someone out there must know ? i have just brought a rs turbo s2 1.6 that has been dropped into a ford escort 1.4 shell nice hey !! but there is a small prob it is hopping and popping not all the time but fuel pump sounds loud makes louder noise when about to stall have changed ecu sparks dizz and rotor arm not leads also going to change fuel pump and fuel relay ( can someone tell me where that is also ) sorry guys but not a machanic !! this is so upsetting i only had the car 3 weeks and aint used it it drives well but when going into boost the thing pops and farts about the goes back as if nothing has happend but the fuel pump is making a lot of funny noises well any help would be usefull cheers guys or girls !!

 

fuel pump is under the car near the tank,the fuel relay should be just above the pedals(pink in colour)!



when they put it in DID they change the fuel tank to the rs tank?

 

could be so much something as simple as plugs really you need to get it to a tuner for a good proper look over

 

Did they fit an rs turbo fuel tank or keep the standard 1.4? if its only the 1.4 it wont have a swirl pot which will more than likely be causing fuel starvation hence the spluttering etc. If its a rst fuel tank it may be the pump on its way out.

 

no have not yet put fuel pump on car no still old petrol tank

 

no its the same tank a 1.4

 

get an rst fuel tank fitted. more than likely your problem

 

cheers will give it a go to see what happens hope it works cheers dude

 

also the car can start up on one click and then it can take up to 7 pumps on the gas pedel to start the thing up ?? ecu has been replaced but i noticed there is a black box near the ecu ?? whats that !!!!!!!!!

the ecu that controls the fueling

 

Doubt it's the fuel tank unless you drive about with 2 quids worth of fuel in it .

 

after listening to the car on warm up on cold start it backfires alittle the on warm up it gets worse ? what could this be ( should i try valve clearance ) valve stem seals ? as somke on start up aswell or head gasket ?

 

There is no valve clearences they have hydraulic cam followers.

If you've got a 1.4 on it still then change this thats not doing you any favours, i'd love to know how exactly the fuel pump is connected to the tank if it is like u say the original 1.4 tank, should be highly amusing

Theres no way the fuel pump is going to be able to suck enough fuel up from the 1.4 outlet, and would probably also explain why the pump is so noisy......
