22RTE won't idle after rebuild

GONOVRIT · Dec 14, 2013

I rebuilt a 22RTE and put it in my tube chassis rockcrawler. Got around to firing it up today and it will not idle. It will start when given some gas but will die after a couple seconds if the gas isn't applied in a feathering method. It is running rough when it is running.

I have no way of being sure if it is an 86 or 87. It will run at a high idle if the afm is unplugged. I have swapped ecm's, and afm's with no luck.

I guess it would help if I knew what all was required for the engine to run? This harness was cut and trimmed up while it was in the truck and was running fine before I pulled it. Everything seems to be hooked up and hot as it should be. It is now running mechanical gauges.

I'm out of ideas. I'm thinking/crossing my fingers this is something simple, any help or suggestions would be appreciated.

Here is the bare bones wiring for a 22RE... see if it helps you.

Is stock gauges still there ? It needs a temp sensor for computer but I can't renember if that designated sensor or was coupled with temp sensor also make sure knock sensor is hooked up... They go retarded without them

I have also found on quite a few yota builds that when the fuel system is opened up and left open for week or 2 or more for some reason they start suckin air around injector seals ...I have replaced injector seals on almost every yota I hsve built directly after leaving fuel system unhooked... Maybe they dry out or something? Idk hope it helps

Thanks, stock gauges are gone, I believe the temp sensor is the one in the t-stat housing and its still there. Into day two of head scratching

Turbos hate air leaks, both pre and post turbo.... My GN will not idle if it gets a leak bad enough on either side...

Have you checked your tps? If I'm not mistaken they are adjustable and if bad or not adjusted could cause that.

Haven't touched the tps,really don't want to since it was running fine before it was rebuilt.

I guess it would've helped if one of us finished installing the boost gauge. BIG vacuum leak. Its alive and well now!

Hahaha thanks but no thanks. I have two in my shop, neat engines. One of them is running a supra turbo and afm. That will make its way to my buggy eventually.
