An engine is unlikely to start if the cranking speed is low. If the engine is cranking at all it is unlikely the solenoid is faulty, however when a starter motor has an internal fault that causes it to attempt to consume more current than is available they have been known to buzz or hum while turning abnormally slow...

1996 Toyota tercel doesn't start doesn't crank


Well you may have more than one problem.
As far as cranking, a mechanic would check for voltage at the starter and trace back to the key switch. The key switch could cause both problems. There is also a neutral safety switch that could cause it not to crank.
You could also have a bad ground connection between the engine and body.

Hyundai accent 2001 will not start all lights work radio works heater fan works battery in 3 months old when I turn the key all i hear is a humming sound for about 1 min. than nothing. weather has be


The humming would be the fuel pump coming on. It should only hum for a few seconds, then shut off.
Your problem is with the start circuit from the battery to the starter, or from the ignition switch to the starter solenoid. Check the connections at the starter (the big cable) for tightness.
Is the battery charged up enough to turn the engine over? Check by turning headlights on and observe while someone turns key to crank. If they dim a LOT, then either battery is too low, or the starter is bad and needs removing for testing. If brightness doesn't change, then the circuit from ignition switch to starter solenoid is likely not working. Check for 12 volts at the small wire to starter solenoid with key in cranking position. If you have power there, the solenoid may be bad. Remove starter for testing. If no power at solenoid in starting position, then either the ignition switch is bad or the neutral safety switch might be the problem, or the wiring from the switch to the starter solenoid is not passing current.
Good luck.

Car wont start,seems like battery went dead


If the car doesn't start with a jump you might have a bad alternator. The alternator supplies voltage to the car once the engine is running. If the battery is dead, and the alternator isn't putting out sufficient voltage, the engine cannot run. Then again sometimes a car with an extremely dead or internally shorted battery WON'T start with a jump. Replace the battery and try again.

93 corsica not starting


When you turn the key to on, does everything come on, all the dash and warning lights?
When you turn the key to cranking, power is sent to the solenoid mounted on the starter, through a small purple wire. This is what engages the starter. But the path from the ignition switch to that solenoid travels through a starter relay and a neutral safety switch(for automatics) or a clutch safety switch (for manual transaxles). Check for power with a testlight or voltmeter at that purple wire on the starter solenoid when someone holds the key in crank. If you have power there, the solenoid is bad, and starter needs to come out to replace the solenoid. Doesn't sound like that, though. Usually they make a clicking sound when, or before going out. I think maybe the relay is bad or the neutral safety switch may be your problem(or the clutch switch if you have a manual).
Good luck.

Starting problem think it is fuel filter but not sure have blown filter out twice but problem keeps occuring would it be the pump? once it starts it runs well. Its a mitsubishi triton dual cab ute mk 2003...


Thanks for choosing FixYa and welcome to the site. Listen to hear if you can hear the fuel pump kicking on when you first turn the key. You should hear a humming sound for a second or two. If you do, it is working, If not, it is not working. If so, check your fuel pump fuse, relay, and shut off button if you have one. It could also be bad fuel injectors. You can pour fuel into the intake, if it starts, you have a fuel issue. If it doesn't, it shouldn't be fuel related then. If these all check out, if you don't have inside power, it is a connection problem with the battery or a bad battery. If you have power and there is a clicking sound, clean the battery terminals and post, check the connection. Make sure the battery is good. If you turn the key and there is nothing, you have a bad starter or starter solenoid. Check your ignition fuse also. If the starter is not getting the correct amount of power from the battery, it won't start. Make sure the alternator isn't draining the battery as well.

2001 dodge caravan clicks when trying to start


The clicking sound is coming from your starter solenoid. Which could mean your solenoid or starter or both are bad. But don't rush out and buy replacements until you have troubleshot the problem a little. First, try a jump start. If that works and the car starts, then either your battery is not putting out enough amperage to turn your engine over, which could mean your battery cables are corroded and not making good connection or your alternator is not charging your battery when the car is running. If it started, suggest you take it to an auto parts store and have them test your battery and alternator.

Now if it doesn't start when jump starting, you still need to do some more troubleshooting. Yes, it could be the solenoid and or the starter, but it could also be something internal to the engine. Take off the serpentine belt and try to turn the engine over with a large socket wrench. If it turns, then it is your starter/solenoid, if it doesn't then it is internal to your engine.

Car wont start, doesn't even turn over. battery is good though, boost does not work. think it might be the starter?


Its a good bet. Be sure the battery connections are good too.. Flip on the headlights and then try to start it.. have someone watch the lights.. If they go dark. You have a bad battery or bad connection. If the lights stay bright then you need to look at starter connections/starter/starter solenoid.

Have a 96 Corolla- won't start- just one click- have replace battery and cable connections are good. am thinking it's the starter cell gone bad...is this correct?


Most likely. If you are sure all connections are good at the new battery and alternator then it is either a bad starter or a bad fuel pump relay. To check the relay get under the back end of the car and have someone turn on the key, if you hear a
"humming" noise, then I would replace the starter.

1995 Nissan Maxima won't start, not battery.


You may have bad solenoid, starter/battery/solenoid connections, or gound.

Check voltage at starter solenoid when somebody turns key to start. That is where the starter switch, or relay, sends the voltage to pull in the solenoid coil through small wire. I think the solenoid is on the starter for this car, but it may be separate. Autozone has an excellent web site with car-specific repair guides and instructions. You should see 12V at solenoid every time the key is turned to start.

Check big power cable to starter that runs direct from the battery for tight connections. If you have a separate solenoid, then another big cable runs from it to starter. A loose or bad connection could be the culprit. Also check starter mount bolts. They need to be tight for a good solid electrical ground. You also need good ground from frame to engine. Its a long shot, but sometimes the ground straps come loose or burn. You can easily check this by measuring resistance between engine block and negative battery terminal. It should be zero or darn near zero (less than 1 ohm ?).

The solenoid is really a heavy duty swich to handle the high amp load to the starter. It works by a coil that pulls in the big switch. The coil operates from the starter switch and needs onlyt low current and small wire. If the coil wires burn up or there is a bad connection, it won't work. Hope this helps.
