Let Me Start This Off By Asking A Few Questions, Please.

Why did you replace the ECM (Engine Control Module) ?  
What was the original problem, specifically ?

Where did you get the ECM . . . new, salvage yard . . . did it have an identical part number or was it from a vehicle (same model-year, make, model) identically equipped ?

Did the car sit for a while ? How Long ?  
Did you disconnect the battery when you swapped modules ?

I’d first check the battery for being good and fully charged, with good cables and connections (all of them - both cables, both ends). Maybe the problem is just the battery power getting to the starter. Poor connections or a poor battery can cause the symptoms you are working with in this Tracker.

I know you didn’t ask for spelling advice, but I think the word you are looking for is “coming.” Let’s try to keep it clean! 😉

Hmmmm…Maybe we have found the source of the problem.  
Perhaps the ECM needs to have an “extraneous substance” cleaned off of it.

I have some ideals, just no ideas.
