Would the lack of ground no. 4 cause the injectors not to fire? I have no power going to my injectors and I am trying to figure out why. The truck is not at my house but I think I need to check that ground.

Kind of curious if my issue with my truck is related to the grounds.
When hooked up to battery in my truck the battery drops to 10v when the battery isnt hooked up it reads 12.5 volts. if i hook the leads straight to a battery into another vehicle the truck starts adn runs fine but it wont on its own battery. the battery is brand new and i teven swapped it with another brand new battery. any thoughts?

awesome thread, thank you to OP. can anyone tell me where , on the number one ground.
umm, the wire splits off, one end grounds under compressor, where does the other end go 'by the starter?"
help! thanks!

Wow, I never realized how ghetto the wiring in my truck really was... well maybe just a little. But I am going to redo all my grounds. Thanks for the clear pics OP!

I purchased a 91 22RE and though the check engine light never came on I decided to check to see if any codes had been thrown. I did a reset to clear any old codes being stored and drove it around to see what was current. Sure enough I had two codes being thrown. One of them was #43 = No starter signal to ECM.
I decided to check out all the power and ground wires first since they are normally obvious and low cost. Besides, there were a couple of connections the previous owner made that I didn't like the looks of.
I found ground strap #3 was broken in two pieces so I replaced that wire and reset the computer. It got rid of code #43 and the engine now turns over fewer times before it starts.
This thread has me thinking if the system was that dependent on that one wire perhaps there's another I'm missing. Guess I should investigate further.

i have a 1985 4runner and I don't have the #1 ground. My battery is just connected to the body with the negative terminal and then that has a wire that goes and bolt to the fender and then another wire that connects to the block.
Should I wire the negative terminal directly to the block? so confused

Just re-did all the grounds... all but #4. I can not find the 2 wires that are supposed to lead out of the wiring harness (seriously, I don't know how this truck has been running for so many years with this rats nest of a wiring job.) Does anyone know where those are supposed to connect to so I can bypass the wiring harness and just run a few new ground wires? My Haynes manual is back in Colorado.

Edit - It's actually the idle switch ground in the VAFM, not the actual volume signal ground.

Depending on the size of the cable the way it is hooked up is just fine.
Now if the cable is under sized Like These years were from new it could be a problem.
It does allow for another spot to corrode but nothing to get excited about as we have seen worse.
Wired like this is not my first choice and might have been done because the correct parts could not be had when needed then never fixed the correct way because it worked..
Not really all that different then running a ground distribution bar.

Seems not many take care of their tiny battery cables and grounds then wonder why they have problems.

This ground point is basically the star ground for several sensors. Knock sensor shield ties here, O2 sensor shield(s) as well as signal ground, VAFM ground, diag connector ground and then back to the ECM. I have no idea how you're not getting codes without this connection being made somewhere. Perhaps they just put it back on in a strange place?
Edit - It's actually the idle switch ground in the VAFM, not the actual volume signal ground.
If all those systems are tied to that ground, I would think they should have a common junction before it goes in to the harness and out to the ground point. Does anyone know where that junction is so I can put a new wire in?

I don't think that any of those systems are getting much of any signal right now... I hope it will start up once I find those wires and pin them to the ground.
