No other codes when the eeprom is unplugged - if it is plugged in then several (all powered by same 5 volt circuit from ecu) - they are only being flagged because they aren't powered up

what are the other codes?

What's your town mate I'm near Falkirk if you need me to pop over?

13 27 51 all will clear when eeprom unplugged, none will clear when it's plugged in.

I'm in Lesmahagow bud, at this point I really just need someone with a meter to test their eeprom to see if it has same continuity as mine. If it's the same it doesn't rule it out but would cast doubt over it. Thanks for the offer

@badbaz you are blue now! you have the same faults as I have still do I chased them for ages swaped the rom with the one on my other truck still did it swapped the ecu still no change I reakon there is a wiring or pump fault but I am happy to check the continuity for you to rule it out tell me what u need I may get time this afternoon

@badbaz ill check that later mate

I have pulled the vac pipe off of the throttle body to stop it going into limp mode mate, well actually I have now removed the butterfly in the throttle body too! thats easy the egr has long gone on my truck too so the redundant plug is there ready to check.

my eml dont happen all the time it is intermittant, thats what makes me think wiring or fuel pump

oh and my rev counter does not work either

mine did have a burnt track on ecu yes, but i think that was caused by over charging with previous owner,

this problem same as yours still exists mate, and it happens with a known working ecu pluged in just with the ignition turned on the truck dont have to be started even for the fault to show its ugly head

@badbaz you dont have a power upgrade chip on this do you?

yes it piggie backs the ecu mate i think it was the animal that had them though

No piggy back here then

@123hotchef any joy with checking those values at all?

i will do that first thing this morning for you mate it was late when i got home last night

no worries mate i had not forgot the multi meter is sitting right next to me

@123hotchef thanks for checking (and replying in the wrong thread )

Just to confirm the rom WAS plugged in when you checked for the voltage?

doh wrong thread really! yes mate rom was plugged in for voltage check

That's great thanks - rom MUST be my issue - but it probably won't be lol

why whats the difference?

When mine is plugged in the 5volts is killed - unplugged it returns

i also have continuity between the green and bollox cant remember if it was the red or black now!

I only have black and yellow

Black becomes black on car side of loom and comes from ecu as an earth, I'll check that is an earth shortly

Yellow becomes blue/white and feeds from the ecu but it is a magic wire as I don't know what the symbol is on the ecu in the wiring diagram lol At pin 72 on the ecu in diagram
