I would start by actually diagnosing the problem.

An RE should fire in half a crank.  So while you are freakin' around for a "couple minutes"
Maybe see what is not happening.
Is the ecm actually turning on initially?
If it is, are you not getting spark? Fuel?




..... or just throw parts at it until something changes.

And vacuum lines..also air intake plastics for hairline cracks..

86 4R 22RE 4x4

The engine periodically surges under load and intermittently having a hard time starting it.  Battery and starter are fine just may take a couple minutes of trying to turn it over.

Have an engine code "6".

No engine revolution sensor (Ne) signal to ECU
- Ne being over 1000 RPM in spite of no Ne signal to ECU
- Defective Igniter circuit
- Defective Igniter
- Defective distributor
- Defective ECU

Code 6 point to the coil and ignitor.

Another symptom is an erratic fatory tachometer, as the tach. signal comes from the ignitor circuit.

Should I start with a new distributor then coil, igniter?

Why do I get a little annoyed when a new poster appears  in the forum and asks us to put on our pointy wizard hats and grab our magic wand and start pulling little white rabbits out of our butts. Then several members (they may actually be wizards) start throwing magic poo-poo against a wall to see what sticks.

What the hell does “periodically” “surges” and “intermittently” mean?

Periodically = every year, every month, every week, every other day?

Intermittently = every 3rd time the engine is started, at a cold start, a hot start?

Surges under load = while driving in 1st gear, while driving on freeway, while driving up a steep grade, while pulling a U-Haul, while driving over a big-a$$ rock?

The 22RE has critical inputs to the ECU, and some very expensive sensors.  Like deucie said - replacing parts to solve a mystery problem is like sniffing flowers through your butt.

What condition is this engine in?

When was the last time it was tuned?

Has anyone been messing with the engine?

How many miles on the engine?

What elevation in the vehicle driven?

What is the climate?

I have no magic and I'm short on little white rabbits, but here's a helpful hint:   Let’s define the problem, so we have something reasonable or logical to go on! 

That’s just my opinion – it may be worthless.

Sorry, I'm working 12-hour shifts and I'm feeling a tad crotchety this morning. 

Gnarls. 

Where's the "damn_cajun" 

It's been 5 days since the OP post.

Did you solve your mystery surge or do you still need some serious help?

I hope that COVID-19 is not factor!

dont know. maybe we didnt give him the info he wanted to hear. i thought it was a fuel issue could be electrical to. haha

I agree, my first thought was air/fuel mixture, fuel pressure, injectors.   Possibly a vacuum issue.

Yes all was resolved. After replacing the ignitor and distributor it cleared up. Don't know if it was one or the other or both but cheap enough to just replace them both.

Thanks
