check the solenoid wire at started for power when switch at start position.
If no power, check neutral safety switch, or main ignition switch on steering column under dash.
NOT the key tumbler assembly it has a rod that goes down column to the ignition switch
You should locate and test the solenoid. Most have three connections. There is a large cable from the battery to the solenoid, from the solenoid to the starter and from the start switch to the solenoid. The power terminals to the battery and the starter are large and have large cables. The starter switch connection is much smaller. Turning the key to 'start' provides a low current voltage to the solenoid causing the solenoid relay to close and power from the battery cable to connect through to the starter. If that voltage is present then the solenoid or the wiring between the solenoid and battery or solenoid and starter is suspect. If that voltage is missing then the starter switch or solenoid feed line may have failed.
It could be a weak battery. The starter solenoid may be defective. If so a rebuilt starter could cure the problem.
check the ECT sensor with a scan tool
Sounds like a bad starter solenoid
Bad starter? Bad starter solenoid? Bad neutral switch?
Check the starter solenoid first, followed by the starter. The starter is either not getting power from the solenoid or the starter itself is bad.
Loose or corroded battery cable? Engine seized? Bad starter? Bad starter solenoid? Bad neutral safety switch?
Loose or corroded battery cable? Engine seized? Bad starter? Bad starter solenoid? Bad neutral safety switch?
Check for: weak battery Loose or corroded battery cables Loose wire on starter Bad starter Bad starter solenoid Bad neutral safety switch
dash lights and tail lights cut out
Could be the fusible link from the starter solenoid to the starter itself. Also, other fusible links are installed by the manufacturer of the vehicle to protect your entire electrical system. A wiring diagram will be a great help in finding where all you fusible links are installed.
Weak battery? Loose or corroded battery cables? Starter solenoid?
