ECU Issues

[csipesri]

Help,
2012 GTX limited winterized by dealer and battery removed for storage. Left on trickle charge for winter as normal. When I went to connect in Spring, small spark when connected as normal but nothing when red button pressed. Sent ECU for testing and it was fried. Got replacement ECU, New 30A relay and New voltage regulator. Exact same issue. Connected battery, ( yes its connected the right way!) and same issue small spark when connected but nothing after that. Sending ECU for test again. This is getting expensive!

Any clues?

Did you test the battery? Maybe look for wiring shorts or bad grounds, usually when the ecu blows like that its because the battery was hooked up wrong, or there is an connection issue.

Yeah, Thx. Battery is good and hooked up correctly. If I jump the starter solenoid she cranks fine.
