91 ecu location

[toojayzee]

I was told the ECU for my 91' 80 is under the right side kick panel.
I see nothing there. I looked over and see what looks like a heatercore and box assy.
What am I missing ?

Theres a small box up there thats only 3"x4" and has a single harness in it. Thats not it is it ? I figured that was just heater relays.

Thats it.
Its not that complex of a truck.
of course taht is the engine ecu, there is also a seperate trans ecu, and a s***e load of relays under the main body of the dash.

Thats shocking. Im used to toyotas with huge ecu's with at least three harness plug ins.
So if they are not that complex then why on earth do salvage yards charge 3-400 bux for them. You would think they would be a dime a dozen.

Supply and demand.

For whatever reason, there are supposedly no new ones available in the US.

Edit: Unless an FJ80 (3FE) uses a different ECU than an FJ62 (3FE).

I pulled the box this morning. Not the ECU. As it turns out it was just the radio amp.
But upon closer inspection, you take the glovebox out and voila there is is. It is what I expected, the typical toyota ecu with three harnes connectors.

Still dont know if the ecu is the problem or not though ;-(

Covered in another thread?

[toojayzee]

yea in another thread but people stopped responding.
I did a minor tune up and now the rig wont start.
I did plugs,wires,cap/rotor,pcv,oil/filter.
I cleaned the AFM with brake clean. I replaced the AFM with a known good unit. Nothing. I replaced the igniter/coil. Still nothing.
I get spark. Im pretty sure I have fuel. I pulled the return line off and get fuel.
I replaced the main relay under the hood. Havent changed the C/O relay but I bypassed the fuel pump with a jumper in the diagnostic port.
Ideas ?

 

[CJF]

Oh yeah; you're the AFM guy!

Sorry, but I really am out of ideas.

Hang in there,
