You might want to check your ecu grounds, and maybe the relay above the ecu (forgot what it's called).

correct!!!

So, after you recheck your battery ground and fuses (and their conection with those two bolts on each 30A and 80A) try to recheck your ECU ground...

In the manuals you have the exact procedure... find the right pins and turn the key on, try to ground it... E1 I believe with ground on the ECU conector...

You have one ECU relay in the engine bay, one up the fusebox by the drivers legs, and another where the ECU is...
Also, recheck your circut breaker... Take the glove compartment out, it's the big green relay...

Althou, relays drop dead verry rearly... check your fuses and conections first...

I bet my money it's a loose contact on the + on the batery... that 30A fuse is loosing conection... at least that what this sounds like to me...
