hi on my escort rs turbo series 2 it starts fine when cold and will tick over all day but once the engine is warm and u switch it off it wont start again any 1 got any ideas what could it be thanks scott

 

Does it crank? If not, then it's an over-heating starter motor, probably agravated by it being crap

 

yea it turn s over but wont start i think its to do with the mixture

 

You are probably losing fuel pressure. Will it start if you crank it over for ages?

I had the same problem.

 

no ive tried turning it over for ages and nothing ive tried priming it a few times b4 starting it and still nothing have u got any ideas

 

Keep turning it over, mine used to take about 4-5 minutes to re-start when hot, very embarasing in petrol stations etc.

When you get a chance leave it over night and then check in the morning to see if its retained fuel pressure, i bet it doesn't.

I bet you also get loads of pressure when you take the petrol cap off yea?

 

hi yea there is loads of pressure when i take the petrol cap off why does it lose pressure m8 and how can i solve it its only just started doin it cheers for ur help m8

 

blocked breather on the fuel cap

 

hi where is the breather on the fuel cap is this y my car wont start

 

Right the fault i had was the one way valve in the fuel pump had gone, so when i switched off i could hear a banging noise from the petrol tank where all the pressurised fuel was being forced back in, hence the pressure when you take the cap off!

Leave the car over night, and before trying to start it, gently push the metering flap down, there should be a little resistance, and it should rise slowly.

If there is no resistance and it springs back up rappidly and bounces etc there is no fuel pressure.

If you are not sure, you can prime the car a few times after and then press the flap down to compare.

I think you will find there is no pressure

 

the flap does go up rapidly and it bounces how can i solve this problem and y is it ok when the engines cold cheers scott

 

Have you compared it to when the cars been primed and found a difference?

You will probably find its the one way valve in the fuel pump. Do you have the cold start injector wired up?

 

yea cold start is all there and working can i get a new 1 way valve and if so where from

 

Try unplugging the cold start and then starting it cold, i bet tis just as hard to start, also proving this fault.

You should be able to get the valve from Ford

 

cool ok m8 if i take the cold start out and it wont start does that defenitly mean its the one way valve

 

Yes, i was playing around with a friends series 1 yesterday and was quite amazed you can make the engine run off the cold start valve (no fuel pump relay connected)

I bet you, when you unplug it its a pig to start cold

 

cool alrite m8 il give it a go 2moro and il let u no cheers for all ur help if u ever need any help or parts give me a shout m8

 

Cheers let us know how you get on

 

i had the same problem on my series 2 changed the fuel pump relay and it hasnt done it since over 4 months now

 

thermo time switch! / faulty temp sensor!

 

the thermo time switch only operates when the engine is stone cold, and only drives the cold start injector which 99% of RS's dont use anyway.........

 

its also connected in line with the engine temp switch!

 

No its not!!!

It has nothing to do with the CTS. either of them for that matter!!

 

well i bet its a faulty temp sender !

 

Well i doubt it very much, if he has no fuel pressure its not going to be linked to the CTS is it.......

 

Air leak

Check ALL the hoses ect for holes/cracks

 

hi m8 ive just checked it and when it has been primed then left for 2 days u can feel the pressure in the metering head and the paddle comes up slowly but if u do it again theres nothing and it just goes up fast wot do u think the problem is

 

Very low fuel pressure then, should have more pressure than that

have you had that one way valve off yet for inspection?

 

no i havent where is the 1 way valve on the fuel pump

 

Screwed in the end of the pump

 

do i have to take the fuel punp out to check it

 

oh and also where can i get the 1 way valve from

 

No just take the thin fuel pipe off and thats the valve there.

Take it out and see if u can blow through it

 

ok and if i can its that if not wot else could it be oh and also where can i get the 1 way valve from

 

Valve u can get from Ford

If not try the fuel pressure regulator.

 

hi i took the cold start valve out and it started fine when cold but still wotn start when its hot aslo it sounds stupid where is the fuel pump to

 

Fuel pump is under the rear of the car, can be seen easily just follow the pipes

 

ok cheers do they ussualy start when cold with out the cold start valve

 

99% of cars fitted with Bosch K/KE Jetronic start a damn sight better without the cold start valve

 

hi ive just ordered a new one way valve but i have just noticed that when i rev my car the top boost hose is sucking in or collapsing wot could cause this cheers
