Question about 2000 Lexus RX 300

1 Answer

When I turn the ignition to start my vehicle I hear the starter spinning but the engine does not. when I release the ignition I still hear the starter for a second or two, almost sounds like the starter is not coupling with the pinion gear. It usually takes me two to three tries but eventually the car will start.

1999 Pontiac Sunfire 5 speed won't start. Replaced spark plugs and checked ignition coil (fine). Sounds like it wants to turn over but makes a "whining" noise. Please assist. Thank you!


Is the engine turning over with the key in the start position? If the engine is not spinning over and you hear a whining noise, the starter is not engaging the flywheel. If the engine is turning over with the starter engaged, the engine has most likely jumped time that creates low or no compression which results in the whining noise.

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.

The following is specifically for Isuzu Trooper and Rodeo :
  • i : Battery
  • ii : Starter relay(located in the relay fuse box in the engine compartment designated X-17)
  • iii : Starter solenoid
  • iv : Starter incorporating solenoid and motor.
  • v : Engine
  • vi : Battery earth cable
  • vii : Engine earth cable
  • viii : 10A Starter fuse C-1(Fuse box: LH footwell on LHD vehicle, RH dash on RHD vehicle)
  • x : Solenoid to starter supply cable
  • xi : Ignition switch
  • 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.
  • xvi : Anti theft system
  • B2 : B2 on ignition sitch
  • ST : ST on ignition switch

How to wire a relay

2002 hyundai Santa fe will not start. I turn key and starter turned for 3 seconds then stopped and now when i turn key NOTHING. I hear a circuit sound in back of car when i turn key but no other sound. ...


Definitely a starting system problem. That sound you hear in the back is the fuel pump.

Starting system circuit components (besides wiring harness)
1. Ignition Key Switch - closes the starter relay control circuit to energize the relay and close the contacts inside the relay (you can check this by locating the relay in the underhood fuse/relay box and have a friend turn the key while you listen/feel if the relay 'clicks'
2. Starter Relay or its Contacts
3. Starter Solenoid - pushes/pulls the starter gear into the engine's flywheel ring-gear and its contacts close to provide battery power to the starter itself.
4. Starter itself - poor brush contact with the armature's commutator will prevent the starter to spin/turn

If you are 'Electrically' talented, you can check to see if you're getting battery power to the starter solenoid by using a simple 12 volt test light/bulb. Connect one lead to the starter solenoid terminal and the other to chassis/engine ground and have a buddy turn the ignition key - if the light turns 'ON', then you know that particular circuit is OK but the starter solenoid is not energizing to push the starter gear into the flywheel ring-gear to turn the engine over. If it doesn't, the problem is elsewhere (wiring, starter relay, starter relay control circuit, etc).

You can have a qualified Hyundai Service Technician properly diagnose your vehicle. OR, you can Go to www.hmaservice.com and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, illustrations, etc.

1995 gmc serria will not start no click from starter, manual trans


replace the starter. Being a manual transmission you should be able to pop the clutch to get it going till you replace the starter. If you don't know how to pop the clutch follow these steps. That way you can still drive the car. When need to.
  1. Get inside the vehicle and depress the clutch to shift the car into "Neutral." Insert the key into the ignition and turn it to the "On" position. This is the place the key would be after a normal turn of the ignition switch for starting. Instead, with a clutch pop, the ignition will already need to be on so that when the engine is turned over, the key is in the On position.

  2. Move the car in position to be pushed from behind or sent down a slope for the starting procedure. Check to see that the brakes will work when pressed and how hard the steering wheel will need to be turned before the vehicle is started. Power steering and brakes will make both systems work poorly until the vehicle is started.
  3. 3 Sitting inside the driver's seat with the clutch depressed, put the shifter into first gear. Keep your foot depressed onto the clutch and the brake pedal without depressing the brake pedal. Roll down the window and signal to your helper to push. As the car rolls, you will steer toward any slope that will assist the helper in getting the car down the street. Allow the momentum of the vehicle to increase to constant motion.
  4. 4 Release the clutch quickly and be prepared to throttle the gas pedal as the engine is turned over by the motion of the vehicle. When in gear, the engine will be forced to crank and the ignition will send a spark for a start. The quicker the vehicle is going before the clutch is released will determine how many times the engine will turn over. More cranks equal more opportunities to ignite the gas and air for combustion and the engine to start without a battery or starter

