Hi Guys

Recently this issue started developing with my car: 1996 SWB 3.5 equivalent to the SR in the US

while attempting to start the engine once I move the key to hit the starter motor, a Buzzing rely sort of noise is heard from the ECU on the kick panel on the passenger side. the starter would not kick in unless I back of and just hit the starter again and it would start normally.

now this issue has not yet developed into a problem, but this being the ECU I thought there might be something to do with it before it gets worse, or the ECU fries.

This issue has no pattern to is what so ever, it happens early in the morning as well as just restarting the engine at the petrol station, cold days & hot days also.

Is this a Serious issue yet? is there something to be done to fix this?
