Ignition issue

I would check that everything is grounded good.
when I was wrenching, I had my "ground harness tester"
it was a jumper cable clamp, and about 10 16ga wires with a bunch of various sized big gator clips
jumper clamp to battery -
then I'd reground everything and if it started, then one at a time remove the small grounds till it quit
70% of all my wire repairs were grounds issues
