Griffith 4.0 1992

[Vixenlad]

Hi there, looking for some guidance. My engine in the griff suddenly became underpowered and very very lumpy as if not firing on all 8 cylinders. Did the usual checks, plugs, leads ect but no success. Contacted local mobile diagnostic company who said ecu was faulty and not sending a signal to 2 & 4 injectors. Sent ecu off to ECU Testing Ltd for repair but they contacted me to say they cannot work on this type of ecu which was a surprise to me. Any ideas what my next step is as I am getting withdrawal symptoms with the griffith being off the road.

Thanks for your reply. No I'm not 100% sure and that's why I was hoping to get the unit checked out before needing to purchase a replacement and then finding out the fault was still present.

Any further ideas gratefully received.

Yes, it is a 14CUX ecu. If that means 2,4,6 & 8 injectors are out would the engine run at all ? Do you know of any company that can test this type of ecu to confirm if this is indeed the fault. Thanks.

Hi there, I'm based in Pontefract, West Yorkshire and used AA Services for a mobile diagnostic but I too am unconvinced that it's a ecu related fault. Just need a second opinion before I splash out on a replacement unit. Such a shame the griffs off the road with such cracking weather 😦

Thanks, have e mailed ATP to see if they can test the unit. Any local Griff owners willing to do a quick swop or recommend a diagnostic facility for the 14 CUX in Yorkshire.

Thanks, will keep my fingers crossed.

Hi Pete, thanks for your reply. I sent the ecu to ATP Electronics a couple of days ago to get it checked out. Rang them today and they said the unit and software checks out ok so it looks as if my local mobile diagnostic man got it wrong. Problem is I have shelled out £140 with the cost of diagnostics and testing and it looks as if I will be stuck with the original problem. Will keep you posted if that's ok.

Hi folks, thanks for the tips, will certainly give them a try. As for finding someone with TVR experience, when the cars not in a driveable condition and there's no one local, then needs must. I would have thought any auto electrician worth his salt ( and obviously mine wasn't ) should be able to fault diagnose what is basically a Rover V8 with software enhancement, or am I fooling myself ?

Thanks Brian, will check out Selby and see if they are mobile. Cheers.

Thanks for your reply. Have checked condition of plugs and they look fine, light chocolate brown coating, Magnicor leads all good too. Distributor contacts cleaned and look fine also arm in good condition as well with no signs of cracks.

[Vixenlad]

Ok thanks, will try that.

[Vixenlad]

Good idea, will do. Thanks.

Hi Scottliv & Saxon, thanks for the tips, will certainly check out the ecu scart connections. The TVR man sounds really good but unfortunately I live a bit too far away in Yorkshire. Thanks anyway.

Many thanks, will ring him today. Regards.
