Just bought a mini whinnie. Test drive was fine. Giving it a go through I found a cracked pos battery term, when replacing it the starter solenoid cracked, so I replaced that. Changed wires , plugs , cap rotor. Went to start and nothing. It cranks over but now no start. I changed both relays ( pcr, fuel pump) also new fuel pump and ignition switch. I found no power to the br/ or wire at the pcr relay and now now power to the bk/ lg wire at the fuse box 20a I can't find any info on if the power to the fuse is from a relay , ign or elsewhere. Trying to trace the wire back with no luck

Any info is greatly appreciated

Thanks in advance

It looks like there is an inertia switch, Under right side of dash, on heater plenum. I would hit the reset on that to make sure it has not been tripped, also here is the fuel pump wiring diagrams so you can see how the system works. Did you check the fuel pump relay I would swap that out as well. Here is a guide to help you check for power and see where the power stops:
