No crank no start, good battery, some of the electrical stuff works and some of it doesn't. I don't have any wiring diagrams to help me find the ignition or starter relays.

Hi,

Both the starter fuse and relay are located in the fuse box under the hood. See pic 1 below for locations.

Next, I attached the wiring schematic for the starter circuit. Note that the 40-amp starter fuse doesn't get power until the key is in the start position and the relay actuates.

I had to cut the schematic in half to make it readable for you. I did overlap the two so that you can follow from one to the next.

Let me know if this helps or if you have questions.

Take care,

Joe
