Hard Starting

**BlackVr6ix** · 22-12-2006, 08:26 AM

Got a problem that has just manifested itself in my car.

get in and try and start. Fails first time, try again fires straight up 90% of the time.

and Tim if you say in tank fuel pump i'll kill you hahaha.

the pumps get very noisy when they go from my experience. I doubt it would be that.

there isnt ANY noise coming from the back as far as i can tell.. it feels to me that it is loosing fuel pressure initially as once the car starts it runs fine, the idle is a little jittery but it hasnt lost any power.

Could it be the FPR?

i am having the exact same problem with my car... Does it tend to start first time if the car is warm?

I have been told that it can be an injector issue...

Totally random, although it does seem to be a little better after injector cleaner.

it is worse on hot days then cold days.

im getting my injectors carbon cleaned soon so ill let you know if that helps.

check all ur fuel line's and injectors and maybe ur distributar or leads but not sure

**wakdog** · 22-12-2006, 12:41 PM

wouldnt be leads as if there was a prblem with them he would get it under load, not just on starting, VR6s dont have a distributor in australian delivered models, rather a coilpack, but again i highly doubt this to be the origin of the problem.

Wouldnt hurt to do the fuel lines. Could be clogged up with crap, so give them a flush to clean out all the crap. Have you tried changing the fuel filter?

I`d suspect one of the sensors on the front of the thermostat housing. Probably the blue 4 pin one. or the yellow one. Hard to guess though. Better to plug it in to a service thing and get it scanned. I`d do if for you if you were nearer.
