Not sure why the computer would be making any noise since everything inside it should be solid-state. Are you sure it isn't another relay under your dash...maybe the fuel pump relay if you have EFI? I'm just guessing, so I could be way off.
If all the wiring is ok, it just might be time for a starter
Ok guys a little more info on this. It is an EFI plowking, but I am certain the click is comming from the computer. I pulled it out of the housing (helps when the pannel isn't screwed down ) and turned the key over with it sitting on the floor board next to me. So I am certain that this is where the sound comes from. I still haven't looked at it yet, but I am pretty certain that I will find the wiring sound and the starter working. Can anyone help explain why that sound would be comming from my Computer?
Should have bought yourself a JEEP and you wouldn't have this problem.
Is that a Toyota factory ECU? There is nothing in there that clicks..Clicking when the key goes from both ACC to ON, and from ON to START positions are perfectly normal since relays are used to handle and split larger amperage loads to the various circuits on your truck.That clicking noise has been there the whole time, but because the buzzer is on (when going from ACC to ON) or the starter is engaging (when going from ON to START), you just never heard them.If it's a quiet click that can only be heard within about 5 feet from the truck, then that clicking is normal, it is just the relays working, and the starter is not getting any voltage at all, or it is completely junk.BigMike
You are talking about a Relay, not a Circuit breaker, right? Talking about the OCR, or Opening Circuit Relay?I've never ever seen a circuit breaker in any Toyota truck, other than fuses, and I've never seen a circuit breaker in any of the wiring diagrams I've read.You've got me courious now, could you take a picture of it? Glad to hear you are getting it fixed and back on the road!
Ok man, you got it right "Circuit Open" relay
