Weak Start

[Sol32]

Hey guys,

This really isnt that bad a problem but it's doing it more and more often these days... no matter if the car is warm or cold... Ill turn the key and she'll kick over and instead of starting shooting nicely up to 1000rpm, she trickles in... hard to explain, its like theres no bounce to it. Once it passes that, she idles and drives fine.

The power FC is currently tuned to v-power racing, the 100octane ethanol stuff... Ive heard that this is more viscous than say BP ultimate and something (lines, injectors?) is getting clogged. Could this be the problem?

Thanks in advance

Andrew

sounds like my r32, it sorta struggles to start up and sometimes needs a press on the accel to get revs up. Not sure if its same prob

[Adriano]

Does it do it worse hot or cold?

fuel filter? Its starving for fuel till it gets going, I'd say water in the filter.

well to be honest it only started after the alarm was installed - and he MOVED my fuel filter. I'll swap it and see whats happens. Thanks heaps

my 32 does it too only when its been sitting for a day or so and its a old morning and u start it. not cool

More of the picture------its going to be filter OR alarm related. Filter is easier to check for now.

yeah. pretty common. id say with the age of them the auxilary air valve is stuck. or the idle motor is a little sticky to.

yeh my r32 does that too but only after it has been turn of for a while...

R32's tend to do this.

My R32 has been doing it for years and this problem is no different on my new motor.

Nothing worth worrying about.

My brothers R32 does it as well.

Buggered if i know why.

possible the Air control valve dirty, my r33 does it all the time when it's cold i just have to push accelerator a bit, the rest of the day it starts perfectly fine.

I read somwhere, that common cause of starting problems is due to the engine being cold. Metal expands when its cold and this causes the compression in pistons to have leaks hence the poor idling?

Seeing as R32 is an old engine, it would be worn and be more prone to leaking etc etc.

Not sure how valid this theory is haha.

the anti drain back valve in the fuel pump?

[DjeMz]

Where is the fuel filter?

I wanna take mine off n have a look, what steps do i need to take??

me being me, i will break something n all the fuel will come out

Wherever you read it has their facts and physics wrong

Nothing expands when its cold, it shrinks

Things expand when they're hot
