Engine Coolant Temp sensor - failure symptoms?
as above...what are the symptoms for failure? Its been suggested to me that this might be causing my engine stutter.
When my car has warmed up the car can stutter on throttle. you can see from the fuel pressure gauge that pressure drops to zero. back off the throttle slightly and you can watch the pressure climb and then its ok until the next stutter!
when this happens the fuel pump also gets very noisy
thought it was fucked but i put on a new GpA badboy yest and its still the same!

If that genuinely happens then either:
1) The regs fooked.
2) Pumps fooked.
3) Pump wiring no good or the lines are restricted.
4) Blocked fuel filter.
5) Intake to pump blocked.
I dont see ANY other possibilities at all.

yes you can watch pressure slowly drop on the gauge until you back off the throttle a touch and then it builds back up.
1. i was presuming the reg was ok because the pressure remains high on the gauge well after you turn car off. would this mean the reg was ok?
2. brand spanking GpA pump
3. next option...
4/5. could it really be that? car is PERFECT until its been run for 15mins or so. can boost as much as you like. then pump gets noisy and stutter appears.
any more thoughts?

Fuel inlet, may be collapsing when the depression goes high, sometimes the inner skin may be collapsing internally, bit like an RS turbo intake hose if you follow from your old bean tin days yeah?
Why am i getting the feeling this car has NEVER had a new fuel filter here?

HI,
Agree as above check your regulator 3,bar @ idle 3.5 with vacuum
pipe off, CTS would cause the engine to run either to weak or run rich,
and then cause related problems, you need to sort the fuel pressure
out before you melt the engine as the AFR must be all over the place.

sorry stu wasnt just harping on at you 
just incase anyone else had the same prob.
cheers tho.
im off to ford for a fuel filter soon and going to change the above sensor anyway. want as many new parts on the car as possible
cheers

save your money for the sensor and spend it on stuff like new rubber fuel lines or something 
here's a thought... check the metal fuel lines under the car... i've seen them squashed where theyve ben jacked up on the fuel lines, or smashed down a bumpy road etc. it can happen.

how easy is it to change the fuel filter?
when removing it will the fuel pour all over the place or will it stop at the pump etc??
was going to give it a bash on my own and was wondering if i should run the tank dry first??

Funny that my clothes were petrol drenched and had to take 2 showers to get the petrol off me! 
lol!Looking about my books here at work, I can see that that filters on yer car are cleanable. Guess it has a screw lid, with a removable mesh.
Gesh! Just stuck my clothes in the wash yesterday on the 'get rid of the petrol smell' wash as well.

Was your fault coupled with a fuel pressure gauge showing dropping pressure at the same time as the stuttering?
No? Thought not

when i said falls to zero im not actually sure its ever gone that far. when you can see the gauge slowly lose pressure you can back off throttle and it picks up to "normal" again. not like it falls instantly to complete zero. falls gradually.

When you say its never gone "That" far.... how far has it gone?
Std is 3.5bar, idle is nearer 3, anything with boost is 3.5bar+ the boost.

long shot but could it be something in the tank thats causing the problem at the feed to the pump?
As the pump will be noisey if there is no fuel going through it
