COmputer, loose battery, defective battery/volt amps or loose wiring harness/ wires grounding out somewhere
Corroded battery cables, loose battery wires at the starter, water in fuel tank, clogged fuel filter
A weak battery, loose/broken wires making a short, defective sensors that monitor what the gauges are displaying
check your battery connections (maybe loose wires)
What makes you so sure it's wires? Any loose ground related to the cranking system can cause it, faulty spark plug wires will also do it.
No. If you have a clicking noise when you try to start your car there is a couple of common causes. You may have a loose or weak connection to your battery. Try checking the battery wires to ensure proper contact with the battery. The other could be an issue with the fly wheel. If the fly wheel is missing teeth, it can have a difficult time turning with the starter.
Corrosion on the wires, bad starter or starter solenoid, worn flywheel or flexplate, many things. Even just corroded battery terminals could cause no start.
To start with, how do you know you have a full battery? If your battery has a one or two bad cells in it, it will give the apperance that it is fully charged but actually is not. If you know for a fact the battery is good, you may want to check all your wires going to your battery. Look for corrosion, broken or loose wires or even a loose clamp on one of your posts. Lastly and probably most extreme case, your starter might be going out. If you can reach it, knock on it a few times with a hammer, or something else in that nature BUT BE SURE NOT TO HIT ANY WIRES OR LINES!
It probably wasn't the ends to begin with. Start looking for loose wires starting with the ends if the battery tested good.
Start with the battery terminals and connections on the other ends of the battery wires. Check the battery itself as a loose plate in the battery could be heating up and shorting the battery for a moment causing the problem.
there are many things that can cause this problem. bad spark plugs / wires bad alternator ignition problems loose or corroded battery conection incorrect timing
Start with the power chain. Since nothing works check the battery. Pay careful attention to corrosion under the connectors and loose wires going into the connectors. Check for loose wires at the starter as well. If Most likely its a bad power connection.
