hi just got my first rst on saturday and its broke already

when the car was workin i turned the ignition on and let the fuel pump prime up which sounded like a buzzing sound for a few secs. then the car cut out and when i turn the ignition on the pump is hissing like its just blowing air. the pump was pretty noisey when the car was runing

so does this sound like its the fuel pump thats broken?

thanks for any help im desperate to get it fixed and start using it

Is the pump running when you crank it over. Probably be worth getting someone to help you as its hard to hear in the car.

vroooom ptssssh

Can be noisey when theirs low or no petrol in it, maybe worth checing as the senders can be a bit unreliable sometimes. would also tie in with it priming longer than usual.

would neva trust a ford fuel gauge lol my s2 reads empty when theres 20quids worth init turn left it reads full lol

seems silly but as said above put some petrol in it and give it a try!

if u can hear it the pump must be working so the wires and fuel pump relay must be working !

i went to the petrol station and filled up a petrol can a put that in so there is fuel there.

i can hear the pump hissing when trying to start it but it wont start. when i made the buzzing sound it started fine.

just since the sound of the pump changed it wont start.

weve tried the fuel relay and the inj fuse and there ok.

how much is it for a new pump and where can i get one. thanks

withamxr

some erst can take more than petrol can to start after runing out

ive ran out twice ford gauges

murdoch1.7zs

it hadnt ran out of fuel

i just put more in just in case

ive had a few people look at the car and ive just orderd a fuel pump so should get that on friday.

Just keep making that buzzing sound when you go to start it and you will be fine

A fuel pump is about Ł100

SafeChav

You may of missed my post with all the replies, does the pump run when you are turning the engine over?

murdoch1.7zs

yes it does hiss when im turning the engine over.

i phoned AVA and they said that the non return valve could be away aswell but ford no longer stock this part so wot do i do if it is that aswell??

T28 RST i ordered a pump today from amber performance Ł105. ford wanted Ł189+vat

SafeChav

The car should still run if the non return valve is gone but it will be a slag to start as there is no pressure in the fuel system, bypass the relay and allow the pump to run for at least 30 secs and see if it will start then. Or alternatively leave it overnight and see if theres pressure in the system in the morning before you try and start it.

My valve was gone, it did run bit it took about 3+ minutes of solid cranking to start it.

murdoch1.7zs

i tried that on monday after it was in the garage all nite. i was trying to start it and it nearly fired up the firts time but nothin after that.

i tried it again today but the battery has died with crancking it over constantly

SafeChav

Do you know how to check for fuel pressure?

Get the battery on charge automotive batteries dont like being flattened.

akito-man

when my pump buggered it done the same,check my thread (s2 wont run,finished for now)

theres a possibility that the impellar has worn in the pump,therefore it will wizz round,but wont push fuel through,so if you know how to do the pressure check this could confirm a few things,1 as above,2 theres a blockage,3 a leak.


my guess is the pump. could be wrong tho.

murdoch1.7zs

i dont know how to check the fuel pressure

i dont want to take the battery out either this car has the most complicated cliford alarm ive ever seen

and i will need to reprograme it

SafeChav

Akito-man, these are roller cell pumps

murdoch1.7zs

yeah thats wot it sounds like its wizzing but its not getting the fuel through
u mean leaking fuel? its not leacking as when it happend it was raining and would have seen the fuel on the wet road. ive had the car up on axle stands aswell and nuthing is leaking

SafeChav

If the pump sounds different its more than likely because that valve has gone and therefore there is no pressure so its spinning freely rather than working against the pressure, as someone surther up said about the tone changing.

Try checking to see if theres fuel pressure first. Do you know how to do this?

akito-man

no impeller then???????????????????

or it could be the rollers in the pump .or the valve

bet its the pump

mine was the same and i changed the lot,injectors,leads plugs dizzy metrehead unit,fuel tank , then the pump,hey presto the pump it was!

akito-man

you sorted my wiring out for my wipers yet safeness?

SafeChav

There is every possibility the pump could be worn out, but they usually progressively wear rather than just suddenly go.

No i was looking at them wiring diagrams and screwing over them because theres so many variations between all the diagrams, im sure its only 1 wire, i'll have another look ASAP and try and give you an answer

murdoch1.7zs

how do i check the fuel pressure.

the cars done 77k so its still on the original pump and it was really noisey then just stopped being loud to just hizzing

SafeChav

A noisey pump is a sign of wear, the pump on my cabriolet was so loud you could hear it down the road when you primed it but then that valve had been gone for probably years (it was gone when i got the car) so the pumps been working far harder than it should have to.

Well, the way i prefer, is to get the air filter off, and push the flap down gently. It should have a very slight resistance, and should rise steadily and not instantly. If it springs back instantly and bounces theres no pressure. If your not sure, after you have done that, prime the pump a few times and do it again and see if it feels different.

OR you can just crack the nut on the main fuel pipe but if there is pressure fuel is going to piss out everywhere. The first option is favourable.

murdoch1.7zs

i could hear the pump runing when the car was started like when i was sitting at traffic lights

i will just wait till i get the new pump and put it on and see how it goes.

hopefully it will go

SafeChav

The airbox is simple to remove and definately worth a try, if you fit the new pump and its not that then thats Ł100+ spent and not needed, and i know that pisses me off when ive done it before.

murdoch1.7zs

well ive just fitted the new pump and it still wont start but atleast thats 1 less thing i will need to change in the next few years

it just doesnt want to fire up. the flap is moving up and down when cranking it over.

i think it may not be getting a gd spark so wot will this lead into now

SafeChav

I had a feeling that would happen, sorry to hear it

Have you checked for fuel pressure yet?? Pump working or not it could do with checking?

murdoch1.7zs

i pushed the flap down and there is a bit of resistance. ive taken the nut off the fuel filter and the fuel sprayed out then stopped, i tookn the bolt rite out and wrapped a rag round the pipe and crancked it over for a few secs and the rag was soaked in fuel.

i tried to turn it over again today. after a few atempts i took the plugs out and they were bone dry and then put new plugs in, tried again and took 1 out and was bone dry again
