New toy WILL play :-D

like i already said they are powered consantly with a +12 they work on a negative pulse you see - they only fire when they get a negative.

What he said - they take the +12V through the main relay, on the same line as the coils - since you are getting sparks - except on a dodgy plug, and you are getting fuel - it\'s flooding - it\'s safe to say the circuit is good.  What needs checking is how much time they are on - when the switch is set to IGN, but the engine isn\'t cranked, the Injectors should be off and defo not clicking.  It they are firing, then the loom may have a short to ground.
 
A bad ground to the ECU or the sensors is more likely to cause the relay chatter problem.

Sorry did\'nt make myself clear.

not had chance to play today and might not get too long with it tomorrow - i will test the ECU tomorrow and then start looking for earths ( now that should be fun !! )

how are we today ??

had another few hrs on the car tonight ( i bet my elec will will be HUGE )

not much to report really - still doesnt run though !! LOL

checked the ac relay at the front - this clicks on and off as it should ( when its off the car )

check the main relay again in the top corner - this is OK - now then - the interesinting bit here is that when you remove that from the car and put the key in - the relays click - but thats it ... just click once and then silence ( this is prob cause this supplys them with the power )

add this back in and they all click like mad

checked the BAC valve wiring - and this seems to be earthing OK around various parts of the engine ( so that looks like the eath is ok )

the ac relay thing earth is OK aswell - as this beeps thru with various earthing points

we had a look at the ECU wiring .. crickey there is a lot of wires in there isnt there ... looks OK though - but a bit of rust dust ( if that makes sense )

so we are still not 100% sure what we are looking for

the main stuff seems to earth OK - so why the clicking ??

the only thing we can think of ( and probably said this 1000\'s of times ) - the stuff that clicks seems to be on the side of the ECU outputs - so is the ecu clicking them on and off

we are also struggling to find some components - but i have forgotten their names !! LOL

the clicking happens in all auto positions - so not sure if this is an indication of a problem ?? ( again cant think exactly what i tried it in )

but it still clicks prior to cranking - so what is the ecu doing ( or the relays and stuff ) prior to being cranked ??

not tied the ecu that prof sent back - if i get 1hr on monday night i might pull the ecu out the coupe just to really rule that out of the equation

apart from all this im still open to suggestions

Does it have some kind of immobiliser on it stu? It maybe something as simple as it needing to be reset.

[Grizzly]

A bit of a Guess but could the Ign switch be faulty?

The other thing i was thinking, if there has been that much water in the car to put a water mark up the side of the ECU has it been in a Flood etc?

[FD3SNuttah]

we sure the plugs are ok and not rusted to hell?

im really suprised you havent tried the ecu from the coupe!??
theres a short circuit somewhere. id try a different ecu

Not tried your original one Stu ?  I would give that one a go, a least that rules out any funnyness with the different ECU models.
 
Still think there must be a wiring fault somewhere.
 
As far as I know, the ECU will do some sort of self test and check the inputs/outputs each time you switch on - it\'s possible this test is going wrong :2eek

[grinder]

thats what i was thinking prof - its like its just hammering them to get some sort of feedback from them

im slowly getting very intimate with this car

how would an ECU test go wrong though - unless this is down to a bad earth somewhere

we are looking at starting again just with the ECU pin out diagram and working it a section at a time

ignition ... hummm you could be right - but my mate is convinced that we are OK on that side

its great when you have a problem no one has come accross EVER !! LOL

more ideas welcomed

You only need to hit the Button Once Matey

[grinder]

yeah cheers chris !! LOL

the t\'internet at work is always playing up - so its a bit of a random draw if it posts or not !!

[FLAT4MATT]

Still not got it started? Can\'t believe your luck, thing is it\'ll be something really small and really stupid, once it\'s found you\'ll be sorted... Once it\'s found that is...

Did i see you this morning? In the Rover?

[grinder]

Yeah i was in the rover today

didnt see you - where was you

and yeah once its running it will be down to something silly

been reading up about the earths and the resistance of them - its getting techincal now though

this still going? no luck replacing the plugs with the ones from ym car then ?
