Once again my 3.0 wont start
#104
^^I think he was talking about the other post. So is it still not working? We actually found a 94 4runner same motor, same color, etc as our 92 for cheap money.... it was running before the guy took a few stupid parts off it, so we bought it.. wondering if the computers are the same, the wiring looks same, but not sure... we were thinking about just trying it to see what happens. I am so sick of this truck not running. I am going to steal some intertior parts from it anyway, and then part it out to some guys that need some stuff for Mud trucks. Curious to see how this all plays out.

well they arent positive that its the ECM now. and think its the wiring for the o2 sensor or something. its pissing me off though. I brought it to the dealership to have it fixed in a timely manner. Its going to be 3 weeks on saturday.

well today i went and talked to the actual mechanic working on it and apparently they had some other dude on it that gave up and said straight up that he couldnt fix it. Well now they have tho older more experienced guy on it and he said that it has everyone baffled and their "Toyota repair hotline" or something like that is also confused. He checked everything that there is to check, and has now moved on to wiring harnesses. He said the o2 sensor and wires are fine, and is contemplating taking the intake off to look at the main wiring harness and a few others. He noticed that i changed the head gasket, but i didnt tell him i did it. Said that wires could be pinched or something under there or they got hot and are screwed up. but needless to say I kinda got the point across that I need it back asap and that we werent fixing to wait a couple more weeks for it to be fixed. He is now gonna call my step father every time he does something or has news since im in school and cant answer. So hopefully this will be resolved soon.

Man... Well, at least we armchair diagnosticians who couldn't figure it out are feeling better if even the techs who have it in hand haven't been able to solve it. Shudder to think of the bill you'd get if they run a whole new harness though.

Awwww that stinks that they can't figure it out. We are going to take the entire intake off, and check our whole wiring harness, as we have been told by 5 different people that one ground in the wiring harness could be split etc... we are also changing the injectors as we have a new set with the 94 truck we bought and they are the same as what is in the 92. The ones that are in it are from an 88 and although they worked at first, they could be the problem.. so here we go again...

Its fixed!!! yeah thats what i was thinking. At least I feel better that it wasn't something easy to find. It ended up being that the white wire on the distributors wiring harness was broken, and wasn't getting a good connection at the distributor. Ended up being $550, which included a coolant temp sensor because the old one broke while taking it off. I wish they would have put the experienced guy on it in the first place. He had it fixed in a matter of days. And yeah i was thinking the same thing about a new harness. It wouldn't have been nice. And dave, your problem is probably the same or similar to mine. check all the wires from your distributor and o2 sensor, even the air flow meter. Try pushing them into the connector and wiggling the connector a bit on all the main components. And before you put those other injectors in I would send them off to WitchHunter performance to have them cleaned and rebuilt, they will also check the spray patter and all that good stuff.

That stinks.. We think we found our problem... our motor was out of a 88 pickup.. the injectors for the 88 are different than the 92, however, it doesn't make sense that it did run in the beginning after the switch of the motors... Going to put the correct injectors in and see what happens... Hope they find out what happened to yours. I am pissed that they did not tell me when they swapped the motors that the injectors would need to be switched, they changed the plugs on the wiring harness to accomodate the 88 and now I have to get plugs to accomodate the 92... fun fun fun! Good luck, hope you get it back soon.

The injectors aren't back yet, but I guess it is something to do with the older injectors didn;t have the same electrical?? so they tell the computer to shut off? I think its a shot in the dark, but willing to try anything. Is yours working yet?
#118
I should vet an answer on it today. The shop had to order a tool called an oscilloscope. To help figure it out. No more news yet though. Good luck with the injectors, and when are you supposed to get them back.
#119
Well the truck is running but he didnt do anything but re solder a connector. He is worried about the distributor, says that if you check the resistance that there is still something in them that can go bad. So if it breaks down again im just going to replace the distributor.
#120
ive been dealing with something similar, i just did the head gasket and now when i FIRST start the truck itll start fine but run a little rough cutting out here and there but not bog down.. then once you turn it off it will not start. then i found a leak in the intake hose which seems to be the main issue because the MAF has to have 100% vacuum seal to open that flap which turns on the fuel pump and creates the correct air/fuel ratio. im just going with the ISR mod tonight so ill post my results when i have them. hows ur truck been so far?
