Ive got a mk5 escort sport 1.6 efi,the main engine loom has been unplugged from main harness but if i turn the key so ignition is on the fuel pump works surely this shouldnt happen or should it?????

 

Yes, this is fed from the PCM, so is correct.
tabetha

 

Is the pump meant to stay on permanent?????

 

you still not got the car running mate ?? let me no if you ever want to sell it

 

No, it should prime then stop, sounds like the relay has #### its self or someone has bypassed it

 

Nah still not got it runnin yet got to wait till i get sum cash together to buy gotech management for it and see if that works

 

MK5RST, I will have to have a good look at it 2 moz if its not pissin down of course British weather is boll** Thought it was meant to prime then stop. thanx mate.

 

its not a problem mate it will of been bypassed, another bas escort fuse box!! just find the switch wire from the ecu at fuse box and put a new relay on it if you want it right. 10 minute job mate. thin brown wire i think and fuel pump wire is thick black red?

 

just re read whys it not running? no spark/injection? will prob be fuse box again! do you have a power probe?

 

NEEDFORSPEED, Yes ive got a power probe the reason ive asked the question in the first place was ive taken the whole engine loom harness out including ecu but pump still runs constantly i was wondering if the pump relay may be picking an earth up from sumwere else as there is an earth wire that goes to the main harness that isnt earthed coz its not plugged in. Ive also tried a continuety test from the main engine harness plug back to the fusebox but cant seem to find any of the wires that are meant to go to pump relay from harness

 

na ive never had one thats picked up an earth 90% sure it will of been jimmyed.try and find the fuel pump relay and see if the switch wire is there it may just be that the fuse box had lost live to relay rather than the trigger small brown relay i think in the middle?

 

Ok nice one mate may have a look 2 moz weather permiting

 

ive just bought an rs 2000 so if you get stuck for the wire il have a quick look at mine and find it for you. im sure youl be fine tho

 

I will let u know mate thanx
