Time to pull the harness

I think so too... but I have to work myself up to it... now I'm starting to feel my frustration level go high.

I just hate to undo all that careful installation job I did on the chamber and T-body!

I took the truck for very short test run, hoping by some miracle that the injector would miraculously start working!! ... sadly I had to park it back in the garage with it still running on 3 cylinders... AND on top of that.... crap... the gas gauge quit working!!!!!!!!!!!!!!!!

I have faint visions of a new Tacoma or Tundra in my future.

Question, did you purchase vehicle with bad motor, or where you driving this when motor went bad ?

The engine was OK when I bought the truck in 2006.  I blew the engine in January of 2013 when I ran it out coolant, not knowing the water pump failed.  There was no coolant leak the morning I took off for Tucson.  The water pump shaft seal must have had a catastrophic failure about 45 minutes down the freeway.  There was a noise but I thought it was the idler pulley.

Are you running platinums or coppers?

Swap the injector number 1 to injector number 3 or 4 to eliminate or isolate injector problem.
If nothing changes, swap injector plug 1 and 2 if possible.
If nothing changes between the injector swap, I would swap spark plugs between 2 cylinders and if nothing, then wires (would be an unlikely problem after all the spark tests you have made, but is quick and worth doing still to completely eliminate the spark plug or the wire as being the issue)

Don't remove the harness before you have isolated it to be the problem, you'll come out a better mecanic and knowing your truck even more once you've found and fixed the problem.

I had installed a new set of platinums when I first tried to fire the engine.  I replaced them with a new set of NGK OEM replacements.

Yeah, I understand the idea of swapping to test, but each time I swap, I will have to remove and re-install the chamber, throttle body, fuel rail, and 2 1/2 pages of parts, hose, and connectors!

If I am going to remove the chamber and t-body to get at the injectors, I will test them and the connectors and then, if necessary, open up the wire harness loom.

I suspect that the injector is plugged, partially plugged, or just not firing.

The spark plug is getting spark and there is sufficient cylinder compression to fire an adequate mixture.

Set the valve lash?  I used the FSM method, with a feeler gauge.

Yes, I have a green propane bottle and torch adapter.  Is your "trick" the one used for finding a vacuum leak?

Possible causes for Your Issue based on Your testing.
Flat cam (I hope its not and EB cam,  :shake:)
Valves on that cyl. Leaking or to tight.
Vacuum leak to that cyl. (To much air will also put out the fire)
Plugged intake port (a Rag  :qtip:)
Or a bad Injector (You can pick the reason)

Have You checked the resistance value of the injector? Easy test
If Your interested I can show You how to make a cheap tool that will allow you to run the engine off of propain for testing purposes. All you have to do is ask. It works great I do it all the time when Diaging a failed injector.

I suspect You bought an engine Builder cam Didn't You.
Try adjusting all the valves again making sure each valve is adjusted when you are on the back side of the cam lobe. This exact same thing happended to me and is why I will never use a crap EB cam again.
poor cam grind is likely your problem. If you adjust it on the back side of each lobe it will run on all 4 cyl.

It is funny you should mention the camshaft.. .because I didn't like the fact that the lobes seemed to be off from the rockers.  And for some reason I kept thinking this mis-fire had something to do with the head or the valves.... as I have mentioned. If it is a "defective" camshaft, I will be very surprised.  I would have to have a very serious conversation with Tod at engbldr.

Thank you for your input.

So I should rotate the crank pulley to each valve to be adjusted, then rotate the crank further so the rocker is sitting how far down on the back side, off the nose, of just number one cylinder?

I won't be able to re-adjust the valve lash until tomorrow afternoon.

Adjusting the valve lash on the back side of the lobe, which will be lower on the nose. That adjustment will effectively tighten the valve lash, which will push the intake valve open sooner and extend the top of the valve into the chamber.  I am concerned that it could push the valve into the top of the piston.

Before I do this, I will need to have a conversation a few people who are smarter than me.

Man oh man.
There is a peak to the lobe (the tallest part)
You should be adjusting each valve on the back side (the complete opposite of the peak)
This is how it's been done for years.

I'm hurt.
The cam grinds that I have received from EB have bin imprecise. The last engine I built for a customer 22re had a dead
Miss on cyl ? Hell I think it could have been #1
I found that if I readjusted the valves loose it would fire that cyl.
I put a dial indicator on the lobe and it would start to open a small amount then close then open again. This was caused by a horribly shaped lobe.
I love EB and have tremendous respect for what they do and the parts they sell.
I have two exceptions. The Cam shafts (poor quality) and the gaskets (especially the notebook paper thin timing cover gaskets)

I had installed a new set of platinums when I first tried to fire the engine.  I replaced them with a new set of NGK OEM replacements.

Yeah, I understand the idea of swapping to test, but each time I swap, I will have to remove and re-install the chamber, throttle body, fuel rail, and 2 1/2 pages of parts, hose, and connectors!

I suspect that the injector is plugged, partially plugged, or just not firing.

You should only have to remove the rad hose and possibly the t-stat housing to reach the #1 injector, you should then be able to test the wiring harness and the resistance of the injector w/o having to disassemble anything else.

Hey Snowtoy,

Yeah... I figured I could get to number #1 that way.

I appreciate the input.

... The cam grinds that I have received from EB have bin imprecise.

I have not visually looked at gobs of camshafts from different manufacturers so I don't have a big comparison.... but...

Again, when I first received the head with cam installed, I wasn't impressed with the "look" of the camshaft.  It looked like a rough casting.  The lobe surface seemed a little too rough. Then when I installed the rocker rack and saw how far off the rockers were laterally from the cam lobes, I was more concerned about the "quality" and preciseness.

I had a conversation with Tod at engbldr about it.

In my opinion, the head and camshaft in a 22 is one of the most important components for top performance and longevity.  Now at $5,000+ invested in this rebuild, several hundred dollars either way means diddly squat to me and the number hours invested.  I rebuilt this engine with the idea of not compromising on quality.

I could have just purchased the stage 2 head from 22RE Performance at a slightly higher price, but now wondering if that would have been the less risky choice.  I really like their detailed list of parts and assembly.

Hindsight can really change your perspective.

I'm tempted to get a degree wheel and mic the camshaft and see what it looks like in thousandths of an inch, and check the actual lift, duration, etc.

The valve lash spec by engbldr on this 261C cam is I=..007" - E=.009" - that is one of the tightest valve lash specs I've seen for a 22 cam.  Adjusting the valve lash loose should *effectively* reduce designed overlap at spec'd valve lash.  I'll try 9 and 11 this afternoon - after I do some testing on the injector connector.
