Try this........
1.....Disconnect battery ground
2.....In the engine bay disconnect the yellow start wire from the "push on" terminal of the starter relay
(There are two wires......one goes to the neutral safety switch on the transmission, the other goes into the main engine harness. That last one is what you want)
3....Take an ohmeter and with the key "locked" check resistance from the yellow wire to ground. It should be OPEN
