Hello,

This could be a couple of different things. Let's start with checking the fuses and fusible links. Could you please check IGN SW Maxi Fuse (50A) in the Engine Wiring Harness Junction Block 2, Fuse #7(5A) in the fuse block, and the fusible link going from the alternator to the starter. In the diagrams down below I have included a Starting Circuit Wiring Diagram, and the locations, diagrams, and callouts for both of the fuse boxes where we want you to check a fuse. Please go through these guides and get back to us with what you are able to find out. We can go from there.

Thanks,
Alex
