All faults were triggered on cranking indicating low voltage. The revving is most certainly the ECU not receiving a signal from the CPS. The engine is then running on speed signals from the number four injector.

Hi Wammers thank you for your input,I will get battery tested today as the cps was replaced at the end of last year could it be faulty?Any way of testing it?I know you said cps wiring could be faulty do you have any pointers where you would start testing looking first?
I appreciate your invaluable experience One thing no one can buy is experience.
thanks

Check pins 13 and 47 for cleanliness on connector to engine ECU in box behind battery. Disconnect battery before playing with this. https://www.nanocom-diagnostics.com/downloads/preview/p38-bosch-edc-nanocom-evolution

Hi Wammers checked pins 13 /47 looked clean and fresh.Got battery and alternator checked with local auto electricians who specialise in alternators and starters batteries etc.Battery and alternator good.Checked and cleaned all earths around engine and engine bay.felt brave enough to test drive all went fine for ten mins then boom alternator fault warning on dash then rev counter zero engine idles at around 3000rpm but rev counter tries to come back on line and the kangarooing starts.Will get more alternator Battery testing tomorrow had to work late and ran out of light.
Thanks again gents

Hi gents more investigating this morning and I cant see any corrosion or damage to the wiring at the cps.Entropy what was the condition of your cps wiring?Can anyone tell me what the wiring behind the alternator is for the wiring isn't for the alternator as far as I'm aware when I unplugged it I noticed a lot of corrosion the wire colours are red and white and white.

Looks like the fip cycle valve multi plug.You may be on to something there.clean it up.

Use electrical contact cleaner and a small needle file, that should do it.
Don't have a clue maybe pressure washing and use of aggressive cleaners. Just clean it up and make sure it has a good contact. If all else fails Lemon juice is good but it MUST be well rinsed off. Then contact cleaner and a blow out.
Hi gents got the timing device modulation wire connector plugs cleaned up.I also found the reason why it happened some one has cut a piece from the rubber boot that fits onto the connector they must have cut it on top then turned it to the bottom{hidden}Grrrrr your right mate salt water from road salt has probably got into it.had footer with the cps sensor wiring whilst engine idiling, couldn't get the fault to repeat.So took it for a spin and it was great for 10 mins then Boom Boom Alternator fault on dash no rev counter high idle and kangarooing.Where to look next?Any help apptreciated.BTW when I cleaned the timing device modulation connector the pump started a vibrating noise never heard it before.Wammers could the cps be breaking down?
thanks

I think that could be a fair assumption.
