Hi,

the first thing that I would check is to make sure your battery is fully charged or try and jump the battery using another car battery.
if still no go then I would say that your starter solenoid is bad.
while checking the solenoid/starter double check to make sure your block to body ground cable is secure.

hope this helps,

chris...

SOURCE: intermittent no start. Battery/charging system ok

If it intermittently starts, the battery/charging systems are ok and you hear the relay click, I would suspect a starter going bad. When the engine won't start have some one hold the key to the run position (as if you were cranking the engine) and tap lightly on the starter housing with a metal hammer. Be careful not to hit any of the wires on the starter. If the engine starts cranking and or starts, the starter is going bad. Chances are the armature is burn't or the brushes are worn out. It is usually cheaper just to put in a re-man starter then trying to rebuild it. And since the car is relatively new, chances are you won't be able find parts for it. Now a word of caution here, when you are tapping on the starter be careful not to be next to any moving parts (pulleys, belts, etc) since the engine may start. Also another thing you could check for is loose power cables. You might want to try this before checking the starter because it's easier. Try wiggling the battery connections, follow the negative to ground and wiggle and do the same thing with the positive cable to the starter. You should not be able to wiggle the connections at all. If you can the connections will need to be either tightened or the connector replaced. This should solve your problem. You could also try swapping your relays around and see if this fixes it (just because a relay clicks dosen't mean its necessarily working right.

SOURCE: starter relay clicks when you turn ignition key on

I would think bad starter. Remove it and have it tested to find out. It could also be the starter solenoid gone bad.

SOURCE: no start condition new battery , good starter,

no starter relay is always at the fuse relay box at the engine compartment. The relay that you hear is the relay for the accessories to turn off the power during starting position.

2006 Ford Expedition will not start this morning, battery checks 12 volts, will not do anything when turn key to start position

You can jump starter relay to see if starter will crank the engine. Pull the starter relay, use jumper wire between terminals 30 and 87, terminal 30 is hot all the time and there is a fuse, the starter motor should crank the engine. If you try that make sure tranny is in park or neutral and parking brake is set. Two voltage circuits at starter motor, one is hot all the time. The other goes hot when relay is energized. The starter motor grounds through engine block. Battery positive and negative connections are important.

Ignition switch turned on all power is drained and a buzzing sound comes from the dash driver side truck won't start

This sounds like one of two things. The buzzing is sometimes a key in the ignition reminder in lieu of chimes, or the bad Relay is vibrating.

Sometimes when Relays go bad the contact points melt together. But what most people do not realize is that Relays operate in a domino sequence and have 2 or more sets of contacts in each Relay. One relay activates a second relay. With the points frozen in the first relay, the second relay in domino sequence is turned on with no job to do. The spacing between the contact points and its coil continue to buzz because it is not able bite into its matching contact.

First, you can get free Powerbox diagrams by registering your truck on Autozone.com. The wiring diagrams are also free. This will give you a clue to which relay goes where and does what.

Find the buzz. The vibration should be coming from the relay that is the problem, or connected to the problem. If you think about it, a stuck Relay can drain the power. The source of your original problem.

Have you recently used the trailer plug? What does not work on the truck? Horn? Door locks? Window motors? Seat motor? Rear window?
Was something plugged into a power outlet? Cell-phone, I-pad, etc.

Finally, disconnect and fully charge your new battery. Ford alarm systems are very, very sensitive to low power. Unplug the alternator to see if the noise is coming from bad Diodes grounding the alternator.

I hope my solution helps and would like to know the results of this mystery sound to share with others.

My 1993 Dodge Caravan won't start. There's a clicking sound under the hood when I turn the key. I was told to reset the map sensor. Although, I don't know how. I put in a new starter yeste

Do not go back to any " mechanic" who told you to re-set the map sensor. Those are some baaad mechanics, giving you a schuck job. That is outrageous . If the clicking is coming from the relay and fuse center by the battery, you probably need a new $10 starter relay. If the clicking is coming from the starter solenoid on the new starter you put on, then it's not a bad part, but likely a loose connection at the battery, or at the starter where the big cable wire attaches. Are your battery cable connections corrosion-free and clean and tight? Did you happen to remove a ground wire and forgot to re-attach it? Check your battery ground, the negative cable where it attaches to the frame of the car, or to the engine. That should be clean and tight also. If the starter solenoid is clicking, it means that the starter is getting a signal from your ignition switch to turn the starter motor on, but the starter motor is not getting full battery power from the battery to start turning and thus cranking the engine. The starter motor gets its full battery power from the positive positive cable. One end is on the battery, and the other end is on the starter. If your battery is still charged up enough to start the car, all connections are tight, you have a new starter, and the solenoid just clicks, it may be a bad battery cable.
I will stop here, and wait for your response . Hope you find it, just keep looking. There is no such thing as re-set the map sensor, period.

Car won't keepidel1989 300e Car won't keep idel, starts up runs for a while but cutsoff

first ensure your spark plugs, wires, cap and rotor/coil packs are in good shape. once thats done check for a check engine light, sometimes they come on then go off but a code will be stored regardless. once you have made sure your getting good spark and there are no trouble codes the issue is most likely a dirty throttle body or fault IAC (idle air control) valve or throttle positioning sensor. hope this helps, good luck

1994 ford escort won't turnover, the fuel shutoff light comes on when you press the clutch. can push start and will run

soundsa like the starter or the fender mounted solioid is malfunctioning. Does anytrhing clich as you turn the key to start? If theirs no click at all you might look and the starter relay ( solioid) it's located near the battery and it has the positive battery cable connected to it. Also notice the most common no start is the battery cables aren't making good connection to the battery or the battry is too low as it may be low on charge. Have the battry tested or if handy to do see if it starts normally with jumper cables connected to a running car. If it starts just fine the battery or the charging system needs to be looked into. it it tris to start and crnks slowly and makes bad noises the starter is likly bad. If it had been starting just fine and this happened all the sudden the cables connected to the battery or the battery failing are the most likly.

Check your starter. It could be that or the starter solenoid, or the ignition relay. Also check to see if the battery cable is connected tight to the starter.
