Car was sat on the flat part of my drive last week when it ran out of petrol.Tipped approx 4 litres in and it started fine. I then moved it onto the sloping part of the drive and parked it there for several days,with the front facing up the drive.
Tried to start it again but it didnt want to know.Tipped another 5 litres in the tank,still nothing.
Tried again today,and as a last resort pushed the pedal to the floor and it burst into life.Ran nicely at almmost full throttle,but rough as hell on a light throttle.Cut out after perhaps a minute of running like this and wont start again no matter what I try.
I took the petrol feed pipe off and turned it over,lots of petrol spurting out.
Plugged O**** in, no codes showing.
All ideas welcome.Tia.
-
did you take spark plugs out to check them?
-
Not yet,although I know they are in good condition,but havent actually checked for a spark yet.Thing is it did start briefly,so if its a HT problem,its intermittent to some degree. :-\

It's Omega code for "break me, break me, break me!!" ;D :P :-X

know something about it
mine had this code :o :o

You break yours and I,ll break mine. :P ;D
Its a bit of a strange problem though.I have a feeling its connected to running out of petrol,but it has me stumped at the moment. :(

Almost sounds like you've got an airlock somewhere... :-\
Have you still got it packed on the slope? I think I'd want to try it on level ground or, preferable, pointing downhill, just to rule it out.

If theres an airlock its in the injector rail,if thats possible ? :-\
Ive jacked it up at the back (trolley jack under the towbar) so its now sitting almost level.It has always ran as sweet as a nut since I did all the work on it,until now. :(
-
I wonder if it's worth trying the pressure relief valve on the injector rail. I think you need to remove the plenum to get to it though. :-\
-
when you done this work??
did you take inlet manifold off?
take rubber pipes off and check if you dont have anything stuck in throttle body
-
Work was done months ago.Car has run fine until it ran out of fuel last week. Symptoms seem strange though tbh.Dont fit the usual patteen ime.Particularily as no codes thrown up. :-\
-
Just tried pedal trick.push brake and throttle pedals to the floor and then switched on ignition.pic of car with spanner through it flashes constantly. Immobiliser/ key chip problem ? :-\

I think that just means there are no codes stored. I'd need to check the guide to be 100% though...
...just checked, I was right! :y
-
Why wont the facker run then ? >:( :'(
-
Ok, assuming it is linked to running out of fuel, it's either going to be an air lock or crap in the fuel lines. Really can't see it being anything else. :-\
As you say it seemed to be pumping fuel ok when you remove the fuel feed pipe, that would suggest the the fuel filter isn't blocked. So I would definately try the pressure relief valve next.
-
Will have alook tomorrow,weather and everything else permitting. :y
-
If it's an estate, put another two cans in it and try again :y
One can isn't always enough :-X
-

Agreed, stick at least another 10 litres in and try again...
Any chance you could have tipped diesel in by mistake?

Or veg oil, ya blind old bugger!! ;D
-
Definitely no diesel or veggie oil. ::) :P
Will try more petrol,but its spurting out the supply hose like a fountain which suggests to me its getting plenty up to the fuel rail.May be wrong though. :-\

no codes.. either fuel or ignition problem..
I would be suspicious of pump not working properly - works and randomly cuts- may be.. try swap..
and check sparks :-\ may be some water on/in ignition components..
-
Might have flooded it then :-\
Pull the two small purple relays in engine bay fuse box and turn it over several times. Pop another 10 litres or so into it, refit relays and try again :y
Failing that the pump might be on its way out, but try above before condemning it :y
-
Thanks chaps,I will try these ideas tomorrow. :y
Can swap a known good pump from my own car.Will be p1ssed off if it needs a pump as Ive sent two cars to the scrappy in the last year with pumps still in the tank as no-one ever wants them. ::)
-
Think I've got a spare pump somewhere mate. :y
But would a partially blocked fuel filter (caused by dragging up crap from the bottom of the tank) produce similar symptoms to a failing pump?
I wonder if a new fuel filter might be worth a try... :-\
-
Its on the list of possibilities. :y......and if I need a pump (and a dispack for my own car) I will give you a shout. :y
-
Why don't you take the return line off the fuel rail and run it into a can with a length of hose? If fuel issues from there at a reasonable rate you know it's been right round the fuel rail and also that the fuel rail is probably pressurised, since the FPR has to open for any return flow to exist.
If you've got fuel there it's something else, I reckon. V6s tend to fire up first turn of the key even from dry in my experience.
-
Mine too Kevin,thats why Im stumped.Perfectly logical regarding the return line btw.I will do that. :y
Having said that,I have heard several estate owners say that they behave differently to saloons when they have run out.
-
I hope injector(s) not pissing :-\

