Hi guys,

I've got a bit of a strange and intermittent problem when starting my car:

It's a 2002 UK WRX. 7/10 times the car starts perfectly and first time. But occasionally, and its becoming more regular, it doesnt want to start - the starter motor fires and the car tries to start, and sounds like its almost going to, but then then doesnt - The sound it makes is as if the battery is draining all the power and is about to die, so i'll stop, leave it 5 mins, try again and it starts perfectly!

Has anyone else had this problem?

The starter motor is doing its job, the battery seems to work fine, so I'm at a loss as to what it could be?! Spark plugs maybe?

Any help of advise much appreciated!

listen out for the fuel pump priming, if you cant hear it or its making stange noises its on its way out. This would cause the problem your having

Put digital voltmeter across the battery,check the voltage does not drop more than 2 volts while cranking.Put voltmeter from earth terminal on battery to engine casing crank,if a reading comes up bad earth,the same earth terminal to clean body panel crank,if reading comes up bad earth.
