I'll check the fuel pump, the EFI fuse isn't blowing anymore, I replaced all the fuses but the 80A alternator fuse, and went ahead and jumped the alt fuse with an inline 50A fuse (That didn't blow). With the alt fuse jumped, the truck cranks, all the interior stuff works, it just won't fire. The smoke came directly from the ECU, so I'm pretty sure it's dead. Where is the AFM sensor located?

My father in law has a 1990 4runner but his (and his ECU) are 5spd and won't hook up from what he says.

I found and bought as 1990 3VZE A/T ECU from ebay for around $100. None of the local junkyards had anything.

Here's what I think happened: the alternator died, popped the Alternator fuse under the hood, which killed power to the interior of the car. While trying to jump blown fuses to get it to start, my well-meaning buddies accidently jumped 12v from the ALT to the EFI fuse under the hood, making the magic smoke leak out of the ECU. I should be mad, but there ain't nothing I can do about it, I reckon.

Where can I get that special 80A fuse that goes in the alternator slot under the hood?
