Flooding/Over fuelling

[adam 32]

i had a new pump fitted a couple of days ago and now the car doesnt start too well, it ticks over for about 5-10 seconds before splutteting into life....

i think its cos its flooded with fuel, whats the cheapest way to rectify this? is an S-AFC going to help or do i need a complete remap?

could it be that you need to prime the fuel lines before starting?

or you might need to get your fuel pressure regulator adjusted.

joel uses a bleed on his fuel line to controll pressure ask him .

what do you mean prime the fuel lines??

and my fuel economy is ****!!! but i guess its all part of the same problem.... AF's are hovering around the 10:1 mark

Your AFs are not helped by that Blitz ECU of yours; I assume it aint tuned for australian el'crapo fuels, aggressive maps aside.

Go buy an e-manage.

Go buy a fuel regulator.

Just switch the key to on and the pump will pressurise the line, you should be able to heart the pump work then stop, then you can start the car.

The new pump will have more pressure so when the other would not pump enough at high revs this one will be consistent, get it remapped and it will be fine.

if you had your car running fine before installing this pump,then i think youve done something that you shouldnt of.

The pump itself should be ok if that was the only thing installed.

Even if higher flow,the regulator is the part that controles the amount of fuel pressure your injectors will see,and will keep it at a constant 40-45psi at idle.

unless your regulator is faulty,it could raise the pressure and make it run richer(but you havent touched it,have you?).

Best thing to do is,put a fuel pressure gauge in line with your fuel out hose and see how much PSI your getting,and let us know.

Have you connected everything properly?(in -out lines)

once started,can you rev it and keep it idling

explane a bit more...

once started the car runs like an absolute gun!

no idling or fuelling problems at all

its just on start up that it wont start straight away, you turn the ignition and it ticks over for about 5 seconds then fires......

i know i need a remap as well but i cant afford it now as i just spent it all on the pump and a boost controller!
