I have a 99 s10 Blazer, 4.3L, 80K miles. Last week the fuel gauge failed, the battery indicator came on, the temp gauge failed, and the light that indicates the gear your in went off. The low fuel light is also on. I check all the fuses - OK. I began to research this and found a TSB #3777 shows this issue. I can't find anywhere I can print this TSB. Has anyone run into this. How did you fix it?

Thanks

I have the same issue with fuel lite, gauge and check engine lite. Someone out there must have the clues to fix this.

I've done the fuses, replaced the fuel sender. There seems to be a break in the wiring somewhere.

As an aside, I just finished replacing the intake gaskets. Is there anything on the engine that would be a possible cause?
