This will be available from the Dealer or a wrecking yard, but I'm not sure you'll find one anywhere else. There are some companies that rebuild modules, try searching for these services online.

Its not ecm they're taking u for a ride. Replace the crankshaft position sensor
check the crank angle sensor,located next to the starter motor.get an ice cold can of coke,drive the car till it cuts out and pour the coke over the sensor...9 times out of 10 the car will start.this is a common problem...
