I have a 2003 LB7 2500HD, I replaced both heads, one was clearly leaking coolant into the cylinders. I just got it back together this weekend and now I'm having a strange issue.
Truck starts up better than before but sometimes the cluster guages do not work. It still shows the odometer and P R N D and any lights, they work just fine just the actual dial guages stay at the bottom. If I restart the truck a few times they will kick back on.
When I try to read the codes, most of the time my scanner will tell me there is like 58 codes set off but it wont let me read them. Sometimes it does let me read the codes, but only when the guages are working and its only 1 code for the Baro Pressure Sensor (I missplaced the sensor while doing the heads)
I did move my batteries under the cab by the passenger door, so I am going to double check my grounds this weekend but it does seem strange to me that it would start up and periodically everything would work fine with a bad ground.
Is there anything else I should be looking for to try to fix this?
