Trying to check codes with paperclip and does not work??

[WarriorSe7en]

The original jumper wire that is supposed to be there is not there on mine.. probably got chucked a long time ago

Help! Was there ever a solution/fix to this?
I can't seem to pull code-

I have replaced:
Fuel Pump
Fuel filters x2
Oxygen Sensor
MAF Sensor
Throttle Position Sensor
Plugs and wires.
Now I sent in my ECU because we can't pull a code even when the engine light is on. The OBD1 does NOT read anything (used several different OBD1 devices). I also tried to trigger the code by using metal contact pin in the Diagnostics box (to watch the engine light flash)

Please help. This is my 1992 Toyota Pickup 3.0 (Winibego) , I am currently stranded in North Utah, My home is in Seattle.

Took it to a shop they said had to be the ECU since it wasn't allowing the OBD1 to pull a code. The ECU was sent in and tested and they couldn't find ANY issues with it.

I was having the same issue as described above.
I found a temporary fix that lasted awhile-until the past week, If I disconnected the + battery and removed the EFI fuse after each use, put them back before I decided to drive (both immediately). Engine Light would often not appear. Then it would work like nothing is wrong. When light is on I have very little HP.
Now I can't get the Engine light off 99/100 times.

Thanks for any immediate help, expertise or thoughts!

When you say very little hp
Like you can't get more than 2500 rpm
Cant go more than about 35 or so mph
Even if you mash the gas pedal it's only part throttle?

That, to me, seems like wagon would be in 'limp mode'

There are several things that can cause the ecu to do that. They're in the fsm somewhere. I think way to much fuel in the cat or a knock is detected are two reasons for that. Maybe search Limp Mode for the skinny
