:help:Just put a new 22re in my 86' 4runner and it won't start. It cranks and cranks but nothin. Checked compresion and spark. fuel gets atleast to the far side of the filter. I think the injectors aren't working for some reason. I don't think they are clogged cause it's all 4 and it doesn't even tray and start. Any help would be appreciated.

84runner · May 22, 2003, 07:49:42 AM

Well make sure its getting through the injectors,then chech your timming

4X4U · May 22, 2003, 02:29:45 PM

How do you check the injectors?

mhemingw7 · May 25, 2003, 10:15:45 AM

check the grounds
a comon problem with engine faults is poor grounds
check and make shure all of them are conected and in good shape especialy the body grounds

open up the thoudle blade and put in a squirt of starting fuild , see if it fires a bit if not its spark. :thumb:

Crack open the Cold start line on the cold start injector on the plenum, (about mid point on the plenum) use a 12mm box end, as soon as you break the nut loose it will piss gas out, if it does that you have pressure to the injectors. Then look down on the side of the plenum at the 6 bolts/nuts that attach it to the intake, then see if you hooked up those ground wires that are supposed to be attached to the plenum for ground.....thats where the last 3 installs messed up, easy enough to do, hook up and vrroom.
Or just check those grounds first before what I said abouve....hope thats it...

4X4U · May 27, 2003, 07:41:38 AM

Does anyone know how many grounds there are and also their locations?

5spd · May 27, 2003, 03:35:27 PM

There are at least 4 grounds, battery, back of block to fire wall, and the 2 that are grounded on the plenum about 1/2 way back, should be the 4th bolt back from the front (this is on the plenum, and on the pass side, , if you do not see any grounds hook there then they are just hanging loose) and the one on the drivers side to the engine mount. These ones here that I am pointing at have been the issue with some swaps, being disconnected, engine will turn over like it wants to fire up, but will not start.

4X4U · May 28, 2003, 03:36:21 PM

I've only got one on the plenum. I can't find any other grounds that would go on a bolt though. I do have one funny looking connector left that i can't figure out where it goes. it's got one flat brass connector in it that's about 1/2 in wide. any thoughts?

Where is it located? right, left, front, rear, by alt by starter? what is it hooked to..or harnessed to?

4X4U · May 29, 2003, 04:39:41 AM

Sorry i took some pix but i can't get the camera working. It's on the pass side and it comes out of the harness bundle with like the injector wires and and other sensor plugs.

4X4U · May 29, 2003, 07:13:24 AM

hey the other thing i need to know is on the injectors there are two wires. Does it matter if those wires are crossed? Could that cause the problems i'm having. I spliced in new connectors cuz my old ones were broken.

drybone · May 29, 2003, 09:04:26 AM

makes a big difference if the wires are crossed, especially if you have the voltage reducer next to your left side fuseblock by the battery. The other thing you might try, I'm not sure how long your injectors have sat around, is tapping them with a small hammer and an extension as your cranking the motor.. I bought a set of balanced and flowed injectors from D.O.A. racing, threw them in with a new motor and couldn't get it to start for nothing, I tore everything apart twice to see if I missed something. The truck got towed to a master yota mechanic, and he couldn't figure it out, finally I called Tim at D.O.A. and he said that sometimes the injectors go dormant (go figure) sure enough the motor started right up as we were tapping them. I wished to hell they let you know when you buy that stuff, would've saved alot of time and money. anyway, goodluck

4X4U · May 29, 2003, 12:26:50 PM

well i changed those inector wires around and i still got nothing.

4X4U · May 29, 2003, 12:27:40 PM

If nothing else does anyone know any good mechanics around the concord, ca area?

There is a connector that is not used on all motors, I have one where you speak of but its not connected to anything, just folded back and tied to the harness.

gferris5 · May 29, 2003, 06:48:14 PM

I had one of those too, but I put a piece of tape around it that said, "Nothing" man, I'm so glad I did that. I do have a stupid suggestion for you in the realm of fuel delivery: it might be your fuel pump, if you're really stumped, tap on the tank gently with a rubber mallet. It's unlikely, but you never know...

