Fords use under hood mounted starter relays. They look like a mine withe 2 large threaded posts abd two small threaded posts. Ignore the two large cable posts. If only one small post has a wire on it, remove wire and try to start engine. If no crank, put back on and try cranking. If it cranks then that is the wire you will put juice to with the other side of the in hand momentary button" connectected to the hot big past. Battery cable big post. Note! momentary button only. be safe, you will be too far from the brakes. Always block wheels. set parking brake. make sure trans is in neutral or in park Do not use remote starter while standing in front of the vehicle or while under the vehicle.

2002 Jeep Liberty starter "clacks" about every 2-3 minutes even when the motor is shut off and key is out of the ignition.

Does your vehicle have a remote start? Its possible that the remote start is malfunctioning. I had a vehicle with similar issues, and I didn't even know it had a remote start. (The previous owner had one, but had never told me about it, or given me the remote for it.) If you have a remote start, it should be located under the dash, next to the steering column, or firewall, or under the drivers seat. Disconnect the wiring harness from the remote start if you have one.
If you are sure you have no remote start, or if the problem continues after disconnecting it, then follow these steps.
1. Locate the small diameter wire going to the starter solenoid. The starter solenoid will be on the starter itself. This wire will be much smaller than the large wire that comes directly from the battery. This wire is is likely fastened with a round crimp connector and a philips head screw. Or it may be a clip on plug.DISCONNECT THIS WIRE. If the "clacking problem" continues with the key off, when the wire is disconnected, then you can be sure that the starter has a problem. If the problem stops (Of course it won't start either) Then proceed to step 2.
2. At this point you may want to take it to a professional who has the wiring diagrams to properly troubleshoot. But if you are up to it, Hook the disconnected wire back up to the starter, and locate the wiring harness coming from the key switch and disconnect it. If the "clacking" stops, replace the key switch. If it doesn't, then you have a short, or wire harness problem. At this point you probably need a wiring diagram and professional troubleshooting experience to proceed further.

2000 chev wont start at key

From the ignition switch there is a yellow wire that is for the starter. probe it when trying to start. If you have no voltage replace the switch. Also, I believe there is a fusible link in the wire by the starter. It will be a different color than purple. Probe on the back side of it to see if there is voltage at start up. If so, replace with the smae color link.

Ignition switch

The switch can be tested with a multi-meter to see if it is the problem. The switch will have a hot at all times wire going into it. If the switch has power out on the start wire with key held in crank, or if there is continuity between the power in wire terminal and the start wire terminal (on the switch side of harness connector) when the key is held in crank, then the switch is good. Check the neutral safety switch, then the starter relay, then the starter solenoid for a fault. You may need to see a wiring diagram to find the color of the start wire coming out of the switch. A single wire from switch to the neutral safety switch and on to the starter solenoid.

Usually one is small enough to fit on the small terminal and the rest fit on with the battery cable.
The small purple wire from the key switch goes on the terminal marked S.
You could do a continuity test and check it with the battery disconnected by checking it back to the neutral safety switch.

At the base of the steering column in a connector, you should be able to check continuity there. Look up what color wires run from the key switch down

It sounds like the ignition switch again, thats the only source for the starter solenoid to power up. I'd disconnect the power to the starter solenoid (ignintion input small wires, not the battery cables). Jumper the battery again, check for power on the solenoid for the ignition feed, if it has power then yes the ignition switch is bypassed somehow. I've seen issues with the back side of the connector going to the ignition switch where the wires are bare from being flexed, the insulation breaks and wires touch each other. Carefully check the condition of the wires going to the ignition switch, if good replace ignition switch again.

Ignition has no electicity going to it everything else works and we can start the car by bypassing the ignition is there a fuse somewhere we aren't seeing or a wire or is it the key part does anyone know...

Hi, there should be a fuse and a Starter Relay located in engine compartment, driver side, front side of strut tower, mounted in relay block on fender wall.

Different manufacturers use different abreviations for circuit fuses and relays, I recommend to check all of them.

Also, check if when key is in RUN, power is getting to the Starter Selenoid Mounted on top of the Starter thru the skinny wire (There is a FAT wire coming straight from the battery, that one is HOT at all times,) if power is coming in, REPLACE STARTER SELENOID, if no power present, REPLACE IGNITION SWITCH.

I've includded a troubleshooting chart, instruccions on how to replace STARTER SELENOID and some pictures to help you better identify and fix your problem. (I always think is better to have too much information than not enough) : )

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.


  1. Disconnect the negative battery cable.
  2. Remove the positive battery cable from the starter.
  3. Label and disconnect the solenoid electrical connectors.
  4. Scribe matchmarks on the solenoid and drive housing to ensure proper solenoid installation.
  5. Remove the nut and field coil lead wire from the solenoid.
  6. Remove the screws and solenoid from the starter.

To install:
  1. Lightly grease solenoid plunger.
  2. Install solenoid to starter aligning housing matchmarks.
  3. Install screws and tighten securely.
  4. Install field coil lead wire to solenoid and secure with retaining nut. Tighten to 89 inch lbs.. (10 Nm).
  5. Install the solenoid electrical connector.
  6. Install the positive battery cable. to the starter. Tighten to 89 inch lbs.. (10 Nm).
  7. Connect the negative battery cable.
Let me know how it worked out, Good Luck,

Envoy is getting power on key turn, but it will not turn over. I know it is not the battery. I was installing a remote start and once I started it,with key, it ran rough so I took all remote start parts...

Most likely you either connected one of the wires in the steering column/ignition switch wrong or didn't connect one of them. The start circuit has contacts to make sure the transmission is in either Park or Neutral, and also has contacts on the ignition switch. Since you probably didn't disturb any wires on the starter or solenoid when you wired the remote start, the best place to look first is the places where you added the remote start.

How to install a remote car starter

The remote start should come with instructions, you will need these especially for the diagram of the units wiring harness.  It will need to be wired into the ignition key on wire, the ignition starter wire, power and ground, and usually the brake light wire, and a hoodpin disable switch that will come with the unit.  Also most manufactures will have a website with vehicle specific details like color and location of each wire on the vehicle.  hope this helps.
