TD6 Service / Now wont START

**33chinacars** · 1st August 2012, 09:45 PM

Hi Steve

Hows things on that side of the world.

Yes flattened battery while trying to start car. TWICE
So as you say hope my F & C problem sorts itself out.

Also noticed a couple of other problems on a longer drive today. Car settled to Hwy hite at speeds above 100 kmh. But then went back to Std hite without going bellow 70 kmh. Seems to have corrected itself on the way home.

The other thing is it is now harder to start especially if it sits for any time. Its as if fuel pump is now loosing its prime. Or an air lock ?? Had to cycle ignition twice ( about 20 seconds each time ) before it woul start. Before servicing even after having not been driven for a week or more it would only that a few seconds ( until dash lights went out) before it would start.

And I love my IIDTool

As do others that have them.

Has the inline fuel pump ever been replaced? Mine did this, then a few weeks later (its a daily driver) it started loosing power under acceleration.

its only a thought, may not be your issue, I don't know other peoples mileages, mine was done at 120k, and again at 210k.

Garry, you either have a leak (fuel running back allowing air into the system somewhere) or need to replace the inline.

Mine went @ 140k, have a mate who lives at Tweed, his went this week @ 92k, however both of ours just failed, came out to start it and no go. If the inline is the problem you should have a fault about low side fuel pressure in the engine ECU (no dash lights). The ECU actually stops the engine from starting if the pressure is below its preset to prevent damage to the common rail pump.

If it seems to get worse the longer it sits I would be looking for a leak. Have the all the clamps around the filter been replaced with screw up ones? Can you move any of the fuel hoses (engine bay and all the joins around the inline)? Filter on properly?

Yep, replaced clamps on filter. But will be rechecking all again & inline pump which hasn't been touched.

041260 - P1180 Low side fuel pressure sensor. Plausability ( Fuel filter) Pre-delivery below starting required

Had this awhile ago. Cleared fault and didn't come back. So didn't worry about it too much.

So more likely pump. With everything O'k till I played with filter

Thanks Harlie

That would explain why it wouldn't start after filter change

Mine is definately on borrowed time. If I let the tank run below 1/4 it is pot luck whether it will start again or not...

So far, when it doesn't, leaving it for a few minutes, or adding a jerry can of fuel has done the trick. I suppose I should order one before the enevitable happens and I have to bring it home again on a tilt tray...

Sorry guys, dumb question, which one is the inline pump and which one is the filter? New to these motors but handy with the spanners! Do these td6 have an in tank pump?

There's three low pressure intank pumps, then there's the high pressure inline pump located next to the tank at the back of the car, then there's the super high pressure mechanical pump driven by the engine. The filter is a largish canister thing with two hoses going in the top, clamped to the right of the engine if your standing infront of the car looking at the engine with the bonnet open.

Fuel filter picture pinched from FFRR.com:

If you have a copy of RAVE then its al shown from about page 152 onwards. Or check out an online version of RAVE here: http://www.scribd.com/doc/44424637/W...22-Range-Rover from page 150: http://www.scribd.com/doc/44424637/W...Rover#page=150

The mechanical pump supposedly will be damaged if its not fed enough fuel, so the cars computer ecu either wont let the car start, or rev limits the engine based on fuel pressure in the scenario there isnt enough fuel pressure.

When I was looking at TD6 L322's, most sellers pointed out the inline pump had recently been replaced as it seems to be a common failure point which if anything should be put on the 100k service interval.
