Hey all. having a lot of trouble with my engine swapped runner. its an 87 dlx 22re 5 speed that p/o threw a "built" 22re from an 89 in. that said none of the fuel system has been working. I haven't gotten pump working and have tried everything online to get it running but ended up just hooking it to a dash switch. that said the injectors aren't getting power. I tried to get a reading at each connector and have no reading. I swapped it to 89 harness and ecu and it still doesn't work. im getting irritated and discouraged and need some help to get it running. any input helps. yes all grounds are attached that I know of. Thanks. -Kaleb.

The best advice I can think of is get a decent set of wiring schematics. The factory EWD manual is the best. Easy to read, breaks it down system by system, and shows connectors with wiring color.
Then get methodical. Just go through each system one by one. Don't rush and don't try and short cut the process. As you come across wires that have been repaired look the repair over., Don't assume the PO did it right. Ideally solder and shrink tube wires together. Make a connection you won't second guess later. the EWD manual will also gives you voltage readings you can check. The 1987 and 1989 22re had different injector systems and their injectors aren't interchangeable. you may need to confirm what the did there.
If there's aftermarket wires under the hood serving no purpose I'd remove them.
A lot of the electrical components will have part numbers. If you go to epc-data.com/Toyota you can see if that's for a 1987 or a 1989 4runner.
With fuel, spark, compression, and reasonably close timing you have internal combustion. Do you have spark?

Discombobulated

^^^^^Great Advice^^^^^

So you say the PO did the swap, was it running when you got it or did you take over the project??

This is one of those that’s impossible for anyone to just tell you what to do with so many variables, as said above I would start patiently digging in and post your findings little by little, lots of great guys on here that can help with the right info and the right questions!!!!

First, don't post a question and then disappear. Not if you want on-going help. Keep us engaged by responding.
I'll ask again. Do you have spark at the plug?
Do you know which injectors got installed?(1987 or 1989)
There's a ground strap that is bolted where the surge tank joins the intake manifold. On the 1987 this grounds the ECM. Is that one connected?(one of the easier ones to miss)

was not running and he just dropped motor on mounts and that was it. Ive spent months trying to figure this out and have had no such luck.

89 injectors. there's no power getting to them through the harness. the grounds are all installed and everything seems normal. I have spark and it runs find if I spray fluid in the throttle body. sorry for late response been a busy day.

1984-1987 22re takes the same injector.
1988 22re has it's own injector. I doubt it's much different than 84-87, but Toyota did list a different part number
1989 and newer is yet another injector. And this one is different than the previous ones.

Look at the picture below. Do you have that electrical component mounted on your right inner fender(resistor for injectors), and is it connected? If the answer is yes, and you're sure you have 1989 injectors, than you have a bit of a mish-mash to sort through. 1989 injectors didn't use that resistor.
I still strongly suggest getting a 1987 EWD manual off ebay or wherever. You'll need to decide which style EFI you want to have. My thought would be get 1987 injectors and call it a day. Just depends what parts you have installed, or what the PO gave you in a box.
It's going to take time. You gotta figure the PO hacked around for awhile before throwing in the towel, and I'm sure they created a mess.
I assure you, the one single thing my techs hated more than anything was picking up a job that's been half done by someone else. It rarely goes smoothly, and lots of head scratching wondering what in the hell the previous guy was thinking.

Yeah basically I have the resistor pack but its only connected to one of the plugs from what I recall. the other one doesn't exist as there's no plug on the 89 harness for resistor pack. I think it also goes to something else.

Jimkola

I'm getting the feeling that more things than just the engine are not for a 1987
Many things are different between the 1987 and 1989 trucks and 4runners, and they don't interchange. At least not without modification.

KalebEalahan04

yeah I have no idea that's my current issue. I have no idea where to look

Personally, if this was my project
1) Order the Factory EWD manual. Put fresh battery in my multi-meter.
2) while I'm waiting for EWD to arrive I'd reinstall the 1987 wiring harness and ecu.
3) install injectors for 1987 22re
4) remove any aftermarket components. Especially any alarms.
5)get under dash, especially on driver's side, and look for any wiring cut or repaired. Solder
6) by now manual has arrived. Sit down and go through each system. Start with ground chart. Then power source, etc etc.
Or
tow it to a shop. That will break the bank, though
or
sell it.
