traveling down freeway and car stalls at 100kpm,power light comes on and wont turn over,does'nt engage starter motor ???

Power light constantly on and no flashes.

more details on which car this is and how many kilometers?

 

any sounds before it quit?

 

any sounds when trying to start?

Is the charge on the battery good? If that is okay then check the voltage getting to the fuses in the dash area when the ignition is ON. If that is okay then check the starter circuit for a problem. The inhibit switch may be faulty. Hopefully this issue isn't due to a timing belt breaking.

Check the battery terminal connections.

Sometimes they can get corroded, and a light tap with a hammer or small rock will make a temporary fix.

new battery,300 000 k's, 2001 liberty,power to motor and starter not engaging solenoid,what ever the sensor is it's not allowing to start or override the fault?

sounds almost like a fusible link or some other major power issue.

 

maybe double check the battery cables and the small wire to the starter too?

Check all your grounds, if they are all still connected try wiggiling connections while key is on and see if you can tell any differance. Sounds like a faulty ground

nothing wrong with connections to battery, have checked all relays and fuses at boxes,fault not allowing the starter motor to engage,fault indicator (power light on at guage readout)

You say: "Not allowing the starter motor to engage".

Does this mean that:

- the starter motor spins, but will not engage the flywheel? or

- there is an audible 'click' from the starter solenoid, but the starter does not spin? or

- there is no sound at all from the starter motor?

starter motor has contact, but solenoid doesn't throw gear out to mesh fly wheel?

starter motor spins but doesn't contact flywheel, I think that the fault is overriding contact?

From what you state about the starter either the ring gear on the flywheel has a bad spot on it or the starter bendix is bad. Either way you need to remove the starter to find out the real culprit.

it has nothing to do with the starter motor,its to do with the fault that is indicated with the power light on, which doesn't flash to find the fault, bugger it,

I'm just going to take it to the mechanics and put an OBD on it,when it has been fixed i'll put the problem and the diagnostics up and then the steps to rectify the problem and the cost,

cheers Stan.

From what I know about the POWER light in the dash it has to do with the engine performance, not the starter circuit or any of the electrical system of the car. You stated previously that the starter was turning but the engine wasn't turning over. If that is correct then there is a mechanical problem with the bendix gear of the starter not engaging the flywheel ring gear. 

Broken timing belt !!!
