Efi Relay Clicking

[Carrie]

Please can someone help. I have an IS200 52 plate. The efi relay is clicking frantically - it's baffled several service mechanics, specialist auto electrician and Lexus dealership. First happened 6 months ago, drained the Battery, couldn't stop it, then it just stopped by itself. The fault wouldn't reappear when it was in any of the garages so they weren't able to trace it. Then it happened again a month later, took it into the Lexus dealership, fault disappeared again when I got there, so they couldn't trace it, but they thought it was something in the ignition. They removed 'excess grease' from the ignition. It was fine for 5 months now it's doing it again and I'm desperate to find a solution as I rely on my car for work, but worried no-one seems able to solve it. Help!! It stops when I put the key in the ignition, even without turning it.

For info: The above and I have eliminated: The relay switch itself - swapped with the horn relay - still clicking; all earths been tested and fine; it's not water ingress on electrics as happened when no rain for days; Battery absolutely fine, as is the alternator; key had new Battery.

Desperate to find a solution quickly. Please can anyone help. Many thanks.

Hi this happened on a blokes from works car and it turned out it was down to a bad earth connection on an aftermarket alarm . I know this has already been checked but a second opinion wouldn't hurt.

Thanks for your reply. My alarm came with the car apparently and in fact both the Lexus dealership and another autoelectricians checked the earths and said they were fine, but a hands free set was fitted before I bought the car - could it be that perhaps?
