You really need to take a step back and start from the beginning here. I feel like you're going down the primrose path. Why are you concerned with the COR at this point?Jon, thanks for the links and tips.
C8 is the Circuit opening relay behind the foot rest.
Circuit opening relay
My 1994 FZJ80 was having an intermittent no start issue. Engine would crank and CEL light would illuminate but would not start, after a few tries it would start and then run perfectly. The no start occurred infrequently, maybe once per month. I tracked the problem down to the Circuit Opening...forum.ih8mud.com

In one of your first posts, you said that the CHARGE lamp doesn't illuminate with the ignition key in the ON position. That screams fusible link AM2 or the 7.5 amp IGN fuse. Look at the current flow chart in the power source section of the EWD.
In an earlier post, you said that you were getting +12 to ECU connector E7-13. Then you said you weren't getting +12 to E7-13.
How are you testing this?
Is the key in the ON position while testing?
Is your meter set up to read voltage?
Does your meter have a good ground for the negative lead?
Is your meter lead making good contact with the pin in question?
Are you checking fuses with your eyeballs or are you pulling them individually and checking them with your meter set to continuity?
There can be no guesses here and I can't see what you're doing. I'm trying my best to help, but I can only go by what you're telling me and it's not making
Your AFM is likely the issue.Latest update, I replaced the circuit opening relay and got the CEL. I tried starting it, ran for a few seconds then stopped. I noticed the cable was still unplugged from the MAF. I plugged it in, the CEL went away, but now it cranks with no start. With the MAF sensor cable off, the CEL does show now.
@jonheld I will check if the AFM can be repaired, else will shop for one, thanks!Your AFM is likely the issue.
The switch for the flap in the AFM provides the ground path for the secondary coil in the COR that fires the fuel pump. That's why the engine stalls shortly after you stop cranking the starter. The primary coil is fed from the starter circuit.
The fact that you get a CEL without the AFM connected and it goes out with the AFM connected tells me that someone removed the 2 Phillips screws on the connector housing and pulled internal wires off the traces inside the AFM housing. This can be repaired if you're very handy with a soldering iron and know what you're doing. If not, pick up a used unit from the classifieds section. There are several trustworthy sellers that part out 80 series.
Test the AFM according to the FSM first. Be certain that's the issue.@jonheld I will check if the AFM can be repaired, else will shop for one, thanks!
