This has happened a few times now and starting to get a bit more frequant.

It'll pop with the revs dropping and stall. If you keep blipping the throttle to try keep it running it will pop.
Also then when you try starting it back up it will turn over, sometimes starting and then sometimes not evan a click. Leve it for a bit and will turn over.

Any ideas what it could be?

 

when does it start to pop? when u first start or when u've been booting about?? on boost??

 

Once I've been driving for a bit. Does it anywhere after 2500rpm on or off boost. Going over bumps seem to play a majour part in it aswell.

 

Air leak?

 

do u have a dump valve?

 

yeah I've got a dump valve on it.

 

if it was an air leak surley it would just strugle to ideal, i'm inclined to say it could be over fueling

 

Just notice a earthing strap from the body conneted to nothing else near a box just b4 the fuel filter. What should it B connected to and could this b causing the prob?

 

Yeah I thought it was over fueling but would of thought it would cause it not to start up straight away after cutting out

 

mate its your fuel ecu playing about.

 

I'd personally say its a loose connection somewhere, when you say sometimes theres not even a click when trying to re-start? Can you expand a little more on that? Are the dash lights always on?

 

Yeah the dash lights will always come on. The engine will turn over a couple of times then when you turn the key about a third time it wont do any thing cept for the lights on the dash comeing on.

 

even if this isnt the problem still take it off. no need for them unless ur running rally car boost!

 

I've connected that loose earth wire that I found to the engine and it seems to be ok now. Haven't took it out for a long drive yet tho.

Cheers for the help tho.

 

I had simular on mine, it was all down to bad earth, you can still buy new leads from ford.

mate this happened to my S2.
after spending money on a fuel pump and relay, spark plugs and leads new boost hose.

it turned out to be:

the Distributer body.

unscrew the two screws put a 2nd hand one or newy one on and bet you have no probs.

 

Ok thanks for that. Mite aswell give that ago to.

 

Also check your metering head flap isnt getting stuck causing it to over/under fuel

 

had the same sympthoms with my rst before, turned out to be a loose connection, the + connection of the battery.
perhaps yours is corroded or a bit loose?

 

K cheers. will give it a good look over at the wk end.
