02 Ford Mustang Won't start - battery is fine?

Before spending any money attempting to fix what might not be broken, just read this.

If you initially hear a clicking sound when trying to start your vehicle, that’s your starter trying to turn over the engine without receiving enough power from the battery.

It doesn't matter if your battery is brand new; if the terminals are dirty inside it won't transfer enough power to start the engine. It will allow the dash lights and radio to work, but not enough power to start the engine.

Your battery terminals can look bright and shiny and you wouldn’t even think they could be a problem.

Remove your terminals and look inside them. More often than not, you’ll see a dark build up inside them. The dark build up is oxidation which can block most of the current flow to your starter.

Some also assume that since their interior lights work, that their battery is not the problem, it isn't, the terminals are the problem.

It takes just a fraction of the energy to run lights as it does to start an engine.

Here’s the fix:

Clean all mating surfaces of your battery cables inside and out. Clean the terminals inside by either using a battery brush (you can get one at any parts store for a couple bucks) or a pocket knife.

First brush off the outer surfaces, remove the terminals and clean the inner surfaces until they’re bright and shiny. Now clean the battery posts the same.

(For side mount terminals, brush the exposed surfaces, remove the terminals (negative first) then clean the surfaces that mate to the battery.

All surfaces should be bright and shiny. Reattach cables, tighten them and start your car.

Note: You may need to re charge your battery if it's run down.

if the battery is good and the terminals were cleaned then it could be the solenoid. the solenoid is what kicks the starter in for the engine to turn over and start.

check that the battery terminal are tightly secured to the battery, then chase down the positive side to be sure that it is tightly secured to the starter cylinoid, then chase down the negative side to be sure that your ground is secure... sounds like a bad connection to me..

starter solenoid or battery

STARTER CLICKING,IT DIED.......
