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.
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.
check the ECT sensor with a scan tool
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
That's the most likely reason, yes a bad solenoid. I like to go in order to diagnose a problem so to get to that decision I'd start by : Kick the engine over or hit the starter button and turn the engine over. If it does not turn over, either the starter or starter gears are bad, transmission is stuck, or the engine is stuck. If the starter solenoid clicks, but the starter does not turn, check the charge of the battery. If the battery is fully charged, use some heavy jumper cables and connect the positive jumper cable directly to the starter cable. That's the big, thick, cable going from the starter solenoid to the starter. When you make the connection, there will be a big spark and the starter should turn. If it does, the solenoid is bad. If nothing happens, the starter cable is broken or the starter is bad. Try connecting directly to the starter motor, if possible. If the starter turns, but the engine does not, the starter gears or starter clutch is bad. If the starter does not turn, either the starter is bad or the engine is stuck.
Yes, a bad starter or starter solenoid can be the reason for a car not starting but all the lights coming on. It could be a battery going bad or being drained.
dash lights and tail lights cut out
Weak battery? Loose or corroded battery cables? Starter solenoid?
Try starting the car. If it doesn't start, then you might have a low charge in your battery! Turn the headlights on and then try to start the car - if the lights dim and you can hear the starter motor solenoid "click" or the starter turns the engine slowly then your battery is more than likely at fault. -if the lights don't dim and you can't hear anything from the starter motor then it is likely to be a loose earth connection or a loose connection to the starter motor solenoid (the thin cable out of the two that connect to your starter motor) Simples.
Loose battery cable? Bad starter? ( checkwires on starter) Bad starter solenoid? Bad Neutral or clutch safety switch?
Battery cable connections may not be tight. The starter could be bad. The starter solenoid could be bad. Check to see if the lights work. If they do, leave them on and try to start the vehicle. IF the lights dim, you have a bad battery connection somewhere or a bad starter.
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.
Assuming the starter does not crank over the engine. Bad starter, starter solenoid or relay. Bad battery. Loose/dirty connections between battery and starter. Bad or out of adjustment neutral safety switch.
seized engine? bad starter solenoid? bad starter? loose or corroded battery cable? bad neutral switch?
Dead short between ignition switch and starter solenoid trigger wire?
Seized engine? Perhaps neutral safety switch? Starter solenoid? Bad starter? Iginition switch?
Check the starter solenoid and starter on the Regal. One of these is probably breaking down in the cold weather.
Seized engine? Weak battery? Loose or corroded battery cables? Bad starter? Bad starter solenoid? Bad neutral or clutch safety switch?
Do lights come on when turning ignition on? If so, then you have a bad starter/solenoid/relay. If not then, you may have a bad battery or connection or ground.
When key is on, is there power?(lights on the dash) If so, check starter/relay/solenoid. If not, check battery terminals, cables and fuses.
Starter solenoid is not making contact to turn starter motor. Replace starter or solenoid(which is on the starter) !st try the battery posts. look and see if tight and clean... same thing happened to me i tightened it ,and the caddy started right up
