'More' Cold Starting Issues
Hi all,this is a strange one to me..
My 95 WRX wagon always seems to fire up from cold..
Its had a new battery, new coolant temp sensor, replaced maf, new plugs, new lambda..
Anyway i let the pump prime, then turn her over which she does fine..but then it really hesitates and splutters before getting up-to cold revs(about 2k)
But what i have noticed is...if I put the battery on charge and then turn the key it fires up without any hesitation whatsoever!?!
Anyone help me on this please??

Anyone have any alternative suggestions as like I said it never struggles to turn over just really hesitant on cold starts..wondered if it may be an earthing fault perhaps?

I have the same problem mate changed the coolant temp sensor for a secondhand 1 and still does the same changed the fuel filter plugs.still the same next step think it might be a fuel pump to rule that out.thinking of buying a new coolant temp sensor and trying a new one.also changed the crank sensor for a secondhand one and thinking of getting a new one as well just to rule that out.going to get some new colipacks aswell as was told they could have some starting problems.
If it not one thing its another.
If I get it sorted I will let you know.
Forgot to add had the battery tested and it was full of life rules that out aswell.
Thismorning mine just struggled really bad and had to turn it back of as it sounded unhealthy it made a pop sounded like a miss fire kind of sound.
Will keep you posted.

Cheers for the feedback mate, my fuel pump is good..not to mention its a walbro so no shortage of fuel..il give my coilpacks another check over as their maybe a hairline crack underneath the rubber boot..
One other thing to add with my scoob is I always throw a cel on startup (code 45) but i dont think this is related to my problems..but it is another thing to sort out!
