92 FJ80 Facebook link has the details

I have fuel at the cold start injector during a no start.

Yes. The next stop on the troubleshooting train was going to be to verify +12 at the injectors during a no start. But, I haven’t had a no start since July so I decided to have a look at the harness to see if there was anything obvious in there.

The last time there was a no start (July 4) I was able to verify a strong spark.

That wire is the only problematic looking thing I can see in the harness in that area. Looks like I’ve struck out again. :bang:

Did you just know that off the top of your head?

I finally got around to pulling the intake to look at the wiring harness underneath. I did find what appears to be a suspicious looking repair to this blue wire that goes to a ground below. So far I’ve been unable to determine what that blue wire is.

I've just printed pages as needed. :meh:

Just to be sure. The B-G wire is the +12 from the ign circuit and the W-L and Y go to the ECU where the circuit gets grounded to fire the injectors. So, I need to verify that I have +12 at the B-G wire with the key on. Is this correct?

That's the plan. I'll have to wait for it to die on the road again. Hopefully it doesn't take another 8 months.

The harness at the firewall looks good to me, the rubber boot is still intact and the harness itself appears unmolested. This has been over my head pretty well from the beginning. Any testing requiring an oscilloscope is definitely outside my ability.

Would you check at the injector, the ecu or both?

Finally died(temporarily) today, Here's what I found during no start situation: Had fuel at cold start injector while cranking. Had spark at plugs Started checking resistances at AFM: E2-VS=255Ω (FSM says 200-600) E2-VC=250Ω (FSM says 200-400) E2-THA=.430 kΩ, ambient temp. 104° (FSM says 0.9-1.3...

Update: It's hot outside. I've taken it on several 50 mile+ trips, in the heat of the day and it has not repeated the problem I was having. The only thing that has changed since the last time it died id replacing the o2 sensors. Is it in anyway possible that my problem was caused by a bad o2 sensor?
