starting issue - GT40

[CCC79]

HI all,

I have a year 2000 SAN wit the GT 40. I would appreciate some help from you on this. It has been getting progressively hit and miss on starting lately. It is keypad ignition and when I attempt to start, there is a loud click and all electrics cut off ( both lights on keypad die). I can bypass the positive wire to the solenoid with a jump lead from battery and it will fire up. I cannot seem to get hold of any info on the engine and I am in UK so dealers are not very good.
I have searched the boards and the only thing I can guess is the starter relay? I take it this is under the ECU and has a positive wire in and a positive wire out ( to solenoid).
Would I be right in thinking change this first or is there something else I should check. Parts are very expensive here so I want to narrow it down as much as poss.
I am competent mechanically but I am not so good at tracing electrical. If it helps, I have tested voltage to solenoid and it is 12.8 ( same as battery ).

Appreciate any help fellas, the sun is out for once in Blighty!

RE: starting issue - GT40

if your getting a click from the motor box whenever you press the start button. its most likely the starter relay. almost positively the relay. exact same thing happened to me at the beginning of last summer.

Whataboat, cheers for that, I was using TVski and thought they were the only UK dealers. Have had mixed service from them......

Either the starter relay or a corroded connection between the battery and the relay. Could be as simple as a corroded battery clamp or battery cable where it meets the clamp. The dash pod dying after attempting the start makes me suspect a corroded or loose connection to the battery. If it was just the starter relay, I don't know that the pod would die after the attempt. That symptom points to low voltage, a battery, clamp, cable, or grounding issue.

M3 Fan, yeah I thought the same originally and cleaned all connections up but it is still happening. The noise it makes when cutting off is quite loud, almost like a stereo tripping out ( a bass type noise - hard to describe)
Anyone able to tell me for sure if the pod would die after trying to start if it were the relay?

Thanks fro the help all.
