no start no crank

truck was running but battery's were original. removed the battery's and got two new ones and replaced. tried to start all lites lit up except wait to start (glow plug). truck would not crank checked the fuses they are all good inside truck and under the hood. checked the ignition switch circuits 12 volts and it is good all the way to the ecm. starter switch not picking to crank over. tried other switches and didn't do anything still no crank. removed the cover and pushed the relay in and truck cranked but didn't start leads me to think the ecm may be bad. can ecm lose programming if battery's are off to long. tried to look at other post but most don't finish posting after problem is fixed. any help would be appreciated. also can ecm be removed and flashed without truck.

Did you use proper procedure when changing your batteries?
Disconnect both negatives then both positives. When reconnecting, connect the positives first and then connect the negatives. That will prevent any short from arcing a hot positive to something else on the truck.

ECM without power is indefinite.
