No crank no start?

Hi,

I feel like I've seen this vehicle before. Were we working on it prior?

As far as the starter not working, do this. On the starter motor, there will be a heavy gauge red wire that will have battery voltage at all times, so don't short it but confirm it has power. There will also be a purple wire that is smaller in diameter. It will not have power until the key is in the start position. So, have a helper turn the key to start while you check if the purple wire gets power. If it does, the starter is bad. If not, then we need to see where power is being lost.

Next, when checking a fuse for power, you need to only use the ground/negative side of the battery. The power should come from the pins where the fuse goes.

Next, the relay is a 4-pin relay. I attached the schematic below and highlighted the relay. Note there are four wires associated with it.

If you take a test light, ground one side to the battery negative. Probe one pin at a time. One should have battery voltage and turn the light on. Next, have a helper turn the key to the start position. At this point, an additional one of the pins in the box should have power and light the test light.

Now, at this point, out of the 4 pins in the relay box, you found power to two of them. That leaves two left. One will go to the purple wire on the starter and will not have power or ground. The other will have ground at all times. So, you need to check the remaining two pins to see if one has continuity to ground.

Let me know if that helps and what you find. Additionally, let me know if you have other questions.

Take care,
