2004 Yukon Guage problems

[jus10_99]

I haven't been able to locate a thread with my exact situation. My 04 Yukon has problems with the tach and speedo not registering correctly along with the fuel guage not working. "Stablity System Disabled" sometimes appears in the message center. I have a new fuel pump and sending unit in my tank since the pump went out about 6 months ago and I installed a new cluster two days ago. The problem is still occuring. Any ideas? Thank You

It sounds to me like you have an ignition relay or the ignition module itself that is going out, when this happens you can have all kinds of funky stuff begin to happen.
