Question about GMC C2500
How can i get my truck started, with another ecm, mine was rusted i had alot of problems,thanks
Hate to tell you this but they should have told you when you bought the ECM it would have to be programmed. Call your local dealer and talk to the service manager to see what all they have to do. Some vehicles when you get a new ECM you can program it on the bench and if they have the old one they may be able to get the parameters off of it. Different systems are set up different ways but most of the ones I have programed have been out of the vehicle on the bench. So he may tell you to just bring the ECM and maybe the old one also. I would get the VIN and the mileage also to take. Hope this helps.

I had the SAME thing with my car!! Remove your air bag module its a grayish looking box that deploys your air bags, my air bag light was on but it was on and off. I pumped gas in my car one night and when i went to crank it my car cut right off after a split second. My mechanic took time on it but discover that it was a secrity issue. He removed the air bag module and presto it fired right up. I thought it was a fuel filter or fuel pump. It was just the air bag module, people freaked out about it once i told them what it was....it should be under the passenger seat, i believe u may have to take out the seat to get to it.
