pull the yellow wire/female connector off of the starter relay to disable the starter. have a helper hold the ign key to "start". you under the hood & see if the brown wire/downstream end connection on the ballast resistor has fire then check the other end of that brown wire back at the bulkhead for fire & if not hot then either the proper wire in the dangling pull apart ign sw connector under the st column or the plug in connector on the ign switch itself depending on what yr you are working with & this "ign2" "crank" circuit needs to be hot. 2 terminal (single} ballast resistor and 4 terminal ECU (or parts house 5 pinner with a dummy 5th pin) system I am assuming.
