the relay coil (key in START position).
Why is the crank fuse not working on my Chevy Silverado?
(It shows no relay) The wire goes directly to the crank fuse. If it is not getting to the fuse then there must be an open in the fuse box or terminals are loose at the fuse. Have you checked for this? Ya. That’s where my confusion is too.
