Freelander 1 Nuisance starting?

Andy J-R · Dec 6, 2015

My 2004 TD4 Freelander is getting cantankerous, at a time and a place of its own choosing it will turn over but not start, using the remote (key out of ignition), lock and unlock a couple of times and then it strikes up without a murmur.
Ideas?

First welcome to Landyzone feel free to introduce yourself. As to your issue of not starting. Start with the basics first with fuel line to the filter and then to the engine. Make sure there are no leaks. When did you have a last service in relation to the fuel filters being changed. Ignition doesn't seem to be a problem as you are cranking the engine so next do you have garage that can do diagnostic test to see any issue with the immobiliser interfering.

The old bus is indeed due for a service, booked in for the week before Christmas, the immobiliser interference resonates with my own thoughts. Many thanks for taking the time to reply, I'll try and track down a local garage with the right diagnostics.

if there is plenty cranking amps, the two things common i would be checking is crank shaft sensor for one and then secondly i would be checking for excessive injector leak back rate.

Thanks to all, after yesterday's efforts the old lady just refused to start this morning, and when she finally started to run the engine management warning light lit up and after a few hundred yards the engine died only to restart first try, no warning lights, and then run without a murmur for the rest of the trip. Booked in with my friendly neighbourhood auto-repiar shop ( with computer diagnostics) on Thursday. I'll post the outcome

Buy you own diagnostics (off me!

do you live very close to a police or ambulance or fire brigade place as and when they transmit over their radios it can mess the computer up.

Are all your earth contacts clean?
Random but ive experienced this with a fiesta many moons ago. Earth on that was loose and the vibration used to cut it out, not start, rough idle.
A wire brush and a spanner later, sorted, never had it again.
I had started looking into ecu problems which could of been costly, was worth properly checking.

Thanks for the ideas, but probably not electrical - everything lights up and the engine turns over freely but doesn't fire up. After a couple (sometimes several) of resets with the key fob it will start and run for a few minutes then the engine management warning light comes on - if I persist in carrying on after a while the motor dies, however if I stop, switch off and then restart (fires up first prod) everything is then fine for the remainder of the journey.
I'm fairly sure its a fuel problem, either the pump is faulty or given the key fob response a fault on the immobiliser. Providing it'll start and get me there the old lady is booked into the workshop tomorrow for some professional help.

Thanks to all for your ideas and help, a new fuel pump, common rail pressure sensor and some electronic wizardry with the immobiliser seems to have resolved the old girls cantankerous ways for now. Fingers crossed

February 2016 - after spending a lot of time and money on the old girl she ran sweetly for a week and the started the whole performance again. Six weeks later with the attentions of Land Rover Services in Hull, Replacement fuel pump, injectors, filters, sensors etc.etc. it ran for about 50 miles and then refused (refuses) to start. Engine turns over and if it does start runs well - but mostly will not start.
Seriously considering the sledge hammer option - ideas?

ouch, I hope you didn't pay for all that !
There must have been a fault code stored if it brought the engine management light on.

Andy J-R · Feb 13, 2016

Yes, it was the common rail pressure sensor - replaced the sensor and the pump, stopped the light coming on but the starting problem persists - as to did I pay, not yet but I've got the bill - huge, reaching the point where the car is no longer worth it :-(

Did the garage check your cam and crank sensors?

You mention replacing two fuel pumps - have they replaced the LP and HP pump?

Next step would be to check you have 5v reference voltage on each sensor. If there's a problem here, it could be the ECU.

the common rail pressure sensor harness is another weakness and most change it with a new sensor.
