Answer First, be absolutely certain that the battery is ok. Try a jump-start using some good cables and someone else's vehicle battery with a good charge. If the starter still won't engage and you're hearing the clicking of the starter solenoid then just about the only thing left is the starter. If you haven't replaced a starter before, either have someone do it for you or get a friend to help who has a little experience. It isn't a difficult process but there are a few steps that demand experience.
Be sure that both ends of both battery cables are clean and tight.
A low or dead battery will have this effect. There is enough juice in the battery to activate the solenoid in the starter (causing the clicking sound), but not enough to turn over the engine. A jump start or a replacement battery may be needed if the battery is no longer capable of holding enough of a charge even when being jumped.
If the starter is clicking when you turn the key then the relay is not the problem, more likely is the battery and starter wire connections. Take them off and clean them before putting them back on ( have the battery checked ) corrosion will cause the symptom you described, however there should be a starter relay in the engine compartment fuse panel. If the truck is a standard transmission, it could be the Neutral safety switch, which is located under the clutch pedal. However, most likely it is the solenoid on the starter, I just had the same problem, time for a new starter.
Generally, if a car engine will not turn over without a jump start, the battery is not charged. Either the alternator is not charging it, or the battery has failed and will not hold a charge. Since you have replaced the alternator, that leaves the battery. You can have your battery tested at an auto parts store before buying a new one. It is also possible that there is something draining your battery while the engine is off. The clicking noise from the ABS indicates possible electrical system malfunctions that are best diagnosed by a professional mechanic.
The clicking noise is most likely relay chatter. If you turn the key and hear a clicking noise and the engine does not crank, this usually a sign of a low battery (or a short). Check the battery first. If the battery is good there may be a short in the electrical system. Start with the ignition switch. Remove the four screws on the bottom of the steering column. Then lift off the top half of the steering column. Inspect the wiring and try to tighten any loose connections. Make sure the pos. & neg. battery leads are in good order (especially the neg. lead.)
the battery is a part of the vehicle as is the engine.
clicking noise when trying to sart engine usually indicates a flat battery.if the battery is not the problem ,the starter motor needs repair.
check if your battery is low than usual ..might be alternator problem
Does the engine turn over and then make the clicking noise while trying to start, or does it not do anything but make the clicking noise when you turn the key. If its not turning over at all then it might be a battery problem, Try cleaning the battery terminals, and/or charge the battery, Could also be the starter solenoid, but start with the battery first.
The clicking can signify a weak or dead battery. Make sure the battery is fully charged to start the engine.
Battery, starter, starter relay solonoid, or a charging problem i.e. alternator or voltage regulator causing battery to discharge. Or bad battery cable connection or dirty or loose battery cable connections can cause this problem. Need to investigate & narrow it down.
Low Battery
The Battery is shot and you need to replace it.
AnswerIs the clicking sound from the engine? Try to check the oil.If this is happening when you try to start the car, it is most likely a weak battery or a bad starter. Oil would not have anything to do with this problem
A clicking noise in the engine of a 91 Ranger could indicate a problem with the valves. A valve lifter in the engine may be worn or stuck.
have you replaced the battery? It sounds like an electrical problem. The battery needs load tested... which can be done for free at autozone, advance auto parts, etc. Also check the starter soleonoid... should be located either on passenger side of engine compartment or on the firewall somewhere... simple/cheap fix if that's the problem
Weak battery? Loose or corroded battery cables? Starter solenoid?
could be bad cells in the battery, but my bmw ended up having a seized motor, starter was engaging and clicking because it couldnt turn the engine. try putting a socket on the engine crank pulley to see if engine will rotate
