Hi,

The relearn is called a variation relearn. It does require a scan tool to activate the relearn. It won't reset by driving. See pic 1 below

As far as the injectors are concerned, each one has a gray wire to it. It supplies 12v with the one. Do they all have power? If not, there are two splices we need to check. If they do all have power, let me know which two injectors is not getting a ground pulse from the PCM.

Also, if only two cylinders are working, I'm surprised you were able to drive it.

Let me know.

All injectors have the same power and the same resistances according to multimeter. Also, when swapping injectors, the two that did not spray, now work. Looking at the engine from front bumper, the two injectors closest to driver side do not spray. But swapping they spray in the left side. And with all four injectors spraying they all work themselves.

I have replaced so many parts by now with everything else working well. I guess somehow, it's enough to start and run roughly and weakly with mass fuel consumption too. About half a tank every thirty miles.

Hi,

Wow! That's a lot of fuel. So, the two will not function but do have power to them. That indicates either the wiring between the injectors and the PCM are not making contact or the PCM is bad.

Have you checked them? Have you checked the connector for corrosion or any type of damage?

Let me know.