Mine gets quite sensitive to both pitch and roll once down to the last couple of gallons :-\ had it cut out before now without the low fuel light on and a range of 45 miles on the MID :-[
The pump lives towards the rear right hand corner of the tank so any combination of slope away from that increases the chances of cutting out quite significantly. :-\
Had a 2.0 Efi Granada that refused to fire when the pump got weak. It used to do 400 miles every weekend, and nothing during the week. Went to drive it on a friday evening and it cranked readily enough, with fuel reaching the rail. It was only when compared with an identical car that the significant difference in fuel rail pressure became apparant. :-\
Fwiw, my money is still on the fuel level, with the filter and pump following up. Rank outsider would be the crank sensor :y
-
Im about to remove the filter and take a look at that.I forgot to change it with the other filters,so it would be an idea to change it anyway.May also test the pump. Will get another filter in the next day or so and chuck some more petrol in at the same time. :y
-
New filter certainly won't hurt :y
-
The good news is that the pump works when power is supplied directly to it. The bad news is I was removing the filter,using screwdrivers on the "quick release" clips and broke the fitting off the end of the fuel pipe.Not the short pipe which goes back to the tank.The long one which runs to the front of the car. :'( :'(

Ooops ::)
1. Cut the pipe as close to the busted clip as poss.
2. Take the removed piece to the nearest marine chandlery/boat yard, and buy 6" of 7480 fuel hose of a suitable diameter and 4 stainless steel jubilee clips, again of suitable size.
3. Attach one end of the hose to the cut pipe, securing with 2 jubilee clips.
4. Attach tother end to the fuel filter, again securing with 2 jubilee clips.
5. Whilst waiting for kettle to boil/pint to settle (delete as required), turn on ignition and check for leaks.
Job jobbed :y
-
Sounds like a possible way forward Al,thanks. :y
-
May have some of that spec hose at work.Will make enquiries tomorrow. ;)
-
Albs, is the car facing down the slope as per the pics in the for sale thread :-\ if it is I would pop at least another 10 litres of fuel in before trying anything else :y I've learnt this the hard way :-X
These estates will run on the road all the way down to a flashing light with no problems at all, but as soon as you stop on anything vaguely resembling a slope it will cut out before you can say " I really must put some fuel in this"
Putting a couple more cans of fuel in is easier than changing half the fuel system only to find it needs more fuel :y
-
Its facing up the slope Al.I tipped another 7 litres of fuel in the tank as you advised and....................................it fired up and ran as sweet as ever. :-[ ::) ;D
Thanks for the advice btw,I would never have believed a car would need so much juice to get ut running again if you hadnt been so insistent. :y

I told ya.. dont park at 90 degrees hills ;D

Good result mate. i suppose if yoiu had the nose up over a few days then the fuel would slowly drain all the way back to the tank? :-\ is this where its a good idea to prime the fuel pump before firing up to circulate the fuel again? :-\ i dont know just guessing.
re your fuel filter TA, that mod with the jubilee clips..... is this just for if you break yours like albsheimers did? or is it ok to change anyway? i loathe those really fiddly-special tool needed-PITA quick release clips and would much rather have a ''free in 5 seconds'' jubilee set up :y

The fuel pump runs for a few seconds every time you turn the ignition on to ensure it's primed.*
* - On DBW Omegas. I believe some earlier ones don't prime

I discovered that mine sometimes does, but cant understand on what parameter decides :-\
ps: anyway I have added an extra checkvalve so no probs ;D

Often it'll fire a shot of fuel through the injectors at the same time. I think it then starts a timer to inhibit priming for a while, so if you turn on and off a few times, you don't flood the engine.

Albs.. I am leathered and reading your post. I have totally forgotten your pipe mate until now :( I am so sorry.
I will go down tomorrow and remove it then post it down to you
Just to add c ant think of on time I have had to change a fuel pump in an Omega so not a common thinkg mate x
Yours always
Daz :-*
