ANBU_fto · Post by **ANBU_fto** » Tue Aug 01, 2006 1:56 am

hi guys

finally got my FPR installed!!!!

BUT!.... the car is acting all weird on me!

like when i start the car... it now takes a while for it to start.... if you know what i mean. like i have to keep turning the key to the "starT" ignition and hold it there for a long time... and it doesnt sound to healthy....

help...

i heard thats common when u install a FPR...seems wierd to me. However since an FPR is vacume sensitive at start-up I can only assume it takes a while for it to get going. depending on what type, with a static FPR and u increase the idle pressure maybe it has some issues actualy delivering the fuel to this pressure when the car is not running.

Recommend doing an ECU reset first. If that doesnt fix it, check the fuel lines going in & out of the regulator - they could have got them on ass about.

Remember FPR at end of fuel rail, not the start.

yep... my ignition turned to shite after installing the FPR as well
only on cold start though... warm start is no trouble at all

my new optima yellowtop is turning it over quicker now...
and i'm still waiting to see whether new plugs & leads will make an improvement...
but to my knowledge your ignition is never going to be as good
as the stock FPR after you upgrade it

10??

It should be putting something like 42 psi in....

i think it was pounds, ten pounds... not sure... ill have to try it again.

thanks guys!

Found the stock figures:
2.7 bar (40psi) with the vacuum connected (standard)
3.43 bar (50psi) with the vacuum disconnected (wide open throttle)

lol if its on 10 pound (same as PSI) then thats your issue...no fuel

if its 10 bar then ffs u have too much

is it rising rate...make it comes good but seems like its too low to begin with.

Bennoz is right 35+ would be the norm.

42psi on vaccuum is good.
Assuming its rising rate, it will go up with throttle.
Anything less than 35 is risky for sure. Car would run lean and damage your engine.

So where did you have your dyno done, it would be intereting to see what other member might get at the same place.
