Starting....

Recommended Posts

These last few days I've had some bother starting the car - sometimes its can take 7 or 8 turns of the keys, sometimes first time!

 

Fuel pump primes, turn key and all the you hear is a big click.

 

Its not temperature related as this morning after it has been standing for 8 hours outside it was fine & started first time.

 

Any ideas?

 

Regards,

 

Gaz.

Click is probably starter engaging but lack of battery power prevents the engine from turning?

Do the cabin lights or dash dim when this happens? Normally indicative of a poor battery.

 

Maybe the weather has something to do with it? I know you think not but the last few days it's been freezing but here in south midlands it's 8degrees outside now so it's a warm day compared to yesterday which was -1. This can put an excessive load on a starter and battery.

 

To improve efficiency of the starting system make sure there are no deposits on the battery terminals. (Remove battery, clean terminals and replace. Then smear grease onto the terminals to insulate them from corrosion.

 

Ensure you have a good (if not new) battery. ake it off and charge it up. Winter is the typical time all slightly run down batteries give up.

 

If you have a voltmeter you could try starting it and watching the voltage drop. Probably quite a bit if a few cells have been damaged.

 

It could be a sticky starter but I'm not that mechanically minded so I'm not sure if it's a pre-engaged type or not?

 

Finally the fact it takes 7-8 turns of the engine to start it is also indicative of bad battery and/or bad plugs.

Replace the plugs with new ones. I think spark plugs only last about 5K or so. (Depending on abuse)

 

Mine are due for renewal and I get long start times. But I know my battery is brand new.
