Question about 2003 Toyota Corolla

1 Answer

Starting problem Jumper cables didn't help. Hitting the starter with a tire iron did. When the ignition switch was turned you can hear a motor, but the engine doesn't attempt to turn over.

It sounds like your problem is in the starter motor solenoid. That is what is responsible for engaging the starter motor to crank over the engine. Nowadays the solenoid and the starter motor are a unit. You could attempt to repair the solenoid but most technicians would go ahead and replace your starter (the solenoid and the motor).
However, having said that it is important that you check your connections to be good and clean and your battery to be charged.

Tip

Trouble-shooting your Isuzu starter..


Basic operation of a starter:
Your engine's starter motor is an electrical motor that is used to rotate the engine in order to get it to fire up. This motor draws a large amont of current from the battery (in the order of 70 Amps and up). In order to supply power to the starter a solenoid is used, it acts as a switch between the battery and the starter motor. This solenoid also engages the starter gear with the engine's flywheel and disengages it once the engine is started. Because the circuit for the solenoid also draws a heavy current a further relay is needed to control it.
The diagram below shows the electrical layout of the starting system.
  • i : Battery
  • ii : Starter relay(located in the relay box in the engine compartment)
  • iii : Starter solenoid
  • iv : Starter incorporating solenoid and motor.
  • v : Engine
  • vi : Battery earth cable
  • vii : Engine earth cable
  • viii : Ignition fuse
  • ix : Starter fuse
  • x : Solenoid to starter supply cable
  • xi : Ignition switch
  • xii : Starter motor
When the ignition(xi) is turned it supplies power from the battery through fuse (viii) to the starter relay(ii).
The starter relay activates and supplies power to the starter solenoid(iii) via fuse (ix)
The starter solenoid activates and connects power from the battery to the starter via a short cable(x) between the solenoid and starter motor. This allows the starter motor to turn.

General trouble shooting.
Turn the ignition off.
1/ First you need to check that the fuses are intact.
Keep the ignition off. Place the vehicle in Neutral. Chock the wheels and engage the parking brake.
2/ To prove the starter motor, connect power from the battery positive to the cable (x). This must be done with jumper cables. Touch the jumper cable to the connector on the back of the solenoid where cable (x) connects. Take care not to short circuit the jumper cable to the engine or vehicle body. It can be a tight fit and might not always be possible. If you hear the starter motor spin then it is working along with the engine earth cable. If not, connect the negative lead of the jumper cable between the battery and the starter motor body or any other bare piece of metal on the engine and put the positive lead on cable (x) again. If the starter motor does not spin it needs to come out for repair/replacement. If it spins check both the battery earth cable and engine earth cable and repair where nescasary.
3/ Once the starter motor has been proved move on to the solenoid. Remove the thin wire from the solenoid. Using a small piece of wire, connect battery positive to the connector where you just took off the wire. The solenoid should kick in and the starter motor will turn the engine. If the solenoid does not kick in, remove the starter for repair/replacement of the solenoid. If the solenoid kicks in then replace the starter relay.

If the starting circuit still does not operate the fault will be in the wiring. This needs reasonable expertise and if you dont have a voltmeter handy is not advised.
Bear in mind on automatic transmission vehicles there is an additional switch (Mode switch) wired in between the ignition switch and the starter relay. This switch is on the transmission itself and if faulty will not allow the starter to operate even if steps 1 to 3 were successfull. The same goes for the anti theft/immobiliser system.

  • xii : Starter motor
  • xiii : 80A Main fusible link FL-1(Relay fuse box)
  • xiv : 50 A Key SW fusible link FL-2(relay fuse box)
  • xv : Mode switch(A/T only - mounted on the side of the transmission) and for 6 cylinder manual transmission engines this is the clutch start switch mounted on the clutch pedal.

Why am I having problems starting my Bravada. There is power, the started worksb, but when I turn the key nothing happens.All the dash board lights come on but no starter engagement?


do the dashboard lights go out when key turned to start? when you say nothing happens,is there a click? does the motor turn over,but not fire? is it an automatic,meaning is the gear inhibitor switch preventing starter from working?have you tried a jumper battery?putting a jumper lead from the battery earth to the engine ground helps sometimes,if earthing cables broken

Pontiac g6 won't start not the battery could it be the starter makes no noise when key is turned?


The ignition switch sends voltage to the starter solenoid, if no neutral or brake switch is involved. It is sometimes located ON the starter. It activates a high-current switch that engages the starter. If you don't hear a click, the solenoid could be bad. Since the high current can damage the contacts, you could still hear a click and not get the starter to spin. Sometimes hitting the solenoid, or starter lightly with a wrench or hammer will realign the contacts and you can get another spin from the starter. Hitting the exposed contact on the cable that goes straight from the battery to the solenoid can cause a spark, or explode the battery.

