having probs with the fuel pump not making the arming up sound, im told fiesta rs has bad fuse boxes has anyone else had this inconsistent sound other day lost power temporarily now car wont even start i got one of those fse upgraded ones as well

 

Have you checked the relay at all? Have you volt droppped the pump?

 

the AA bloke checked the relay the fuse box has melted a bit b4 where one of the fuses got hot apparantly the boxes in fiesta and escorts are notoriously terrible for loosening on vibration thus causing burning. the pump terminal under the seat was checked and theres power going to it so one can only assume the pumps mashed but ill know in the week as its at an auto electricians

 

Heard a lot of peoplesay Escorts and Fiesta's have issues with fuseboxes and injection relays but (*touches wood*) I've never had a problem. The injection relay is the same one that was in the car when I got it 11 years ago

 

I had the same problem with my FRST fuel pump. I traced the problem to the resister on the wiring just before the pump. I cut it off and connected the wire directly to the connector. No prblems since. Did this about 3 years ago now.


You cas see on the picture that the fuel pump wires have no longer the resister but instead are directly connected to the plug at the top.

 

thanks very much for that, i guess if i get same probs ill need to jack the car and empty the fuel tank i guess the hardest bit is getting underneath to uncrew the pump how difficult is it , is it just a matter of getting a jack and a phillips screwdriver?

 

also does those wires connect via spade connectors or did u just twist the wire

 

before you take the tank off check that you have power g'oing to the connecter at the top of the tank under your back seat. If youve got power there then you know its something to do with either the resistor or the pump its self.

I used spade connectors.

I got the car back from the auto electricians, ill write whats written on the receipt to u.

CHECK FUEL PUMP CIRCUIT TRACE FAULT TO BAD EARTH ON FUEL PUMP BLOCK CONNECTOR REPLACE TERMINALS IN BLOACK AND CLEAN TERMINALS ON PUMP /SENDER UNIT

PLEASE NOTE REWIRE DIP BEAM RELAY

i guess the block connector is the one under the back seat right?

 

Cut that little black connector out the circuit , mine failed in the middle of town for that very reason !

 

Hi, fuel pump probs agen im told theres no earth coming back from the pump after he tested the terminal under the seat, he says fiestas and escorts all have probs with pumps and that they are not good enough for the job I bought the upgraded fuel pump only a year ago.

 

Fit a new earth yourself, it is easy.

 

yeh i had them do the work fitted a new block terminal and rewired an earth cleaned up the terminals etc, seemed to do the trick but it didnt work and broke down on me AGAIN 60 miles from home an AA charged me 95 quid coz i had wrong cover and auto electrician charged me 95 for the rewiring now I have to waitr till they get the car on the ramp so they can drop the tank coz apparantly u need 2 ft of clearance from the ground to get the tank out and i cant do this on jacks, maybe the uprated was too powerful and blew a wire off who knows or maybe after only a year the pumps packed up either way i wish they had built external pumps on these i know the petrol keeps em cool but...

 

prob solved loose connectors theyve put new ones on and soldered them on shud be ok now

 

just seen this...can i ask the reason for the removal of the throttle damper from the top of the pump in the pic ??? did it have issues?? im interested as i think i have issues with mine...many thanks

 

the prob i had was whoever fitted the pump used metal crimped to hold the connectors but when mixed with petrol this causes a reaction which renders the wires useless, some ppl are saying that cuttin off the black connector and wiring directly has solved their issues, hope this helps.

 

cheeRS for that but not what im on about....on the top of the pump should be the throttle damper which looks like those sweets from years back'flying saucers' its been removed from this pic...just wondering why

 

i dsont know what the throttle damper does
