fuel cut

[RA Dunk]

came off a roundabout tonight floored it  about 5-6 k and engine cut out  for a split second ,

just fitted a uprated fuel pump and FPR on friday  , any ideas

[philip_wilson]

Spooky mine did the same tonight in the B.O.D booted it in
second off the roundabout and it died for a bit then took off like a rocket
again put it down to lack off fuel due to travelling sideways.

[RA Dunk]

yea funny enough mine was in second as well , tank was inbetween 1/4 and 1/2 full ,  any ideas?

If you fitted the new pump with the supplied filter it's probably fuel starvation because of the small filter.

Remove the pump and re-fit the std filter bag to the new pump

Acid - yours is a UK MY95 car right? Have you got a boost gauge on it? what is your peak boost?

Did you fit the OE fuel filter onto the new pump or the smaller new one? How much fuel was in the tank?

I thought it might also be due to having the full decat on it and you were getting a boost spike, but from what you describe (ie roundabout) sound like fuel starvation.

edited due to me thiking the wrong thing[:$]

[RA Dunk]

err i dont have it anymore , guy who fitted didnt give me the old one back [:S]

[philip_wilson]

Yip we need to stop booting it off roundabouts lol. I'm not
sure but mines felt like it was about to run out of fuel, but was fine the rest
of the way home still got about ¼ tank left from a full tank this morning.

ps - if you haven't got a boost gauge.....................................GET ONE!

mines a my95 , yes i have a boost guage (but its sitting next to me

here lol) i got sent the wrong pod for it so it never got fitted

yea mines felt like it was about to run out of fuel as well , im a fussy little c**t when it comes to the car i like it to run perfect

[*-)] Are you supposed to fit old bag onto new pump like? surley new bag would be cleaner. There was a bit of a difference in size though.

[philip_wilson]

Ac!d has it happened before? I had the same thing about a
week or two ago but it was on a straight, very slight power cut then fine again
not as bad as tonight, it was like full power then nothing then fine, saying
that I did stop to see if the engine was still there.

[RA Dunk]

no it hasnt happened before m8 , so that makes me believe it s either the pump FPR or maybe something to do with the full decat i just gave it?

[thefastone]

I'm sure that there was somthing about  going round corners (Left or right I cant remember) with the fuel being lowish... and the engine spluttering, Mebbe thats yer problem....

Just a thought like...  [:$]

[RA Dunk]

dont think the fuel was that low TBH between 1/4 and 1/2 a tank , its never happened before

Think that might be it in my case, both times it happened to

me I was heading for the petrol station. but still had 1/4 tank left

[thefastone]

Yeah the only reason I thought about that Was that it sounds like a fairly localised occurance... ie both going round the same corners etc...

[RA Dunk]

hmmm im going offshore tomorrow im  just gonna take it easy on the way

through to dyce and the same when i get home then get somebody to check

it out when im home again probs simon at japperformance

[euan_r]

thought 4wd models had some sort of method for siphoning between left and right sections of tank involving fuel return pressure. or maybe thats just leggy

[gogsie]

Had this at Knockhill coming out of the hairpin. I have a newage and fuel starvation is known to happen even at half tank. TSL now sell an anti surge tank kit for new age - £270 IIRC. 

[RA Dunk]

yea but this hasnt happened to this car before (and i like roundabouts ALOT [])  so im thinking the car isnt liking some of the things ive just done to it []

[philip_wilson]

As long as it doesn’t go bang  we will be okay.

[gogsie]

Since I fitted my H&S Exhaust I get a sharp drop off in power for a split second. When on RR on saturday Simon pointed out that the boost was spiking due to the free flowing exhaust allowing turbo to spool up real quick.

yea but i dont want it to go bang lol

gonna get it checked out anyway next time im home again , ill just take it easy till then [:|]

The boost spike issue is (obviously) worse in winter with the more "dense" charge. Gogsie never got his restrictor opened out by me as he said he was getting Andy to map it soon so I felt it would be OK in the Summer months and the wee spike  would give a better "kick" to the mid-range grunt of the car for the time being. Look like I might have to open it a little!

Acid - the most plausible reason why your getting the problem now is that you are using the new filter bag that is smaller and sits a little higher and more horizontal than the OE one. I have also found that some of them face COMPLETELY THE OPPOSITE DIRECTION to the OE one.
