Unhappy 96 4runner 3.4 won't start

Ok I will start at what happen. Went out to start the 4runner and it would crank and fire and shut off. So thinking it might have flooded left it until the even and tried it again the same thing but getting worse as not firing at all. Shoot starting fluid in intake would fire then shut off. So replace the fuel pump and filter and now have fuel pressure, but still will not start. This is were I am stuck. I have fuel pressure, spark, and the timing is correct all marks line up. I do not have a compression check tool. There are no codes. Were do I go from here i'm lost at this point?

Thanks for any help.

Check your AFM. If the ECU doesn't get a signal that air is flowing it will not start.

How did you test it? Is it getting power? Try the igniter

I checked the AFM with ohm meter and plugged back in and tested the voltage when blown through. I will check the igniter.

With all this cranking and not starting have you pulled the plugs and cleaned or replaced them.

You are running the correct double electrode plugs??

Have your wires on correct ?

None of your connectors have bent pins??

All connectors were cleaned with contact cleaner.

These things corrode you can`t see it with the naked eye they will drive you crazy.

The readings with a meter are always good as well it is just when plugged together it does not work.

Yes I'm running the correct spark plugs. Wires are correct. No connectors have bent pins. The connections that i have taken apart have been cleaned with contact cleaner.
