Hope some can help! Daughter in-law has an 07 Acadia that will not start. Turns over slow but steady. New battery. Oper the air intact and there are small “burps” as turn it over. History of issue, she drove it to work, came out to go home. No turn over, no start. Had it towed to local mechanic and they said that they did not have necessary computer to check out. She then had it towed to dealership. They said it was a problem with the transmission and tried to sell her a new car that her than repair. She does not have any diagnostic paperwork for me to review. Had it towed to her home. Calls me. I replaced battery with new battery. Now turns over but no start. Opened air intake a filter and tried to start. Burps out the intake but will not catch and run. Any help would be greatly appreciated. Thank you in advance!!!!!
