Cannot get power to the small wire going to the starter
You need to know how it works before you can diagnose it. There is a starter relay in the under hood fuse/relay box .. This relay is controlled by the PCM - engine computer . Does you car have a anti-theft system ? a red light on top of the dash or a SECURITY light on instrument cluster ? Is the red light flashing fast when trying to start the car . If you find an pull the relay out an look on the bottom you will or should see four numbers . 30 & 87 , 85 & 86. You can test from the socket where the relay plugs in . PIN'S 87 & 85 should have B+ voltage . PIN 30 takes voltage from PIN 87 to start the vehicle , PIN 86 is the control from the engine computer . The PCM gives a ground on this circuit to energize the relay closing the contacts inside ,completing the circuit between B+ voltage on PIN 87 to PIN 30 to start the car.
