Help! Was there ever a solution/fix to this?
I have replaced:
Fuel filters x2
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 Winibego v6, 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.
Still think its a oxygen sensor?
TPS isn't adjusted accurately?
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). Then it would work like nothing is wrong.
Now I can't get the Engine light off 99/100 times.
Thanks for any immediate help, expertise or thoughts!
