In the battery issue the battery is less than 3 months old costing £90 so I can’t seeing it being faulty it’s an exide one too yes had mechanic come out and he said I’m getting fuel at injectors so think I’m going take battery off and charge it and replace glow plugs and go from there ...I’m still thinking it’s a becm problem myself only thing in the back of my mind I read up on here soneone saying if I’ve lost sync between the becm to ecu I would get no check engine light on the dash at all but check light comes on on key position 2 then goes out once it’s cranking ....as I say it’s always been hard starting the past 3 weeks then now it’s cranking that’s it not firing so agen if it were the becm was that a sign of it failing the fact it was hard start at times etc??..

It's not a BECM issue if you have fuel to the injectors.

The Check Engine light is only a sign of sync (or lack thereof) on GEMS Petrol vehicles - as the GEMS ECU will illuminate the CEL if it is in receipt of a valid code and will allow starting. The BECM monitors that line and will then allow starting if it sees the signal back from the ECU.

On the Bosch ECU'd vehicles - the Diesels, and the Thor Petrol, they don't acknowledge the receipt of a code, and as such the immobilisation code/starting strategy in the BECM is different. On a Diesel, or Thor Petrol, the BECM will always allow cranking etc (which it will inhibit if no CEL acknowledgement on GEMS) and the actual allowing/disallowing of actually firing the engine up is inhibited by the engine ECU. In the case of the Thor, I think it inhibits the fuel injectors and sparks. In the case of the Diesel, as you have - the ECU inhibits the FIP from sending fuel to the injectors.

One of the good indicators of sync issues on a Diesel is fuel to the injectors. No fuel = no sync (or another fuel delivery problem such as air in the lines, or bad in tank pump for example). Fuel to the injectors means there is fuel getting THROUGH the FIP, so the ECU can't be immobilised and it's trying to start.

If your battery is in good nick, then I'd start with the glow plugs. I had one owner I repaired a BECM for last year keep asking me if the issue was the BECM after I'd looked at it - to the point I took it back, and re-tested it etc. It was finally found that his glow plug timer/relay fuse had blown, and he had 2 dead glow plugs. After replacing the plugs and new strip fuse, it started and ran fine.
 
Really appreciate that it’s veru useful information regarding the becm well my battery was completely flat so that’s on charge I’ve ordered new Bosch glow plugs they are on the way I shall double check when the battery’s fully charged that I’ve got fuel at injectors again ....where is the glow plug timer relay located ???

Make sure you Copperslip the threads when you fit the new one's. The timer relay is in the ecu box behind the battery.
 
While your manifold is off give it a damn good cleaning out. Mine was coated in 3mm of egr valve shīte!! :confused:
 
Yes I spoke to the previous owner of the Range Rover he owned it ten years spent a fortune on it and he’s told me it’s the becm unit so I’m jst gonna remove it and send it off etc
 
Send it to Callrova in Hove if you send it any ware Rickthepick the owner is a member on here and the god with becm`s
