Why won't it start?

You've either a dead battery or dirty terminals. Clean the terminals at battery and charge it up if needed. First try jumping the battery from another vehicle. If you get power from the jump, then it's what I told you.

Dead battery

Dangerous practice to try & jump a dead battery

The battery cables could be loose at either end or corroded internally

Most likely the battery is worn out, if original to car
since it was new, or the starter solenoid is worn

You do not want to jump any vehicle made after the
year 2000 or your asking for possible problems with
todays electronics.

You need a good battery that has been tested & fully
charged, then only jump with a jump pack,not another car

You could have blown the main fuse while doing the jump start. Also check the fusible link on the power battery cable.

the clicking sound is the starter relay check battery starter motor and this clicking relay hope this helps ivan

sounds like dead battery. did u try to jump start it. If u did all this it is possible one of the main fuses is blown. Check with a test light.

whilst you are trying to jump start it check if you jump leads are good and powerful enough to sent the power to your battery,check if your battery terminals are clean enough to accept the power given,or is your battery not completely dead and even you are boosting has not the power to increase the needing one to start and is just for lights only?

The voltmeter should only go as high as 14-15 volts when the engine is running. I would check for a poor connection between the battery and starter.

Sounds like your battery is just too dead, has enough juice to light up the system for a minute but cranking drains it and if it wont charge then deff fried, you could try removing the battery and starting the car with cables to confirm the starter still works. If a bettery is too dead then when you are jumping it, it takes to much of the power just trying to get through the battery.

Hi there !

I won't say its an alternator problem because the alternator only charges the battery when its on, And it should start with the jump cables even if the battery and the alternator are bad. your Issue is not clear. Does the car start when you jump it ?

is your terminals clean on your battery sometimes a battery is so dead it cant be jumped when you say its not starting again do you mean the truck dosent even turn over when trying to jump or engine turns it just dosent start
