If you connect (touch) the starter relay large "batt" threaded stud with the nearby brown wire/terminal which goes down to the solenoid on the starter together with a screwdriver & it will crank AND if you have power at the yellow wire "ign" terminal on the starter relay when the key is held to "crank" with a helper with the "grn" starter relay terminal grounded to a nearby ground and the starter at that point in time will not crank then the starter relay is open (bad). In the first sentence, the procedure: Lay the screwdriver on the threaded stud then touch the nearby brown wire terminal so the sparks (contact) is at the brown wire terminal as opposed to the threads on the stud (not a dealbreaker but a bit more better procedure) & a jumper with a pair of alligator clips is even better.
