[urq] No stater motor functioning... need help!

thanks for the reply everyone! My dad did a bit more poking around... the
issue seems to be with a splice that the PO had done when installing a 2nd
backup start button. My dad did some poking around last night and found
that he didn't get power at on emoment, and then when he wiggled the wires
around he suddenly had power again! So w/ the starter out of the car, he
can get it to turn over. He's going to clean out the splice and redo it.
Hopefully that will solve the issue!
it seems that some new wires have already been run to this area, but I'm not
100% sure as I haven't started really poking around. I have plans to
install a jumper block in the engine bay much like I did on my turbo'd
4000. Makes life so much easier to have a central post like that. This car
is destined for a 20vt swap, so we will be redoing a LOT of wiring down the
road. That work involves swapping out the under dash fuse box for the one
in the engine bay like the newer Urs and the 4000s.
thanks again for the help everyone! appreciate it!
