Car won't start

[Conor]

Hi all,

The wife's car won't start - the starter motor is turning over but the engine is not starting. I think the battery is OK but I am charging it up just in case.

I checked the oil level and it's at the bottom of the dip stick - the nobbly bit.
The colour is a bit dark (I'm a biker myself so I'm used to well clear oil in my R6 and Fireblade).

She says the engine management light has been on for a while, and was going to drop it in to the service place the next time she was at home in her parents.

How hard is it to change the spark plugs and the oil?
Any how-to's on this site?

I'm not very mechanical, but I've serviced the R6 a few times, as well as other bikes, so this should be doable.

The engine management came on a couple of months ago, and the issue was down to the brake disks, once they were replaced it went away.

The car has 127,000 miles on it....

p.s.: how long does a "normal" charge take on a car battery? I have one of those halfords 1300cc car battery chargers. My bikes only take a couple of hours with the bike charger, but no idea about a car battery.

Cheers lads
Conor.
