Just to add to this...

I had the same problem happen to me and it WASN'T the fuse. I thought it was the fusable link on the back of the cigarette lighter. There's a TSB from Toyota on this. Anyway, I changed that and it worked for a couple weeks. Then is started going out again. The fuse box up under the steering column was NOT the culprit. There wiring underneath the floor about 6 to 8 inches in front of the driver seat. There another fuse box there. That was the one that was causing a problem. Something got loose with that fuse box and now everything has worked ever since. It's REALLY in a bad spot and is easy to step on or kick. But at least now I know for next time...and so do all of you!

Seriously, could they put that goddam fuse box any farther back on the kick panel? The fuse box on the Cobra is so easy to get to...

Its ridicoulous isnt it? In fact id argue the placement of most things on this car for a mechanical point of view is down right absurd...

Its like they made the car hard to work on ON PURPOSE!

Fuse hard to get too.. tune up spark plugs are hidden under TB, timing belt wasn't that bad, but bolts for the tensioner the one in the back was in a stupid place. Took me awhile to figure out the right angle to get the egr valve off when dealing with that issue... If you want to remove fan shroud and radiator you need to remove the battery tray.

In fact Id argue the place where the intake and exhaust manifold is is silly to begin with! Why are we making the coming in air go over the hot engine block below it again?

They DID in fact do it ON PURPOSE! These cars were purposely made to be worked on by Lexus techs at Lexus dealers using only Lexus parts. Wich is the main reason its a pain in the a*s to get part numbers too.
Also parts are ment to be replaced , on these cars NOT repaired.
