I bought a program PCM from our computer resources just received it in the mail installed it; now vehicle will not start. If I put the old PCM in the fires right up but with the new one it will not start and is supposedly programmed with the right VIN and all of that.

I am attaching the information about flashing this ECM. I would recommend you contact the company you bought it from and make sure it was not pre-programmed. Most of them that you buy online are already programmed. So if yours is then it is either the wrong software installed in it or the ECM could be defective. I would start with the info that the original ECM starts the vehicle and this one does not.

If it is not programmed then take a look at this info to get it flashed. You will need the capable scan tool or the CD option that it talks about.

Let us know what questions you have. Thanks
