driving home from work on the motorway today and the rs just dies, so had to pull over on hard shoulder. tried to fire it up again and nothing, just kept turning over. i left it for a while and it started again. this happened three times on the motorway, any one have any ideas what it could be??

It cut out whilst still on the accelerator? or when you lifted off the pedal?

sean_rsts2

now then mate are you still having simmilar sort of problem?
yeah it cut out whilst on the gas, think my problem is just gettin worse, as where before it use to do it mainly at petrol stations if you can remember previous post!

I think i remember the posts now mate yea.... The only way mine used to do that was because of the airleak from the dumpvalve. When the engine was warm, the leak got worse as things expanded and allowing more air out.

Im guessing yours started again after it had cooled down a bit?

sean_rsts2

i dont think its an airleak, probably takes 3-4 mins to get started again if i keep it turning over. its strange and hard to explain really.

sean_rsts2

smila

iTrader: (1)

if its priming ok doubt it will be relay

sean_rsts2

My fiesta turbo was cutting out once got hot i found it was the crank sensor.

sean_rsts2

what do you tink would be the best thing for me to do?? take it to local garage or get it on the rollers for a setup?

jld0211

mine was doing this when i went to boot it put a new dizzy and rotory arm on it cured it straight away cheapest thing to try aswell

sean_rsts2

u replaced the dizzy or the dizzy cap?
ive not long changed the rotor arm and cap so i pressume that will be still working as it should.

So far you could be forking out for a new relay, new crank sensor, new dizzy.... Sean, just get it to a tuner and get it set up. They'll figure it out fairly quickly, rather than going by 'could be this or that'.

I ain't knocking peeps at all, but this issue has gone on for ages now and is getting worse. I'd get it looked at professionally mate.

Oh and is that your rs on your profile? if it is!

sean_rsts2

its just getting it to a decent tuner mate thats guna be the problem if it keeps cutting out, need to get new clutch fitted beforehand aswell as thats slipping. rolling road technician will probably abbort the run!
and yeah thats my car mate!
cheers for the help lads best get me hand in me pocket now! the joys of the rs!

I'm not sure as to why it'd be the dizzy unless it packs up mid flow... But surely if it's knackered it wouldn't work at all. Choose the cheapest option first and make your way up the list till it's sorted. Rota arms are what, £3! Clean plugs too for a
nice freebie lol Its always the small things that sort the large problems

love what you've done to your RS tho Sean. Merc grey defo the best

sean_rsts2

i have changed the plugs, leads, coil, dizzy cap, rotor arm. cant think it would be any of them that have failed. am thinking it has gotta be a fuelling issue

sm

next time it refuses to start pull the king lead off the dizzy cap and fit a spare plug and turn the car over to see if you get a good spark, if so then reconnect the king lead and pull off a plug lead and fit the plug and try again, this will let you know if your coil or dizzy are on the way out

sean_rsts2

think i may have found the problem, my garage is saying it has an intemittant fuel pump relay, so just need to source one and see if it cures!

i had problems with my escort cutting out and not starting when it was hot, turned out to be a bad earth,ran a thick wire straight from the battery to the engine block and so far so good!this was a mk4 escort with a 2l zetec tho, might be worth a shot tho.

it depends if you have a pink relay with a little yellow blob on it it should prime.
normal pink relays dont prime.

sean_rsts2

definetly found the problem now, its definetly the fuel pump relay! i have the relay with the yellow blob on it, do i have to replace it with the same one or would the just pink one work ok too??

Chopshop85

iTrader: (4)

yeah man. the only difference is one primes, one doesn't.
just the ones that dont might need and extra crank on a cold morning.
