hi all need help to cure this fecking fault code 26(injection valve cylinder 2 voltage too high) ive tried moving the injectors but code 26 keeps coming back so it must be a wiring problem ,so my question is where do i start to look for this?
yep mate its the only fault code thats coming up and it only seems to come up if ive been givin it full chat/nope the car seems to be running fine/and ive tried swapping the injectors about but fault code 26 remains,so im of the opinion that it must be a wiring problem so i was wondering if anyone else had come across this problem and if so how they cured it?,,,,,,,,,,,,,,,,,,,,cheers craig
thanks for the help ,ive just been out and checked the connector(s) to the injector(s) ,all seems to be fine and nothing looks dodgy at all,the four injectors have red/ blue wires all joined up(factory join) and this wasnt insulated though,so ive put some tape around the join,,if the fault code 26 comes back again would it be ok to run a new wire from injector2 to the appropriate wire near the ecu(if i can find it)brown/yellow for injector 2,,,,,because what i can see of that wire looks ok but i cant really tell beyond that???
check the insulation across the four red/blue wires it should be less than 1ohm. if not then plum into the loom half way along and do the same test. then you can find out where (if) the loom is faulty.
infact come to think about it, im sure the red/blue wires also tap in to the fuel pump feed. dont quote me on this tho i'll check the diagram 2moro and i'll fone my m8 @ vauxhall see if he knows anything.
yeh m8 ive reset the ecu a couple of times now ,my ecu light isnt on constant ,it just flickers a couple of times then stores 26,when ive given it some stick,,,,,,,,,,,,,,,,,,,,,ive managed to work my way through a couple of problems with this engine without it costing an arm an a leg but this one has stumped me, however if i come across a dodgy bit in the loom would it be ok just to use spade connectors and a fresh piece of wire/cable ? or is it a new loom job? cheers craig
you should be able to do this yourself m8. u ok using a voltmeter and how to do different tests on it?
yes it is ok to put new wires in, best way is to use a soldering iron to join the wires together. keeps it neat and alot thinner than spade connectors.
if it comes to it craig, 1 weekend best bet is to take the loom out from the engine bay and check all the wires individually going back to the ecu pin (i did this with my valver. good fun). that is if you cant find the problem when doing some simple resistance/voltage tests.
im doing an engine change on a rover today but i will be in l8r tonight.
dont let it get to you m8, its probably so simple you'll laugh about it after
