Alright chaps n lasses,
Well we removed the ECU and replaced all the capacitors with new ones.
Very rewarding job, but I recommend anyone attempting it to have all the right tools etc and practise soldering/desoldering before touching the boards.
I also found 'youtube' helpful to watch others doing the job. Desoldering braid is very useful and remember to 'tin' your tip for good heat transfer.
Anyway, apart from learning to replace capacitors, the job yielded nothing!
The truck ran as before with late changes and no o/drive.
Prior to fixing this the speedo was replaced with a used one as the original had stopped working and a g/box guy said it may fix it. Would the speed sensor affect things?
Also is it now likely to be the g/box solenoids that are the culprits and if so is it a possible home diy job?
Some guys have a good used box for sale here and we are considering this too. Â£200+ courier + fitting.
What do you reckon?
Thanks for looking and any input!
