92 ranger 2.3 to 2.3t swap, followed your wiring. Truck has spark and 38 psi fuel pressure at rail.Tried to start the other day, just cranks will not start. I haven't installed the vam, but it will not run in limp mode. Any help would be greatly appreciated,thanks.

Install VAM, report back.

If you say so...
From my experience (18 years or so with these engines), some run without the VAM, some don't. So I guess you can decide whether you trust my advice or would rather dispute my advice.
What I do know is that wasting time trying to figure out why an engine that's missing it's most important sensor (actually two sensors since the VAT is built into the VAM) won't run is always going to be a waste of time. First step in diagnosis is fixing known problems. In this case, the known problem is that the most important sensor is missing. So my advice is to install the VAM and figure out whether you have a real problem (still won't run) or not.

Installed vam that came from the same car as the engine. Still just cranks and won't start.

Does it have spark?
Does it have fuel pressure?
Are the injectors pulsing?
What are the codes?

Yes it does have spark and 28 psi at the rail. I do not know if injectors are pulsing, and I haven't tried to read the codes.

Check for injector pulse and scan codes. The codes will say if there are wiring issues, or if there is a sensor or ECU fault. EEC-IV Code readers are about $25, or you can use a paper clip and the check engine light and count the flashes.
Has the timing belt or distributor been loosened/moved since it last ran in the donor vehicle?

I puled the dizzy to put a new pick in but have put #1 on tdc and pulled the cap, button points to #1.

I pulled the following codes 58,65,66,81,82,84,85 from ecm.

You've got both VAF and VAT codes there (3 total codes) that all say the VAM is either faulty or mis-wired. Since it ran before, we can assume it's not faulty. The rest are typical "swap" codes.
I was going to link you to a site that has info regarding what the VAT and VAF signal should read but the site appears to be down at the moment so I can't find the exact link for that PDF file.

I have reduced the codes to 58,81,82,83,84,85,88. I can hear the injectors click on key cycle but not when cranking.

What did you do to get rid of the two 60's codes?
58: Vane Air Temperature (VAT) sensor out of range or open 88: Electronic Ignition - IDM, DPI or spout circuit fault
VAT is the air temp sensor inside of the VAM so it's still got a wiring issue, or is faulty. It's easy to tell if the reference site that's currently not working was available.
Code 88 should indicate a no spark condition, or at least a lack of timing advance (though advance doesn't kick in until it's running).
Sounds like you need to verify that injectors are pulsing while cranking.

I had pin 27 in 28,that took away the 60''s codes.
