Bit of an odd one,
My dse has started having a starting issue, it will start in the morning no probs even when really cold, but when I go to start it after work it takes ages, nearly flattened the battery tonite, only thing I can tell that may be different is its been parked with the nose slightly uphill, is this a known problem like fuel daring back into the tank?

Sounds like your intank fuel pump, does the situation change with more fuel in the tank.

Park it facing the other way and see if it's the same. If it starts better, suspect the in tank pump.

Or just take chocks an then never have the issue again

youmitegetian · Nov 29, 2012

Ok cheers ill replace it, anyone know if its a pain of a job or easy?

dogsbody · Nov 29, 2012

Two ways of doing it. Drop the tank or cut a hole in the floor.
CANYON did a wonderful write up with dimensions for the floor cutting.

Whichever way you do it be prepared for rusty connections and fragile pipes. I spent a hour nervously cutting my floor then replaced the pump in ten minutes.

Get your pump from a 'proper' supplier, I've seen some right rip-off prices on ebay for some un-named pumps.

I've seen some on eBay for £42, seems worth taking the risk to me, do they tend to get worse very quickly or do u think I'll have a little while to get it sorted?

Island 4x4 £41.66 O.K. + VAT + carriage

Just the first 'proper' supplier that I looked at. So, a bit more but at least there's somebody to complain to if it fails in two weeks.

As for your current one it's probably dead already. Try to keep the tank as full as possible and the weight of the fuel will help to force it down the line. Minimum 1/4 tank seems to be the concensus.

depends if you have access to a garage ramp?
me and my mechanic mate did it in just under 1hr.. tankoff /replaced pump and back on and running..hardest part was the jubilee clip on filler neck totally seized (rusty) a bit of a wiggle with some grips to break it off and hey presto..just be carefull with the fuel lines on top of pump as they corrode too,get new nuts/olives...other than that its a jack it up job on yer back or like dogsbody said-search for canyon he did a post about cutting the floor in the boot, but i didnt want to do that to me motor and was suprised how easy it was on a ramp with 2 of us..if i remember there was 4 nuts holding the tanks strap,the filler neck/breather..push fit fuel lines infront of tank/put tank on floor (i ran it low on fuel) remove old pump carefully/replace in same position/new nuts and olives and back up and on...jobs a good un

Would the car run if it wasn't working at all? Funny u say about 1/4 tank, I've run it lower in the past and it was fine but last time it struggled a bit, couldn't just be a fuse?

It'll run, the in-tank pump just gets the fuel flow started at starting. It could be a fuse or the pump partially blocked with in-tank crap.
It could just be pure chance and you've actually got failing leak-off pipes.

youmitegetian · Nov 29, 2012

Leak off pipes were replaced cus the were weeping, any idea what fuse? I can check so only if u know without searching?

RAVE out in garage, it's chuffing cold out there.
I'm in the house, it's warm in here.

I'll let you work it out

Sorry

Lol good call I'd be the same,

While you are at it check the fuel pump relay and the fuse box for signs/smells of burning. You can check if the pump runs, drop the fuel filter, bowl underneath, turn on the ignition with the engine cold, should get a get flow while the glowplug light is on. You can also jump the relay to check it.

youmitegetian · Nov 29, 2012

Jump the relay? I've swapped relays with the one for the air suspension, no change, and the air worked withe the fuel pump relay

youmitegetian · Nov 29, 2012

Ok so pump and Olives ordered from island, with a bit of luck they'll arrive by the weekend, think Ill go for the "cut the floor" method, seems like less hassle and then there's a permanent access hatch

youmitegetian · Nov 30, 2012

Oddly the rangie started fine tonite even tho it was parked uphill, maybe the pump fault is intermittent, I'll change it anyway

Bit extravagant to lash out on a pump without being sure that is the cause of your problem. It could for example be bacterial growth in the tank, a duff fuse box or a connection problem.

youmitegetian · Nov 30, 2012

Good point, I do intend to remove the fuel filter and test the pump as u suggested before replacing the pump, is there anything that I can do to be sure? Especially if it is an intermittent fault