So, the ignition switch, battery, starter, starter solenoid, a fuse, a neutral switch, brake switch, or wiring can be the cause of a starter not engaging.

MY VAN WILL NOT CRANK IT WAS OUT OF GAS SO I PUT TWENTY DOLLARS IN THE TANK AND IT STILL WILL NOT TURN OVER


do all the dash lights turn on etc?
If so you could try and see if its a bad earth connection by connecting a jumper cable from the battery neutral to a good earth point on the engine and try to crank again.
Obviously many things it could be:
Faulty ignition switch Immobiliser Starter Motor Jammed Motor, Cables or Contacts Corroded Stuck or Failed Starter Solenoid Flat Battery
Try the Jumper Lead and Battery as first easy tests

I hear a click clack sound under hood on right side by solenoid switch when turn ignition


It can be several things. First, try unhooking and cleaning the Battery terminals and the Battery cables. Then reattach them and try starting your car.

If that does not work you need to test the Solenoid. Unhook the small wires on top of the Solenoid. Then take a Battery jumper cable and attach one end to the Battery cable nut on the Battery side of the Solenoid. Take the other end and touch the Terminal nut on the Starter side of the Solenoid. The Starter should spin. It will arc a little, but the engine should be cranking using the jumper cable to supply power. Remove the jumper and reattach the small wires.

Now you can diagnose the problem. Primarily you need a good Battery, if you could bypass the Solenoid and get the engine to spin at normal speed-the Solenoid is bad. If the Jumper cable really arcs and the Starter refuses to turn, the Starter is bad. If the engine slowly cranks with the jumper cable, the Battery is weak or bad or the Starter is dragging.

The click-clack noise you hear are the contacts inside the Solenoid. The Solenoid is the weakest connection between the Battery and the Starter. If either the Battery or the Starter is bad the Solenoid will make the sound. It does not mean the Solenoid is bad. The test I wrote about will verify if the Solenoid is bad when you bypass the Solenoid. You go on to testing the Battery and Starter with the methods I presented. It is really more simple to do than to write about.

Hi
Easiest test is to reconnect jumper cables and switch lights on, if these work and no noise AT ALL from starter, NO clicking at all then could be the jumper cables are too light like most are. Try 2 sets of jumper cables. Ensure that the cables are correclty applied, Red to Red and the black is the last connection to a good steel part on your engine, NOT the battery.Always ensure the car being used to jump from is running at all times while cables are connected.When it starts remove this one FIRST also.

97 cavalier wont start when turning key nothing happens


if the starter motor doesn't turn at all, and all you hear is a clicking then the starter is bad and the solenoid is good

if the starter is turning and the car still doesn't start then the starter motor is slipping and is bad

to check the solenoid put a jumper from the main battery lead (Large Red) to the ignition wire switch (Smaller Purple) is the starter operates the solenoid and starter are ok and you problem is in the ignition switch, or nuetral switch, or wiring.

Car won't crank


Hi,

Initially, it might be the starting solenoid or ignition switch.

A backgrounder on the starter system. The starter system is initiated at the ignition switch when the key is turned to start. At this point, the ignition switch then provides +12VDC to a starter relay (if the vehicle has got one) but more often straight to the starting solenoid. The relay is but a remote switch with slightly higher amperage capacity. The starter relay then engages and supplies +12VDC to the staring solenoid. The starting solenoid then performs two (2) functions. It provides the switching action (hundreds amps) from the battery heavy cable to the actual starter motor. The solenoid likewise pushes a small pinion gear along the shaft of the starter motor to engage the ring gear. The ring gear is of course on the edge of the flywheel which in turn is attached to the crankshaft.

Starter system problems could be corrected by:
1. check battery, battery cables and connections;
2. charge the battery if required;
3. clean brushes and guides of brush holders of the starter motor;
4. clean the commutator and commutator segments;
5. check/replace the armature or field coils if determined to be defective;
6. in some extreme cases it could be the drive pinion or the flywheel gear ring is defective.
7. often it is the big switch that the solenoid activates that looses contacts causing no +12V internally to the motor.
8. Most likely would be a defective starter relay or the IGN switch itself. Relative to this, you might try and check the connectors/terminals and electrical joints.

In the picture below, the upper portion is the starter solenoid while the one below it is the actual starter.

Given the amount of work to overhaul a starter, you might consider just replacing it.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
