Buckstopper Posted April 27, 2016 Share Posted April 27, 2016 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? Link to comment Share on other sites More sharing options...
wotdsm Posted April 27, 2016 Share Posted April 27, 2016 I'd pull codes and check for spark next and then report back 2 Link to comment Share on other sites More sharing options...
Buckstopper Posted April 27, 2016 Author Share Posted April 27, 2016 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. Link to comment Share on other sites More sharing options...
Buckstopper Posted April 27, 2016 Author Share Posted April 27, 2016 I also tried a different used coil to see if that was the problem but it did not start with that either. Link to comment Share on other sites More sharing options...
desertsubaru Posted April 27, 2016 Share Posted April 27, 2016 Check to see if you have power going into the coil. 1 Link to comment Share on other sites More sharing options...
Buckstopper Posted April 29, 2016 Author Share Posted April 29, 2016 No power to the coil. Link to comment Share on other sites More sharing options...
Numbchux Posted April 29, 2016 Share Posted April 29, 2016 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. 2 Link to comment Share on other sites More sharing options...
Buckstopper Posted April 29, 2016 Author Share Posted April 29, 2016 On the diagram on the cover, is it the one that reads 15 A UNIT IG 1? It is also colored yellow. Link to comment Share on other sites More sharing options...
Numbchux Posted April 29, 2016 Share Posted April 29, 2016 Here's the pinout from the wiring diagrams: Pins 1 and 2 are the fuse in question. Link to comment Share on other sites More sharing options...
