I'll give them a nudge or two as you say worth a try ,getting a couple of purple relay from Albitz tomorrow to eliminate them thanks Symes

[Toledodude1973]

just tried purple replacement relays and no change ,need someone Ipswich area to try and read any codes with pukka tech 2 reader i'm obviously willing to pay , i fear if i get just any mobile mechanic its just going to cost me with no result ...help please

[albitz]

I will contact someone not that far from you who has one,as discussed this morning.Shame changing the relays didn't do the trick.

[Toledodude1973]

Thanks Albitz running out of ideas mate!

worth a try though  . . as they were "clicking " as well in unison  . . .  it  may have worked .  But  you have now  eliminated the complete throttle body assembly & the 2 mauve relays.

next step as Albitz says Tech 2  read 

[Lazydocker]

I fear that even with a proper Tech 2 the same communication issue will exist Paul

Check all the earths and connectors as suggested

EDIT: I have been and looked at this car and whilst the throttle bodies are chattering there is a comms issue... Unplug them and plug them back in and the chattering stops, code reader connects and car starts.

Strikes me as an intermittent earth fault TBH

[Toledodude1973]

thanks for reply and previous help ,can't start car at all now ,will check earths etc. are the main ones near the battery area?

[henryd]

Get a jump lead and try connecting from battery neg to engine then body while ignition is on to see if clicking changes,may prove an earth fault

[Big_Al]

just curious Paul,   has the battery been off lately . or did it go completly flat whilst the car was stood up & not used ?

Would agree with the jump lead "earthing" theory  . . . worth a try 

[Toledodude1973]

Yes Al battery was flat when laid up but started quickly after charge will try with jump lead tomorrow thanks everybody

Right.. Let's try eliminating some things. Firstly, which relay is clicking? Can you try removing the purple relay that's nearest the passenger side wing? This is the fuel pump relay. It won't start with that out, but is the clicking still there?

If so, take out the green 30 A fusible link in the fuse box above the battery positive terminal. Check the pins are clean and that the fuse is intact with no cracks. Put it back and maybe give it and the wiring between it and the ECU a wagggle to see if it influences the clicking noise.

Check the 3 large round connectors behind the battery are firmly plugged in. Again, give them a waggle and see if it influences things.

Check the 2 multi-way connectors on the ECU are firmly plugged in. They aren't prone to working loose but someone might have been there before...

Check battery terminals and all wires feeding from them are tight.

Check the grounding point behind the power steering pump on the engine is secure and also the one on the body just below the battery..
 
Check the battery voltage with the ignition on. Could be that it has a dead cell or hasn't recovered from being drained, and the ECU is dropping out due to low voltage.

open them and check connectors as did say they open/lose contact

thanks for help, results:Removed passenger side relay = throttle clicking remains
                                Removed engine side relay = Throttle clicking stops
                                Removed 30A fuse,cleaned, refitted and wiggled but no change in throttle clicking
                                Checked 3 Large connectors and moved wires but no change again
                                Checked ECU plugs and all fine
                                Checked earth and battery terminals and all okay
                                Have now put battery on overnight

Hope this helps to eliminate the possibilities of the problem. Thanks again, Paul.

so try this-disconnect fuel lines to fuel rail-17+19mm put the open fuel lines into a jar and get helper to turn engine over-to see if fuel getting to engine-maybe pump/filter-no fuel=no go or try taking spark plug out-wet/dry

[Toledodude1973]

Thats the three big ones symes yes? how do they undo?   thanks mate
