99 tahoe 4x4 5.7. I just had this down at the shop to get a new transmission. While it was down there I asked that they try to figure out my starting issue I've had for over a year now. The issue is intermittent and doesn't come at any certain time. It can start for weeks on the first turn of the key, then just not start the next day. The fuel pump has been replaced, all fuses are good. The mechanics told me the spacer between the two connectors on the positive end of the battery wasn't allowing them to connect right. This seemed like bull because it was turning over, just not getting fuel. But when I picked it up yesterday, it started like a brand new car. Went out this morning, nothing. I do not hear the fuel pump turning on. What could this be?? What is connected to the fuel pump that can become disconnected. I made sure all connections were good last month when I put the new pump in. Thank for any help!
