my fiesta rst has a problem when u start the car up it is fine sometimes but then all of a sudden it drop below 1000 rpm splutter and loses its power and the car wont rev up properly. when i am driving the car it does not feel like the turbo is coming in and u can hear it spluttering from the exhaust then it will cut out sometimes can anybody help me please i have fitted a new fuel pump and sender but has not cured it

 

alright fella have you tried checking your plugs as it could be spark related try your plug gaps or check that your leads are not arking out cheers

 

You're guna have to start from the top on this one, as gup says check plugs and leads. You as may aswell give it a good service to eliminate as many things as you can.

 

get a gauge on the fuel rail and check the fuel pressure. Also check the voltage across the fuel pump when running and also at battery. anything less than 12v and you have no chance.

if this is ok check all pipes and fittings are tight in engine bay and from fuel pump to engine bay. have you also changed the fuel filter?

 

is it chipped? if so take it out and try it without it.

check for vac leaks and for the sake of a tenner i would advise a new fuel filter as its prob over due for one.

let me know what things you have checked/changed and how and we're go from there.

 

Thats it you just come storming in after ive done all the dirty work

I'm tellin Nicki about you

 

but i am the man who knows about FRST's ive had mine 8 years

 

In that case i wont be expecting to see any help posts or questions asked from you then

 

you dont do ya....

stop getting off topic, you do it all the time chav people will dread up replying as it will be the never ending thread

 

ok lads checked leads and they are fine i have changed coil pack fuel regulator and edddis unit still spluttering like a twat can't even get it to tick over now as for a fuel filter it has never had one since the 3 year i have owned it lazy i know will but one tomorrow and put it on thanks for the help

 

Sort it out, get a new filter on it and some plugs if they haven't been done

Could do leads aswell, don't be a scrooge

 

filters dont need changing very often, book says every 60k i do mine every 20k.

have you tried cleaning the ISCV out?

 

busy getting a fuel filter on now i have changed plugs and leads will clean iscv and let u know cheers

 

dont forget to de-pressurise the fuel system by removing the fuel pump fuse and cranking it over.
remove fuel cap to get rid of tank pressure too.

that way it wont piss all over the show when ya undo the filter

maybe i should of said about that before

let us know how ya get on.

 

You pussy, its only a bif of fuel man

Letting the side down or what

 

fuck off you , i had me fair share of fuel in the mouth, eyes up the nose down the arm etc hang on......... good point hows it taste daversturbo

only joking dave.

not letting the side down chav, just waiting for you to fill in what i missed

missed it that time round though ah , jay 1 chav 0

 

need a fuel pump lads anyone got one for sale

 

just sold one

i do have another in the shed i took out a mates car as he said it was fucked, but im sure it works as if i remember right i tested it at the time can check it if ya get stuck mate.
it might even be a uprated one as the connections on the top are different but theres no markings to say as such.

and if ya running beiges you need a uprated pump BTW mate.

 

yeah could u check for me please mate how much do u want for it are u registrered to paypal

 

anyone know if a fuel pump from a rs 1800 non turbo is the same as a fiesta turbo

 

Just looked on microcat and the Turbo pump appears to be the unique one

 

dont worry about microcat.

yeah the part numbers are different but they fit and work and work fine, a few people i know run xr2i pumps, and belive me your be fine, as the 2i and FRST use the same injection system inc the injectors, its just the regulator thats adjusted different so the 2i 1.6/1.8 ans rs1800 pumps will work fine.

if ya running beiges you need a uprated pump mate.

once i checked the pump i will let ya know., but i can only dry test it mate by buzzing it over on a battery

yeah i got paypal mate, as for price, once ive tested it ill let ya know and you can make a offer dude.

 

Sorry but i have to disgaree there the Turbo pumps are different! An XR2i one will not supply enough fuel.....

 

i believe they are the same mate cos i bourght a brand new one once for a xr3i cabby and when it came it had on the box xr2i/xr3i/rsturbo/fuel pump

 

dont mean to piss on ya fire mate but it does, trust me i have a few mates running 2i pumps in there FRST's i even runs a 165 chip, he's had it rolling roaded and fueling fine...

the 2i/frst pump is good for this, if ya going 195 chip its not.

anyhow, if you buy a after market pump the 2i and frst have the same parts numbers as its not the pump pressure that is different its the bottom part that differs a tiny bit

 

cheers mate great help

 

The turbo pumps have a sticker on them identifying them as turbo pumps though.......

And you look on microcat and the turbo pump is the one thats singled out. It may well work but you're blatantly raping it

 

na not raping it, both pump are able to deliver the same pressure

 

ive got 2 rs turbo pumps don;t know where your looking mate cause they have no sticker on them at the end of the day the pump is still running a 1.6 engine the turbo has nothing to do with fuel

 

the turbo engines do run the fuel at a different pressure, but this is adjusted by the regulator, not the pump.

 

safechav stop repling to these posts as u are talking poooooooooo i can smell u from here

 

That was a bit harsh

Jay, i know the pressure is regulated by the pressure regulator, i may look thick but im actually not

I'm sooooooo sure the pumps different. Its the fact of how much fuel the pump can deliver under full load, thats when it makes the difference, same pressure, but faster consumption!!!!

 

Just out of interest is it ofab or ofac not that it makes much difference but my mates did similar thing on an ofac one and was the map sensor. This is definitely unique to the turbo tho.

 

right, taken from auto data itself, these are the details for the pumps on the fiestas.



xr2i 1.6
delivery pressue 5.0 bar
regulated pressure with vac 2.3-2.5 bar

xr2i 1.8 zetec
delivery pressue 3.0 bar min
regulated pressure with vac 2.5-2.9 bar

FRST
delivery pressue 3.0 bar min
regulated pressure with vac 2.9-3.1 bar

all i could get on the RS1800 was regualted pressuer WITHOUT vac
2.5-2.9 bar

so you see a xr2i pump is fine for use, and really you shouldnt need to adjust the regulator just by changing the pump.

maybe the FRST uprated pump is a 2I pump

 

Hang on hang on, thats even worse, that auto data has to be wrong Why the hell would a N/A engine have a higher delivery rate than the Turbo. They use the same injectors man

If those delivery pressures were the opposite way it would make perfect sense. higher delivery pressure, regulated to both near enough the same, but the Turbos have more potential for a high fuel consumption.

It gets more and more confusing

 

fucks knows mate its the right way round as i wrote them down and just double checked it.

dont forget the turbo says 3 bar min mate

 

I give up

I said........i give up, not. you win.

So, thats that point deducted, plus that other one you didn't actually win.

AND im giving myself a point for your utter and sheer gay like qualities.

When i had my fiesta turbo, i had intermittant splutter like you describe, has it got a supechip ??? which is fitted at the bottom of the ecu ??, if so take the car out with a mate and as your driving get him to push the chip towards the ecu and wiggle it. Mine had a loose connection on the pins.

Worth a shot !!!
