I have reaplaced my in dash guages and my coolant temp sending unit and the guage still shows no sign of life. Now im about to change the fuel level sending unit. any help on why my guges are not working would be great!

Ok, I have the same problem--the temp guage just quit one day. Engine runs fine.
Its a 94 gmc jimmy, 4.3 w engine (has cpi). Its an automatic 4wd (4l60e tranny). I've changed the sender, traced the wire as far as the computer, but thats all. The dash is digital, everything else seems fine.
Can't seem to find a wiring diagram anywhere for the 93/94 versions.
