could a earth be the problem ? and were are the ECU and RElay pack earths at?

[DaveRob]

If the starter spins when you take it off the car and apply 12v but doesnt spin up when you try through the solenoid..... maybe its the solenoid..... If you have a multimeter connect black end to ground/chassis and red to the SOLENOID INPUT.... you should read 12V as this comes straight from the battery.... if you dont have a meter use a bulb and 2 bits of wire.... if no 12v then main cabl;e from battery to solenoid is broken..... THEN....connect to the output side of the solenoid main contactor somehow.... its posible your solenoid is bust...... failing this Im guessing....(due to the pump issue).... it may be imobiliser related.

12v at starter but problem still there

just a click from the relay module

got ignition lights ect but evrthing which works from the relay i.e fuel pump that manifold heater tingy and the starter dont work?

could this be an earth problem ? as with my carbd car if the wing mounted solinoide wasnt earthed properly it just clicked ?

were would the earths be for the ECU and Relay ?

[DaveRob]

but is the 12v getting through the starter or is the solenoid coil never energised .... find out if the solenoid COIL ( not the main contactor) gets voltage when you turn the key.... the main earths you should be looking at for the ECU are under the brake servo on the bulkhead ... they do get V rusty.... their are some on the other side as well.

right update

cleaned the earths and now when we turn they key to start we get a constant clicking from two yello boxers mounted near the relay module, there on the inner wing with semens wrote on

dave how would i check a dodgy imobiliser?

Been having this very same problem with mine. However it doesn't do it every time and it seems the more I use the car the less it does it - probably a duff connection somewhere and with use it sparks across and cleans itself a bit - maybe even the contacts in the starter relay?

Anyway - if the problem gets worse / comes back my next step is to rig a 12v bulb to the solenoid small connection. That way I will see if 12v is getting that far. If it is then either the starter is dicky or I have a bad earth. I have already been round the earths and taken them off and cleaned them - also the main feed from the battery.

Scottyegg, those relays are nothing to do with the starter, if they are clicking when you turn the key, then you have major wiring issues, and i would seek the help of an Atuo Electrician, we wont get anywhere with his over the internet :/

There is far too much speculation in this thread so lets try and clear this up.

You turn tthe key to start the engine, the engine does no turn over but the relay pack clicks. Is this a contuous clicking or is it only once when you trun the key and once when you release the key?

The starter motor does spin when you remove it from the car? Nott just that it is free to spin, apply 12v to energise the solenoid and the motor should run


There is nothing complicated in the starter circuit. What year of car is it and is there a factory fit alarm? The factory fit alarm/ imobiliser will prevennt the starter from turning, but would also prevent the relay working in the relay pack.

Lets say that the relay is working fine and energising as it should when you turn the key but the starter still does not work, check there is 12v at all the brown only wires on the large connector on the relay pack. Then, if that is ok, remove the large spade connector on the starter solenoid, brown with red wire. check you get 12v there when you turn the key to start the engine. If you get 12v there, the solenoid is goosed, if not, the relay pack is goosed, or its a broken wire, which i doubt, as its a fairly large wire, but its not totaly out of the question.


One thing i would double check is the engine earth strap from the bulkhead to the block, if this has broken or is suffering corrosion, this can cause symptoms similar to what you are experiencing. the Earth point in the boot is also another suspect one giving the same situation.

However, untill you can clarifly exactly what you mean by 'clicking' I cant really help any more than this

One other thing, has this just happened or is it only doing this after you have done some work on the car. Im thinking of the possability that the engine loom fuse links may have blown due to a short to ground? Have you done any work on the car?

[scottyegg]

thanks for that sprocket

right as you asked the click only happons when the key is turned to start the car, when u let go of the key and turn again it clicks, it is not a continuious click just when they key is turned to start. when we open the relay module we found that one relay engages when key is turned, this is the clicking noise. and nothing happons after that.


the start does work off the car by applying 12v to it also when crossing the solinoid and other connector(earth maybe)

i will check the engine earth straps and all brown wires tonight

were would i find this main fuse? and yes alot of work has been done to the car flip front welding ect.

This problem only happond one morning. it was working the day before and they next day we went to start it and we just got this signle click every time we turn the key.

another thing to note when the immobiliser is on or what we think is on and we go to start it we get a continuing clicking from one of the yello boxes mounted to the inner wing near the relay pack and it gets warm.

Thanks for the help sprocket and others.

Problem solved !!


there is a fusable wire which runs to the alternator dont at the front of the car

this had gone and needed replacing

I love my Job

Glad you go it sorted

Having the exact same issue with mine. But have replaced the fuseable wire and still doesn't work. Any other help or ideas woukd be great. Cheers

Better to post a new thread with a clear description of the issue you have, when it developed and what you have done.
