2000 Neon PCM replace, need flashed?
I picked up a PCM from the junk yard and the full pump turns on but it doesnt crank.
Does the PCM need to be flashed?
My key is NOT chipped either. The part number on the PCM is identical my PCM. The only difference is the vin number (obviously) and the module s/n
Is there any real way to check if the PCM is bad?
Noone has responded to my other post so I figured I would try swaping out parts and maybe fix it, luckly the junk yard will let me return the PCM.

If you have a grey, chipped key, the PCM needs to be flashed. The black keys are just a basic $1.00 key from the hardware store.
This is the only thing I found for testing the PCM. It's from the 2003-2005 shop manual, but it doesn't seem like there is anything specific to those years.

NO RESPONSE FROM PCM WITH A NO START CONDITION
POSSIBLE CAUSES
PCM FUSED B+ CIRCUIT
PCM FUSED IGNITION SWITCH OUTPUT CIRCUIT
PCM GROUND CIRCUITS
PCM
TEST ACTION APPLICABILITY
1. NOTE: The DRBIIIt and cable must be operating properly for the results of this test to be valid.
NOTE: Ensure the ignition switch was on when trying to communicate with the PCM.
Turn the ignition off.
Disconnect the PCM harness connector.
Using a 12-volt test light connected to ground, probe the PCM Fused B+ circuit in the
PCM harness connector.
Does the test light illuminate brightly?
Yes ! Go To 2
No ! Repair the Fused B+ circuit.
2. Turn the ignition off.
Disconnect the PCM harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground, probe the PCM Fused Ignition Switch
Output circuit in the PCM harness connector.
Does the test light illuminate brightly?
Yes ! Go To 3
No ! Repair the Ignition Switch Output circuit
3. Turn the ignition off.
Disconnect the PCM harness connector.
Using a 12-volt test light connected to battery voltage, probe all the PCM ground
circuits in the PCM harness connector.
Does the test light illuminate brightly?
Yes ! Go To 4
No ! Repair the PCM ground circuits.
4. If there is no possible causes remaining, view repair.
Repair
Replace and program the Powertrain Control Module in accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
