Water in my 1996 406 pls help!

[lozz]

with the fuel pump removed can you see how much fuel/water is in tank,?
(iwouid of thought this wouid of been the 1st thing you wouid of done before anything else )

iwouidnt dismantle fuel pump you may struggle to find another one if the worst comes to the worst,
perhaps clean the filter /gauze on it

[Welly]

I wouldn't try cracking open the pump body, it'd be the point of no return. I think you should go and get a 'new' pump from a scrapper and try that. My impression is that the water has got in the pump and jammed it up (it shouldn't in theory but...) then suck out all the fluid from the tank (I'm sure the bit where the pump sits is the lowest point) then a new filter and try it again on petrol.

Ideally you should try to clear the fuel lines but you might get away with it.

Above all you MUST be extremely careful now, do not let any vapours build up inside the car, do not use ANYTHING that could generate a spark AT ALL and if you spill petrol on your clothes CHANGE THEM straight away. If you're in any doubt about anything get an experienced mechanic out; you must not proceed with any guidance given here if you yourself don't have the skill/tools needed to work safely (not saying you don't) but this job is not for amateurs.

Opened it up pics below, wan't too hard, just a motor on the inside, can i test it with a 12 volt battery, just put wires on terminals for say 5 seconds ?

how does it look to you ?

What i can say is there is the outlet from the pump seems "stuck" the motor is connected to that outlet via a thick black pipe and the unit seem somewhat sealed, so is it suppose to be like that and only allowing fluids to enter/exit if the motor is turning ? i can't blow in or suck out anything, is there a close valve or is it a sealed suction ?

The thing is Steve and Lozz, th unit is quite simple, if i can test the motor to see what it does
i might know if the pump would work before returning it, peugeot will likely charge me something like R1400 for a new pump which is ridiculous, the motor is worth R 100 i would guess.

(yes Lozz it was the first thing i did, check for fuel inside, it did have fuel inside yes, i'm not too sure how full it is suppose to be, but my guess would be it was not entirely full, however brings me back to the point that my car used to run on 1lite of petrol anyway
The only risk is if fuel comes into proximity to spark, i am aware of that, so please don't hold back your help/advise please because of that, i'm not going to do something stupid hahah... i stuffed 2 rubbish bags. partially into the opening gap to somewhat seal of the fumes in the car for now.

But i guess the next step would be to suck out the fuel, i hope i can get it all out, and then how to proceed in testing the pump....

with the fuel pump removed you shouid be able to get the fuel out of tank
now you've got access,

what makes you think the pump is at fault?

you shouid be able to see how much fuel water is in there

[406owner2]

What makes me wonder about the pump is because i never got fuel out of it when i tried to put the ign on, and i sucked hard and nothing came out, (remember my car does run on only 1 liter of fuel)

Yes i can see the petrol/water in there , it looks enough... ? .....mmm sheessh..let me think... i'll try take a photo.

Except if i've been sucking on the wrong inlet ?

[lozz]

(however brings me back to the point that my car used to run on 1lite of petrol anyway)

but the tank wouid still have its reserve

fuel pumps don't like supping up dregs from bottom of tank,

1litre plus 500ml isn't a great amount for this size of tank

Thanks Lozz, you obviously know more than i do thanks for arguing my point, i can only learn, that's why i ask dumb questions , i'm not to sure i understand what you are saying,
the car runs on liter of fuel, are you saying it had more than 1.5 liter of fuel in it somewhere else.... because like mentioned i used to only put in one liter when it ran out of fuel, i put in 1 litre and it runs after ign priming for 3 secs.

Also on which inlet do i need to suck, inside the pump, the on inlet goes straight into the (bucket)
and the other one is sealed into the motor which goes down to the pump filter at the bottom.

[lozz]

you need to get that waterd down petrol out of there mate, (or otherwise your just chasing your own tail)
then work on the pipe work suck out what you can from it then put it all back to gether and hope for the best,

you've said you heard fuel purring away so id presume its working,

once car gets to crank'ing stage the ecu might tell the the fuel pump to run longer and push and return fuel to where it shouid be going.

[406owner2]

ok let me go suck it out, i know someone mentioned a "suction" button somewhere on the fuel rail, not too syre if it applies to my car, you press on it to get the air out ?

Anyhow let me go get the fuel out and i'll report back... thanks

[lozz]

Im not here to argue mate,
and if you didn't mention you needed the car for work iwouidnt be here at all ,


what imeant was, your assuming it will run off 1 litre, but you may have had reserve too,.

idont know how big the reserve is on these but id guess around a gallon or so

That valve is for mechanics to check injector/fuel rail preasure,it is not for removing air,
best to leave that alone,

its not abutton its acap covering a valve similar to a tyre valve,

MAN i'm i full of 93 unleaded, ready for the drag race track, someone IGNITE ME !!! ....hahah...
No one told my siphoning tasted like THIS lol... the only way i could get it ALL out was to suck it into my mouth, now there are some damp spots left, going to dry out the rest with a cloth.
