Outback 2.5 non turbo cranks but will not start

[Buckstopper]

Howdy Subie fans.  I have recently acquired a 2006 Outback.  2.5 no turbo.  AWD.  The previous owner replaced a dead battery and reversed the polarity with the cables to the wrong connectors.  Positive to negative and vise versa.  At this point, I have found that the main 120 volt fuse for the main fuse panel was blown, and the TCM (Transmission Control Module) is burnt.  I replaced the fuse and the engine would then crank but not start.  Then I replaced (with a used part) the TCM.  Still no start.  I checked to find spark at teh coil but found none.  Fuel pump primes with ignition on.  All lights on dash come on with ignition on.  Unit will crank strong for a while but no start.   Side note.... the ECM looks brand new and smeels not burnt at all.

 

Where do I go from here?

I'd pull codes and check for spark next and then report back

The hard codes ( before crank / start up) are 700, 743, 753 all dealing with tranny problems.  I actually have not checked the codes again with the new TCM as the engine does not crank continuously with the new used TCM plugged in.

I also tried a different used coil to see if that was the problem but it did not start with that either.

Check to see if you have power going into the coil.

No power to the coil.

Ignition coil has it's own 15A fuse on the relay block under the dash on the driver's side. Check those fuses, and check for power to them (although it gets power from the main relay, which is fairly safe to assume is good if the fuel pump is priming.

On the diagram on the cover, is it the one that reads 15 A  UNIT IG 1?  It is also colored yellow.

Here's the pinout from the wiring diagrams:

 

Pins 1 and 2 are the fuse in question.
