about 6 weeks ago my s2 broke down and wouldnt start again so i called the aa who towed me back i new it was a fuel problem and he confirmed this problem is dont no what it could be the fuel pump is fairly new b4 it cut out it was popping and banging then jst died would the fuel relay do thisor do they just go straight away

 

tbh it sounds like it run out of fuel..lol. is your guage accurate?
other than that live the pump from the battery and see if it runs if it does then the pump is ok and its either your wiring or a relay, if still it dont work its the pump.

 

no its not out of fuel and the fuel pump is not priming

 

if the fuel pump aint priming then its most likley your fuel pump relay
its under the drivers foot pedals and its a pink relay!

they are prone to burning out !
check it and u'll tell if its been hot or burnt!

 

checked it they is a bit of a green mark round 1 connection thats it

 

CHECK THE INJECTION FUSE THEN IF NOT I WOULD REPLACE THE FEUL PUMP RELAY JUST IN CASE
TRIAL AND ERROR I'M AFFRAID !

 

I'll agree with you they are prone to burning out:



I could smell that fucker, pulled over just intime i think everything was RED hot

You can check if your pump is working by bridging on the relay plug, with the relay removed and the ignition on, the Black and Black/Red wire, if it doesnt run, first check the fuse, and if thats ok i'd say its the pump, or connections on the pump.

 

all sorted its the relay thanks where is the injection fuse tho

 

On yours? Series 2 yeah? Should be fuse number 6, 25A i believe

 

ok is that the fuel enrichment fuse as i dont no where that is neither cant c anything with heated seats on fuse box lid yes it is a s2 thanks alot 4 the help mate

 

Its all the same thing, main fused & over voltage protected supply for the KE Jetronic ECU. Its number 6 im sure, the fuses should be numbered on either the lid, or look closely in the fusebox and you should see little numbers in it.

 

found it the fuse is melted but it isnt blown best change it anyway

 

Was it number 6? Fuse melted, hmmmm, doesnt sound good, the fuel pump wiring on these cars leave a lot to be desired!

 

everything seems ok tho bridged the relay 4 now can hear the pump cant start it tho as the bat is nearly flat so i will try it at the weekend since i have had the car it has started crap when cold thats why i was wondering bout fuel enrichment fuse

 

I see, try disconnecting the cold start valve, they make matters worse more often than not, and its pretty common for an MFI RS to missfire slighty when first started, soon clears up though.
