trouble turning over engine, Subaru Impreza 2007

Have a 2007 Subaru Impreza, normally when you start the car you get a couple of whirr, whirr, whirr, but every now and again, maybe once every few days it takes longer to start, and can usually get a good 4 - 5 seconds of whirrs before it starts. Doesn't only happen at cold. Battery replaced 2 months ago - this problem started occurring 3 weeks ago. Oil change, oil filter and air filter replaced 2 months ago. Spark Plugs were done around 12,000km ago. I have been told at the last service that my alternator belt needs replacing, but haven't done anything yet. It doesn't sound like a battery issue, as the car seems to have full load when whirring. The only thing I have heard is thick oil could cause an issue, and at my last service they put a wynns oil additive which was almost like a thick sludge. Fuel Pump hasn't been replaced for 35,000km but it is still within service schedule. I have been through 3 full tanks of different fuel just in case it was bad fuel.

ok, I have to ask, whats the issue, do you mean it turns over at the right speed but doesnt fire straight away?
sorry but whirr, whirr`s arent a great technical term.

sorry, the usual noise the car makes as it is trying to turn over but sometimes it will just take up to 5 seconds to fire.

Re: trouble turning over engine, Subaru Impreza 2007

when you first turn the key and the engine lights come on can you hear the fuel pump prime ?

Mine does that sometimes if I turn it straight on; I turn the key to on wait a couple of seconds till it clicks( not sure what clicks either its the ecu or turbo timer perhaps) then it fires up straight away. Simple but it works for me cheers mate

Re: trouble turning over engine, Subaru Impreza 2007

thanks, been to the dealer this morning and they said more than likely the fuel pump is the issue. They are giving me a quote on it when they hear from the supplier next week, but can anyone give me a guess what I am looking at for labour, and parts? Dealer will more likely be genuine but I would go aftermarket.

Re: trouble turning over engine, Subaru Impreza 2007

you can get a replacement (aftermarket uprated) for under 70, there are a few "How too`s" if you fancied DIY.
