2 Problems I Cant Figure Out..

[Hendrickavic]

hey guys i have got 2 problems i ant figure out,

1. i belive is a boost leak or turbo related noise, i have checked all vac hoses and cooler piping but no luck. it is a loud hissin sound but the car still dose's but sounds a tad different. i have tried a few mechanics but they dont have any equipment to find a vacume leak etc..

2. when i put the car on ignition sometimes the fuel reg whines, and some times when u start the car it wont start straight away, then the revs will bounce round a bit and smell a tad like fuel.

Cheers, guys!

the noise on startup may just be the fuel pump. even my stock one was hearable.

fuel pump is at the back of the car, this is coming from the fuel reg.

Ive noticed this as well since I have fitted a higher flowing fuel pump. It sounds like a vibrating type noise coming from the fuel reg. Not sure why this has started to happen now, maybe the extra amount of fuel flowing through it causes this. Also similar problems with revs, but reset the ecu and see if it improves. Mine stabilised on start up quicker after the ecu was reset.

does the vibrating noise from your reg only happen when your low on fuel. my mates does this but only when he is low on fuel, he's running and aftermarket fuel pump setup and we think its sucking a little bit of air to start with.

have you tried looking for obvious gasket leaks, ie: Manifold leaks.... Piping leaks...

genrally can only hear it on idle the fuel reg as its a humming noise. when the bonnet is shut u cant really tell. ive checked for all vacume leaks like everywhere n cant find anything, when you let of the throttle and it flutters it has changed the noise of that and now sound a bit hissy its hard to explaine ive tried 2 workshops but no one knows what to do, is there anyone that can actually help me in east melb that u guys know of?
