i am having some trouble with the oil pressure gauge, the gauge is working intermittently. When we connect using diagnostics tool it shows steady oil pressure from ththe computer. This is on a 2005 Sunsation with a 525efi. The gauge is analog. It works sometimes and as long as you don’t shut off the engine it will keep working, but sometimes when you re start the engine it does not work. We have checked the gauge wires. Anyone experience anything like this? Do you know if there is a separate analog interface on this motor, I cannot seem to find one.
