    where should i start

  • Anonymous Jul 21, 2013

    Other than a repair shop You have to have vehicle experience to work on yourself & the ability to use a volt meter Shortly into that process you will need wiring diagrams

Jumped starter terminals 30/87, starter works but no crank when key turned on.


Click no start is typically a bad battery, bad starter, bad solenoid or loose dirty battery connections. But seems you have covered those items. Have you checked you negative battery cable where it attaches to the frame and motor? Use multi meter and check from positive of battery to the motor(block) for 12 volts. Also do this while turning key to start position. If voltage drops out when doing this double check battery voltage and all connections. If it does not drop then check the solenoid wire coming from ignition. When key in start position you should have a good twelve volts. If you you do then test the main leads hooked to solenoid for power. If solenoid wire from ignition has less than 12 volts double check connections at battery and also test the clutch pedal switch.

Starter motor just "clicks" when I turn the key...battery is new and connections are tight.


INSPECT BATTERY CABLES/TERMINALS
BATTERY VOLTAGE ??
WITH KEY IN 'CRANK' POSITION,TEST VOLTAGE TO STARTER SOLENOID 'EXCITEMENT' TERMINAL (SPEC BATTERY VOLTAGE SHOULD BE PRESENT)

I think that you have a defective starter solenoid, this the part that is mounted to the top of the starter.

When I turn the key nothing happens. The starter doesn't even try to draw power from the battery. However, if I by-pass the starter relay it will turn over the motor but will not provide spark or...


Hi! It sounds like a bad solenoid, or that you're not getting the 12 volts to the solenoid to engage the heavy amperage needed to turn thr starter motor.
When you say you bypass it,do you mean you are just crossing the large post of the solenoid with the battery cable connection at the starter?
When you turn the key,you should get 12 volts at least at the smaller post on the solenoid.If you have 12 volts there when the key is all the way to `start 'position,then the starter probably ought to be replaced.
This car being a 2000 is 13 yrs.old.Won't hurt to put a new starter on it.

Turn the key, heard starter solenoid pop, clicking like there wasnt enough power from battery. Replaced battery, turned key, and all the lights on dash went out, unhooked battery checked connection, then...


Either the cable from the battery to the starter is shorted or the starter motor itself has a dead short or the starter relay has a short. As soon as the key is turned, the starter relay is closing and all the power of the battery is heading for the short to ground. That's why the power seems to be lost.

The battery has 12.9 volts, but when I turn the key everything goes dead. In a few minutes I hear two clicks under the dash. The power comes back, but goes out again as soon as I turn the key. ????


Sounds like a loose /dirty connection to to your batterys posts. Remove the connection clean the posts and connectors then re assemble. If it is still doing it charge the battery and also check the starte motor connections. good luck

My 1996 Jeep Grand Cherokee Laredo just stopped starting. All lights, fan, sensors work but engine does nothing when I turn it to start position. What is wrong? Please help.


Assuming that when you turn your key the motor doesn't even try to start.
To start the combustion motor, an electrical motor is used to give it inertia, there are 2 possibilities: one, this electrical motor is not getting the electrical power required, or two, the electrical starter motor is broken. For the first option, check cables all the way from your battery, trough the switch you open or close with your keys, trough a capacitor, to the motor. This motor is generally below or next to the combustion motor, their shafts are mechanically connected by gears. Only the positive pole goes all this way, the negative terminal of the electrical motor is connected to your car's chassis, and so does the battery's negative terminal. If all these connections are OK, then your electrical motor is gone, in which case you'd better buy a new one and replace it, because fixing it would not be an easy task. You can try also replacing the capacitor, which must be on the way between the electrical motor and the key switch, if this is broken, your car should be very weakly trying to start as if the battery was low.

Turn ignition key and motor starts up, next day turn ignition key and motor just turns over and wont start. could it be anti theft problem its a 2002 f150 4 wheel drive with 4.6 liter


This could be caused by either a faulty Crank Shaft Position Sensor or the anti-theft system. Try put key in, turn to ON position for EXACTLY 10 minutes, As SOON as anti-theft light shuts off or stops flashing, then IMMEDIATELY start the engine.

Replace AC fan motor now car doesnt turn over right away.


You can try this to verify that the starter is good or bad.

Starter Testing Starting System Voltage Drop Tests NOTE: The battery must be in good condition and fully charged prior to performing this test.
There are three area of the starter motor circuits that voltage drop test can be performed on. These include:
  • The starter feed circuit
  • The starter ground circuit
  • The starter solenoid.
Starter Feed Circuit
  1. Disable the fuel system by removing the fuel pump fuse or the fuel pump relay.
  2. Verify that the vehicle will not start.
  3. Connect the positive lead of a voltmeter to the positive terminal of the battery.
  4. Connect the negative lead of a voltmeter to the starter B+ terminal.
  5. Turn the ignition key to the START position and note the voltage displayed on the voltmeter.
    • Ideally, there should be no more than 0.1 volt drop for each connection displayed on the voltmeter. No voltage should be consumed by the vehicle wiring
      1. If the battery cable connects directly to the starter motor there should be no more than a 0.2 volt drop measured
      2. If the vehicle uses a starter solenoid between the battery and the starter motor terminal there should be no more than 0.4 volt displayed on the voltmeter
Starter Ground Circuit
  1. Disable the fuel system by removing the fuel pump fuse or the fuel pump relay.
  2. Verify that the vehicle will not start.
  3. Connect the positive lead of the voltmeter to the case of the starter motor.
  4. Connect the negative lead of the voltmeter to the negative terminal of the battery.
  5. Turn the ignition key to the START position and note the voltage displayed on the voltmeter.
    • Ideally, there should be no more than 0.1 volt drop for each connection displayed on the voltmeter. No voltage should be consumed by the vehicle wiring
      1. If the battery cable connects directly to the starter motor there should be no more than a 0.2 volt drop measured.
Starter Solenoid
  1. Disable the fuel system by removing the fuel pump fuse or the fuel pump relay.
  2. Verify that the vehicle will not start.
  3. Connect the positive lead of the voltmeter to the case starter B+ terminal.
  4. Connect the negative lead of the voltmeter to the lug (the starter M terminal) that connects the starter solenoid to the starter motor.
  5. Turn the ignition key to the START position and note the voltage displayed on the voltmeter.
    • Ideally, there should be no more than 0.2 volt drop across the starter solenoid displayed on the voltmeter.
In general, there should be no more than a 1.0 volt drop throughout the entire starter motor feed and ground circuit. Any voltage drops measured in either the feed or ground circuits after connections have been cleaned will require replacement of the affected battery cable. Typically, any voltage drops measured in the solenoid are repaired by replacing the starter motor.

I looked at all the steps for replacing the blower motor...they should not have messed with anything that would have affected the operation of the starter.