4X4U · May 30, 2003, 04:02:25 AM

thnks for the idea but i cracked open the cold start injector like 5spd said and sure enough it squirted gas in my face. I'm gonna tear into the intake today and clean up the injectors.

4X4U · May 30, 2003, 02:18:40 PM

finished pulling the injectors and sent them to rc engineering. They looked pretty bad. I noticed that the intake had fuel puddled in the bottom part. Is that normal for clogged injectors?

drybone · May 31, 2003, 10:07:01 AM

Even though Tim at D.O.A. stocks them: the injectors I'm talking about came from RC, don't forget to tap them as your cranking the motor.

4X4U · June 01, 2003, 04:09:10 PM

thnks

gferris5 · June 01, 2003, 06:30:03 PM

hey 4x4u I just took my intake apart today to send in my injectors also and I also had fuel puddled in the plenum on the rear most runners. I'm pretty sure that it's just a sign that these things needed to be taken care of, but I wouldn't mind hearing from some of the pros on it...

4X4U · June 02, 2003, 12:48:32 PM

well it's good to know i'm not the only one. Hopefully that doesn't mean were both screwed.

gferris5 · June 02, 2003, 07:20:38 PM

nah, I really don't think so, I mean, it could be a really bizarre fluid, like antifreeze, or oil or something like that. I'm thinking that once everything gets flowing in there any excess gas just gets sucked into the chamber-kinda like a carburetor come to think of it...

Paul_Elbisser · June 04, 2003, 03:44:34 PM

Sounds like the puddle is from the cold start injector.

Did you check if your getting spark? Also check theEFI fuse at the drivers kick panel.

A way to check the injectors is to take a long screwdriver as a stethescope. Put the handle on your ear, and the blade on the injector. You should hear them click when you have a friend turn the key. Don't get anything cought in the belts or fan when you do this.

vikingsven · June 04, 2003, 04:04:56 PM

I would start simple first. :scratch: As mentioned earlier, check all your fuses, wires, etc.
Your problem also sounds very characteristic of poor timing. Get a timing gun and check the timing on the crank pully as a friend turns the motor over. Make sure you are close to the factory specs (5-8 deg. I think).

You say this is a "new engine"? Did you get a complete new motor, rebuild and swap external parts, or a transplant from another rig??

If you are moving parts from one engine to another, make sure that you set the rotor in the distributor to the #1 cylinder at TDC of the compression stroke. :thumb: I made that mistake once and my tuck wouldn't start.

Also, if everything checks out, it can't hurt to hold the throttle wide open when you are starting. My truck is stubborn sometimes in the morning (probably due to crappy injectors

), but holding the throttle to the floor fires it right up.

Hope that sheds some light on things.
Good luck. :chug:

4X4U · June 06, 2003, 02:29:01 PM

I got my injecters back today and they look brand new. I'm gonna throw them in tommorow and hopefully i will get it to start.

4X4U · June 07, 2003, 11:36:54 AM

Just finished putting them in and apparently they were'nt the problem. Still has the same simptoms. I rechecked the fuses and i don't think it's the timing because i don't get so much as a sputter and i've tried moving my distributor around. still open to any suggestions

vikingsven · June 07, 2003, 03:17:24 PM

Ok Basics:
1) Spark. Make sure you have spark to each plug.
2) Fuel. Make sure you have air and gas to each cylinder
3) Compression: should be obvious.

These are the basic requirements for an engine to run.

What is you timing set at? Are you *positive* it is correct.

Are you sure your plug wires are in the right order??

Did you try leaving the distributor loose and moving it around while having a buddy crank it over?

Did you set it to fire on #1 at TDC compression??

Let me know.

4X4U · June 10, 2003, 07:25:46 PM

I started it today. Turnes out i had the time set at the right place but it turned as i pushed it in without me noticing. No it starts and will run but only if i hold the gas. If i so much as touch the gas the rpm's spike. even if i let go right away. I'm thinking maybe a loose vacuum line. Someone plz tell me that these aren't signs of a bad tps.
