Sorry Wayne, I needed an answer that night. Got it fixed about 3:30am that night. Going to request a refund. I had put on there that I needed an answer within an hour. That's why I didn't mind spending $65.00. Called and woke my diesel mechanic friend up. It was air in the injector line. Again had I known it was going to be 6-7hours for an answer I would have never continued. Figured someone was always on-line to answer questions. I'm sure your service and expertise are worth it. Was in a bad spot and had to get finished that night. Regards, Damon ******
