how do i fix the tach, speedo and the oil pressure gauges in my 1988 s12, it has a vg30 in it

If all three aren't working I'd check for possibly a fuse for the gauge cluster or maybe check the cluster itself for some electrical issues.

If that's not the case then for the oil pressure gauge I'd check the oil pressure sensor.

For the tach, it gets its signal from basically the distributor so you may check the wiring around it.

For the speedo, if its electric just check the speed sensor and the wires and if its a cable you may just need a new cable.
