2001 Pontiac Grand Prix ECM promblem

What was the code?Need to know before I can help.

The p0650 is an output driver fault within the pcm, an output driver is an internal ground inside the pcm. Before you replace the pcm check the MIL fuse first, it could be blown. If it isnt then you would be looking at a possible pcm problem, her is how it works, Output driver modules (ODMs) are used by the powertrain control module (PCM) to turn ON many of the current-driven devices that are needed to control various engine and transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which the PCM is commanding ON. Unlike the quad driver modules (QDMs) used in prior model years, ODMs have the capability of diagnosing each output circuit individually. DTC P0650 set indicates an improper voltage level on the output circuit that controls the malfunction indicator lamp (MIL).
Post back with what you find.

The the I/p ignition fuse is located in the fuse panel at the instrument panel on the side of the dash, and the ECM fuse is in the same location, just check to see if there blown. As far as the car starting that would be a different problem, check the fuel pressure, if you have to push the gas pedal to start it, thats more of a fuel issue. You can do this stuff on your own or take it to the dealer, the choice is yours, if you dont think this is something you can do than take it to the dealer.

I would also check for corrosion at the PCM harness at the PCM,here is where the pcm is,

the pcm is number 4. in all you will probably be replacing the pcm,if you do it needs to be programmed.sorry I wish I was in miami,im in NY.

Its just called an ECM, it costs about $400.00 for just the ecm, installed and programmed probably $500.00 to $600.00.
