The starter circuit is pretty basic.... if your battery is indeed fully charged.... then starter motor would be suspect next... take it off and try applying battery voltage direct to see if it spins.... but I would double check the batery voltage with a meter first.... just because you put it on charge dosent mean its charged up

Hope this helps

its not the starter thingymabob

its the ignition relay box on the top rights of the engine bay the black boxm, which is clicking and nothing happoning

KUDOS TO SPROCKET FOR THIS EXPLINATION

When the key switch is turned to IGN 12v is supplied to the ECU on a white wire this powers the ECU. The ECU will then initiate the fuel pump for 10 seconds and then de activates it again if there is no further activity. Turn the key to CRK the starter is initiated (if the imobiliser/alarm is off, where fitted)..... note at this point the engine is turning over..... NOT what you describe)THEN Activity is recorded by the ECU on the Crank Position Sensor. The ECU then initiates the Main relay. This provides power to the ignition coil, stepper motor, purge valve solenoid, and ECU directly on the brown pink, and the injector via the ECU. The engine should now start. Once the RPM is above a predetermined RPM the manifold heater is initiated until the coolant temp measures 75c or more it is then de activated. The Main relay, and fuel pump relay, are the only ones to be energised when the engine is running and fully warmed up.

Ergo..... if the engine isnt cranking then the problem is MOST LIKLEY to be the starter circuit first ...... like I said remove starter and apply 12v to see if it spins....

hmmmm so you think it could be the starter?

[DaveRob]

Is possible.... and fast and easy to find out.... then we can move on to more complex diags...lol

[scottyegg]

starter motos spins freely


also to add

The fuel pump dosnt kick in like usual you know when you get that noise for about 10 seconds

ALL THE FOLLOWING IS SPROCKETS WORK AND IS IN THE PINNED AREA

Coil side of relay pack (small connector)

+ve supply to the relay coils

The main relay is permenantly supplied with 12v (internal), the fuel pump relay is supplied with 12v from the IGN position on the key switch (white), the manifold heater relay coil is supplied with 12v when the main relay is energised (internal but common to brown pink), the starter relay coil has two options depending on year. One, the starter coil is supllied with 12v when the key switch is turnd to CNK (white with red). Two, the starter coil is supplied with 12v when the key switch is turned to CNK (white with pink). Note the latter, the wire from the starter switch is white with red, then changes to white with pink through the body to engine loom connector.

-ve supply to the relay coils.

The main relay is grounded by the ECU (white with pink), the fuel pump relay is grounded by the ECU (black with purple), the manifold heater relay is gounded by the ECU (black with pink), the starter relay has two options depending on year. One, the starter relay is grounded (black pin4). Two the starter relay is grounded by the alarm ECU ( white with red). Note the latter, the wire from pin4 of the relay pack changes from white with red to white with pink, through the body to engine loom connector.

Main switched power supply (large connector)

All four relays are fed with 12v from the battery (brown). Main relay switched live is brown with pink. Fuel pump switched live is brown with slate(grey). Manifold heater switched live is brown with blue. Starter switched live is brown with red.

So read Sprockets work and check the relay pack top left.... the description is their or do you have a connector to the pack that has come adrift...... sounds like a combination of fuel pump relay and alarm / relay so maybe a connector adrift on the pack?

[scottyegg]

packs been replaced just bought a new one both old and new do the same thing click when key is turned to start the car

cleaned all connections

(no fuel pump)
(imobaliser still works)
(starter works)
just no ignition/fuel pump

[scottyegg]

update!!

well news

the clicking is coming from one of the units within the module

when the key is turned this one move across but nothing happons?

is it posible that the ECU may not be starting the fuel pump/ starter and the relays are not at fault?

[DaveRob]

This is starting to get difficult...lol.... to clarify... the starter works when you have it off the car.... but it dont work through the starter solenoid.... the fuel pump isnt working at ign lights on...... and you have changed the relay pack for a new one. this is sounding imobiliser related... and thats Sprockets area.... you arnt far from me and Id be happy to call over to give you a hand if Sprocket cant shed any light on this by morning.... wait til morning and if we dont have any other ideas posted I can come over and give you a hand if you want. PMd also

I am also confused :S

Does the engine turnn over or not when you turn the key? as that is what you said you were having problems witth initialy

[scottyegg]

no the engine dosnt turn over as soon as the key is turned to (start) the relay box clicks and thats it