The starter has been tested as good, but the car wont start, any ideas?


load test battery
check for tight, clean connections at battery
check neutral safety or clutch safety switch
check starter relay
check ignition switch
check engine and chassis grounds,

Four types of starter motor are utilized depending upon the vehicle transaxle and assembly plant location. Manual transaxle equipped vehicles utilize a conventional starter motor which consists of a yoke, an armature assembly, an overrunning clutch assembly, a solenoid, a commutator end cover, a brush holder and a pinion drive lever. Automatic transaxle equipped vehicles utilize a reduction type starter motor which has, in addition to the components found on conventional starter motors, a reduction gear and shock absorber assembly.
In the basic circuit, the solenoid windings are energized when the ignition switch is turn to the START position and the clutch start/neutral safety switch is closed. The resulting plunger and shift lever movement causes the pinion to engage the engine flywheel ring gear. This movement also causes the starter solenoid contacts to close.
With the contacts closed, the starter solenoid provides a closed circuit between the battery positive terminal and the starter motor. Because the starter motor is permanently grounded to the engine block, the circuit is complete and cranking occurs as soon as the starter solenoid contacts are closed.
When the engine starts, the pinion is designed to overrun and protect the armature from excessive speed until the ignition switch is released from the START position. With the ignition switch released, a return spring in the solenoid assembly forces the starter solenoid contacts open, breaks the circuit between the battery and the starter motor, and disengages the pinion. To prevent prolonged overrun, the ignition switch should be immediately released upon engine start-up.
See Figures 1 and 2

When I insert key to start the car it will not turn at all. What is this part called?


The component is a starter. When you insert your key into the ignition and turn it, you switch on the power to the coil and vehicle computers. By turning the key to the start position it will supply power to the starter and solenoid which cranks the engine until you release the key allowing to return to the ignition on position. If the battery is weak the starter solenoid may engage producing a clicking sound, but it will not crank the engine. Another test is to turn on the dome light and try to start the vehicle, if you see the dome light dim when you are trying to start the car the battery is weak or the starter has a short. Starters are temperamental at times and can be intermittent working sometimes and malfunction other times. Your ignition switch, fuse, or relay could also produce symptoms of your vehicle not cranking.

01 s10 security disconnected now no start


I suppose if you are determined on not fixing the problem correctly and you can start the vehicle by jumping the starter relay, you could rig a relay of your own from the column off of the starter signal wire from the ignition wire from the ignition switch to the starter. I personally think you should fix the problem with the security system installed on the vehicle. If price is an issue, buy the part from a junk yard, but remember the security has to be learned as followed.

30 Minute Learn Procedure
  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to start the engine, then release the key to ON, vehicle will not start.
  3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
  4. Turn OFF the ignition, and wait 5 seconds.
  5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes, the vehicle is now ready to relearn the Passlock™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
  6. Important: The vehicle learns the Passlock™ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
  7. Start the engine, the vehicle has now learned the Passlock™ Sensor Data Code and/or password.
  8. With a scan tool, clear any DTCs if needed, history DTCs will self clear after 100 ignition cycles.

Vehicle Won't Start


The solution to this problem was simple, embarrasing and frustrating. The dome light was left on, and discharged the battery....enough to prevent the ignition from firing apparently. I did not suspect this, because the starter would turn the engine over very well, for a long time, and would do this repeatedly. In all my experience, I have never seen an engine spin that well and not start. According to the dealer, the voltage was too low for the ignition to work. While I do not know the exact threshhold where the voltage is too low to crank, I could have detected the condition by checking the voltage at the battery while cranking. It should have been significantly below 12 volts, indicating a low battery. The tow truck driver who picked it up simply used a portable battery to jump it off and cranked it with no problem. The symptom of the starter continuing to run after releasing the key is new technology with computerized controls, and is normal nowdays. You don't really notice this because the engine usually fires so quickly that it is undetectable.

When starting car turning ignition only hear a spinning sound but car didnt start


Probably the starter itself, or the starter solenoid on the side of the starter. Usually only available as one unit anyway for most vehicles. Make sure the starter motor connections are all tight before replacing it, wiring and retaining bolts, hopefully that's all it is. The other possibility is that the flywheel ring-gear could be damaged and not allowing the starter pinion gear to engage, in which case that would need to be replaced also, which involves removing the gearbox, so hope thats not the problem!

Hope this helps,
Mark.
