Title: Hesitation when under 20l in the tank? and others
Post by: o-meg-a on 03 May 2011, 07:40:43
Odd as it may seem,
I have started to notice that when i let the car get to around 20l of fuel left in it (i always fill to brim),
I start to get periodic hesitation.

By hesitation, i mean that sometimes i put my foot down, and i get bugger all back....instead of the usual whoosh from the chipped diesel that i am used to.

Eventually it clears after a couple of seconds, or mins and goes back to normal.

On top of this problem...I also have a starting issue when i let it get to 20l or below.
Usually from hot, but sometimes from cold, when showing under 20l, instead of starting on the button like it normally does with a full tank, it will spin over very fast and i may have to turn it over for 10 seconds or so, pumping the throttle to get it to kick in.

hasnt failed to start yet, but i fear one day it might.
Is this the lift pump?
Or is there something more sinister at play here

Well there is my first port of call then.
I'll follow the guide and give it look over.

Also going to fit new fuel filter and fill it with diesel magic.

would this somehow be giving me less MPG too, as i have been slightly disappointed with my chipped figures.

There has been some here on oof that have removed the chip as is used more fuel.
The Boy would be the best person to ask about the different chips as theres a choice of three :y

Well i say disappointed. I still got 42mpg on a long run. BUT, around town its more like 29.
I'd rather keep it up towards 40 to be honest lol
