22re rebuild

Ok so I picked it up and drive it home. Runs strong. Apparently my sped is off because my wife who was following me said I was hauling hinney the whole way home up and down the pass 10-15 over. 😎 Speed said I was at most 5 over.
So so according to my buddy is was a broken ground wire. I got lucky and blind stabbed the dristributor at 5 deg. TPS was perfect. They found and fixed the ground and she ran great. They advanced it to 9-10deg and she ran even better. So I am still getting a code but I haven't checked it yet. Probably O2 sensor. But it's home and runs strong. WINNING

Ok so I updated my build thread but that about as exciting as watching paint dry. So I will piggy back on this thread. I am getting codes 4, 5, 7,
O2 sensor is most likely a broken wire as it happened when I was installing my header. So I'm not overly concerned with that one.
My TPS code is probably from my damaged plug. I need to find a new or used one to splice on to my harness. Same with the water thermostat sensor. I believe this is a damaged plug or wire as well. In spring when the snow stops I came pop the hood and take a look. Or when I go up to the city this week where they call an inch of snow a lot.

The motor runs great but I am chasing a random ground problem (I think). Tripping lots of different codes and they are different every day. When she first starts up and I drive it I get what feels like an electrical cut out on occasion for like 5 minutes then it's done. Can drive it 100 miles after that. It trips codes but no cut out.
The codes are random like I said
3,5,7
3,6
4,5,7
10,13
3,4,5,6,7,10,13
6
5
5,10
Totally random so I believe it's a ground or my ecu is cooking. Yes those are codes for 8 days in a row. The current weather is snowy and cold teens and 20's with occasionally getting above freezing for a hot minute. She owns the snow for a stock rig. 18" of snow and never missed a beat. This is her parking spot
Yes I know that's not 18" of snow right there it's been driven on and packed down over and over again

Lookin' good! Did you get the code situation resolved?

Yea she starts and drives fine. But I have a few momentary cutouts that feel electrical to me. Most likely it is a ground. The initial No-Start issue was a broken ground. Then the start but no run was a ground as well. I have replaced the big major grounds but need to keep replacing the smaller ones. I guess I will know when I get it. All ready did the block to fender, head to firewall, battery to fender, and one other but it's to cold for me to want to go outside and look right now. 19 degrees out at the moment.

It looks like Toyota changed to the more rounded connector at the same time they switched to the straight intake and throttle body from 89-95. I never learned if the pins are the same on those, just stuck with what I had.
Also, if I had electrical gremlins like this, I'd probably suspect the ecu also. Have you tested it's pins with a meter?

I don't have my EWD handy but from memory E1 goes to the lower intake, E2 goes to the hot side of the head above the alternator. These are the primary grounds, with the battery ground connected at the intake support or directly to the block. I don't recall what all uses the cab ground but nothing jumps at me as engine critical.
Another cause for a random brown out, voltage drop, is the main EFI relay and fuse, check the voltage drop across both or swap in known good ones. Start with the fuse it can look fine but be partially blown.

Ok so I am more and more thinking this is a loose connection. When it's really cold below 20 drug she will fire and then die. Might get her to run for the day or might not. Sun hits her for about an hour or so she will start and behave with the few temporary cutout the trip codes but run great. Screams loose connection to me. As it gets warms stuff swells and it gets tighter.
Have I mentioned I hate being a mental midget.

Did you locate the loose connection? Curious as I am now diving into a 22re head gasket job that has turned into a timing chain replacement and rod bearing replacement. Also, do you have any recommendations for cleaning out the block after getting the rods back in? My block is still in the truck so my flexibility is limited. Thanks!

Haven't looked at it yet honestly. I am going to cave a bring it to an electrical savant I know. As to cleaning out the block I don't know. For coolant there is a drain I think on the drivers side that you can pull the plug. Maybe check the freeze plugs that you can access and see what the backside of those look like. If bad replace them. But for cleaning out coolant passages and stuff I am not sure. There are many people on here that may be able to help you more than I can. Try posting a new thread in the newbie section and asking.
Good luck. Hope this helps

Ok new symptom. Now when I shut it off after trying to start it the CEL and Charging light stay on but very very dim. I tried to get a picture but it had to be almost black outside for it to even kinda show up. The CEL is kind of visible in the top left of the pic. You have to zoom in and look really hard to see the charge light in the lower right corner.
Any ideas of where to look for this connection. I did not mess with any wires and only played in the engine compartment. All wiring work has been done to try and fix the problem and has been limited to grounds.

Charge gets a little complicated so, no offense, I'm hoping you find those two shorted together and lots of melted stuff in the dash harness..
Charge has power from IGN fuse on one side, then the diode, it joins the brake and at temp which both have diodes, and routes to the charge fuse and alternator L..
i do tend to over think stuff. Crappy contacts in the ignition switch. Some times they stick some times it's loose.. stuck partly you have power on IGN fuse, loose connection cuts ECU power
