Vehicle: 2001 Subaru Forester L 5 speed manual 
Old engine: ej251 2.5l sohc
Engine that was placed in: Ej25d from a 1999 Subaru Legacy outback (automatic trans), we took of the dohc heads and swapped on the old engines sohc heads
When we did the swap we swapped the heads, Intake manifold/intake manifold harness, used Ej25d headgaskets for the extra thickness needed but I did not swap out the crankshaft timing gear because it looked identical to the old engines one
I am having no check engine light (I’m guessing because the car hasn’t started)
Also not getting spark and fuel which usually means crankshaft position sensor or the camshaft position sensor or the crankshaft timing gear was not replaced from the original engine.
I am wondering if anyone can confirm that the 1999 Ej25d crankshaft timing sprocket is different then the ej251 crankshaft timing sprocket, I mean they look identical same amount of teeth on the back and everything, could it be that the Ej25d was an auto tranny? 
The car is cranking but will not start 
Any help or input would be amazing but I really need this running or I’m going to be forced to sell it and take a huge loss on money

The crank gear either has 6 teeth or like 32 teeth. There are only two types. So if it has 6 teeth it's correct. 

If you want to tow or trailer it to my shop in Milwaukie I can troublshoot your issue is 2 hours or less. Probably less.

This link shows it 'should' interchange: https://parts.subaru.com/p/Subaru__/SPROCKET-CRANKSHAFT/49224691/13021AA091.html

 

Did you check for a code? I don't recall if the CEL light stays on w/the Key ON/Engine Off, or goes off after a few seconds?

 

I'd suspect the CS sensor..should be easy to swap.

And Auto/Manual doesn't matter, AFAIK.

When I checked for a code, the code reader didn’t work it just said error 

The code reader works on another '96+ car correct? I had one that 'went bad' and thought it was the ECU, but was the code reader.

 

And this WAS a working car when you bought/got it? Just making sure you didn't buy someone else's 'project'. :-(

If you have no coms with the OBD-II port then that's where you start the diag. You check the 5v and the serial data connection back to the ECU - also ignition switched power and ground to the port. If that checks out and no shorts to ground, etc then you start checking powers and grounds to the ECU.

Did you turn the car on or at least to the start position before you plugged in the scanner?

Most will give a link error if this is not done,

 

O,
