Strange One.

Travelled back from Birmingham with no signs of any problems on the way up but on the way back as I came to a stop at a roundabout the car cut out.

It started again and a few miles down the road I pulled over and turned the key off and started the car again, this time it started but idled like it was missing and no response from the throttle.

After 2 mins of trying the car came back to life and lasted all the way home without a problem. This morning started it up and it turned over but failed to start, after a few turns it kicked into life and again didnt feel right but after 3 mins it idled and drove like normal.

I'm thinking its a fuel problem myself and checked if I could hear the pump going and it was, could the fuel filter cause this problem or perhapse the pump?

Dont have a reader to look for a code.

Any help!

Regards

Sounds similar to my problem I had with my 05 TD4. Have a look at the plug on the end of the high pressure fuel rail sensor. My car started to play up when the previous owner had it checked last October by LR. They couldnt find a fault so he sold it. I bought it from a garage with no knowledge of the problem - have a look at the link below.

good luck


 
could it be the filter that is on the end of the intank fuel pump mine was absolutly chocked and the pump did not last long after that the filter can be pulled of and cleaned

I might have a copy of that bulletin on my floor somewhere if it comes to it. I may even find it if i tidied up, but the chances are slim
 
Cut out again and just turned over and over, waited for it to cool down and it started fine. Runs and starts great when cold but when its had a good run and hot it fails to start.

Also noticed the Synergy2 is not working I turned it off and no differance whats so ever to cars performance so Im now wondering if it could be the MAF or the actual Synergy2 at fault?

Any idea?

May put in the old Bosch MAF and see if that helps.
 
Just changed the MAF from the Pierburgh ro the old Bosch and it now flies and back to normal.

Will next weekend do a long run and see how if it cuts out then but it didnt after a test run just now and engine was hot.

Hope its fixed but it does look like the Pierburgh MAF as gone tits up.

Regards
 
Seems odd. Even with a dud Maf the engine should still run on the ecu's default strategy.
Time will tell, maybe engine heat is affecting a connection.

If it does happen again, perhaps it's something you have disturbed in the process. Swop the Maf back over to confirm. Could even still be something up with the synergy or synergy wiring? You said yourself you couldn't feel any difference when you turned it off. Disconnect the synergy and revert to the original connections if it happens again at least you'll know its not the synergy. If the unit did turn out to be faulty I'm sure Ron would repair it.
 
Changed the MAF from the Pierburg to the Bosch and it started and ran well, power was back but today wife called me and said car had cut out again, so out I go.

Turned off the Synergy and turned the key and after a few seconds it fired and started up but how long its going to run for I dont know.

Now I know its not the MAF but could be the Synergy itself or something else.

What I dont know.

Can someone post up part numbers for the sensors that go tits up and links to cheap sellers cos I sont have a clue what Im looking for and Im not paying a garage to fix a simple fault, that if it is simple to fix.

Regards
 
Will add to the below point. Misses was low on diesel and called me from work saying it took an age to start but put fuel in the car on the way home.

But the car as above cut out and failed to start until I turned off the Synergy.

Could be the filter perhapse?

Just called my local LR service dealer and explained my faults and findings and he said that the most common fault is the low pressure fuel pump.

I said when I turn on the ignition I can hear the pump (rear arch) and he said thats sounds faulty as the pump should be quiet.

Any thoughts.

PS,

When I went out to recover my misses (above) I turned off the Synergy and after a few turns the car fired. Could it be a sensor, harness or pump even the Synergy at fault?
 
process of elimination is the best way to go........ if your back on the Bosch maf start by disconnecting the synergy (as opposed to turning it off) reconnect the two original connectors and run it in standard form for a while to see if it reoccurs.
 
cam position sensor can sometimes cause hot starting problems.

LR dealer is talking b*ll*cks. Never found a fuel pump yet that's completely silent, they should just kind of hum like they've forgotten the words.
 
Well it's humming to my ears, also called rover Ron and he also said it very well be the pump.

He said because the tank was empty of fuel there could be a loss of pressure and the pump has to work harder and if it is faulty it may be the cause.

Strange though how I turned off the Synergy and it started, I'm thinking could it be the fuel rail sensor, will take the lid off and clean the plug and see if that helps.

Regards.
