Non running please help!!!!!!

Hi guys,

In need of advice, we have a P38 that was running brilliantly! Lovely range rover, until recently, went out one morning wouldn't start no life at all, got cousin round to jump it which worked, took it on a jaunt and worked fine for few days, went to go out again in evening and again no life, wouldn't turn over nothing! Again cousin came out and jumped it, started straight away, went to drive following morning and nothing, no lights inside, no turn over nothing, tried bumping it again not even that worked! My friend who is mechanic came round with diagnostics and couldn't find where issue was but assumes its problem between ignition and immobiliser, having read some of the forum threads, I believe issue could be something to do with the becm and have considered get the sync mate, I just don't wanna spend £150 and it not be that, after any helpful advice out here please

Many thanks Ryan cooper

got a new battery yet?

Yeah we got new battery but hasn't made any difference, got no turn over at all, the management light hasn't come on or anything, it completely dead

Fuse box, burning smell? or signs of burning? Known issue.

No checked all fuses as having googled read that could be an issue but not the RR is fine apart from the none start, having gone trough some of the forum I think our best bet is the sync mate but if anyone could advise in this I would be very grateful cheers

Any signs of burning under relays?

If you put your location in, someone nearby maybe able to help with diagnostic etc.

Were in chippenham wiltshire, no my friend who mechanic checked for that thanks though

Petrol or diesel??
Model Year??

4.6 Petrol v8 1998

If it starts with a jump start then it's not a sync problem.

RF receiver keeping BECM awake and flattening the battery. Last time this happened it caused a losss of sync. You cannot bump start any modern car with electronic engine management with a totally flat battery and certainly not with an auto.

It did originally but on the last attempt there is nothing- we think the battery was low and that why the jump started it but on last attempt there is nothing it literally clicks no turn over at all! Would the battery dead lead to it in syncing?? We've bought new battery and it won't start from that - but no engine management light on and what I've read that mean it will need re syncing! Thanks for all advice so far though guys

Thank you datatek!!!
