Geoff Dixon Posted February 14, 2003 Share Posted February 14, 2003 Have just finished most of my winter jobs on the car (1.6 K series) and thought as its a nice day I would start it up and go for a spin. Wired up ther fully charged battery and it wont start. Engine spins OK, all the warning lights come on, everything works apart from it wont start. One of the jobs I have done is to fit new alternator so have been messing with the electrics. When I turn the ignition on I CANT HEAR the petrol pump charging - in the past immediately on turning the ignition partly on you could hear the pump charging itself for a few seconds. This is now not happening. Also I have an Emerald ECU unit. The red warning lamp is not coming on suggesting the unit is not powered up. I have checked all the fuses and wiring - I think. Is there any chance it is the black Multi Function Unit which is connected to the wiring loom by the 2 large block plugs. Is there any way of checking this - whatever it does? Help guys There is obviously no power going to the fuel pump or the Emerald so the fault must lie in the circuit from the ignition switch to these ( I think !!!)

Mark Piper Posted February 14, 2003 Share Posted February 14, 2003 Immobiliser? does it have one?...ECU fuse (see Al Crickmore's thread...) Link to comment Share on other sites More sharing options...
WILL FLY Posted February 14, 2003 Share Posted February 14, 2003 Geoff Check the inertia switch. Passenger side of scuttle in engine bay, has round rubber top, press top and it may click. Should then start Roy See willfly.net for more info. If you don't spin you ain't trying Happiness is knowing you have just a tad too much power Link to comment Share on other sites More sharing options...
Geoff Dixon Posted February 14, 2003 Author Share Posted February 14, 2003 Tried the inertia switch - does not click and has made no difference. WIll the inertia switch affect the supply of power to the petrol pump? Link to comment Share on other sites More sharing options...
Geoff Dixon Posted February 14, 2003 Author Share Posted February 14, 2003 Have found a short washed-out-pink coloured wire from the immobiliser box which looks as if it used to have a connector on the end ( but now does not) and is hanging loose. By the length of it I would suggest it should go to the ignition switch as there is nothing else near enough to connect it to. Any chance someone can have a look at theirs and see where this wire is meant to be connected. Link to comment Share on other sites More sharing options...

Rob Walker Posted February 14, 2003 Share Posted February 14, 2003 The washed out pink wire is left free at one end, its the aerial for the radio receiver part of the immobilizer. Link to comment Share on other sites More sharing options...
Chris W Posted February 14, 2003 Share Posted February 14, 2003 Geoff I know the inertia switch wasn't the problem as you have tried resetting it, but just to answer your question..... the inertia switch is in series with the fuel pump and so therefore would indeed disconnect power to the pump if it is tripped. 1.8K SV 140hp see it here Link to comment Share on other sites More sharing options...
Chris W Posted February 14, 2003 Share Posted February 14, 2003 Geoff As you have had the battery disconnected, have you re-synchronised the immobiliser with the plipper? I'm only familiar with the Rover immobiliser which needs 4 clicks of the "arm" button on the plipper to reset it. I had a similar problem to you the other day now I recall and that solved it. Fingers crossed. 1.8K SV 140hp see it here Link to comment Share on other sites More sharing options...
Richard_E Posted February 14, 2003 Share Posted February 14, 2003 IF you have an emarald, one of the settings allows you to turn off the immobilizer in the software. The emerald is red with power and green when cranking and engine running. Link to comment Share on other sites More sharing options...
John Howe Posted February 14, 2003 Share Posted February 14, 2003 If you still have the original Rover ECU, try replacing that with the Emerald ECU and see if it will fire.

allegro Posted February 14, 2003 Share Posted February 14, 2003 I'm sure you've already looked, but check the 20Amp ECU fuse. If it's OK, change it to a 25-30A anyway. Andy Mac C7 GON 😬 Team Langoustine. Hard Core Prawn here 😬 Link to comment Share on other sites More sharing options...

Geoff Dixon Posted February 14, 2003 Author Share Posted February 14, 2003 OK have now changed the MFU unit and no joy. Still cant get the red light to come on on the back of the Emerald which I think means it has no power. Going to go through every single wire I can think of, check the fuses again, check the inertia switch etc Any chance it could be the Emerald unit?
