Want this question answered?
Do you mean an oil pressure gauge? Not tach?
Why?
If the speedometer and tachometer are not working in a 1994 Nissan Kingcab 4X4 V6, it could be that a fuse is burned out. It could also be that their mechanisms in the undercarriage are corroded or dirty if the vehicle was used for 4-wheeling off road.
Yes
That means that the bearings of the mechanism have failed. It is not economically practical to repair the tach. You'll need to replace it.
A cog and gear attached to the transmission which turns a worm driver attached to the tach
The Avenger did not exist as a 1994 model.
Yes, i found the answer. Truck had an aftermarket tachometer installed. 2nd truck this tach has been on. After 320,000 mi. on this tach, something in the wiring or internals failed. Unplugged the tach, truck fired right up. Check those aftermarket accessories you installed, before finding fault with the factory stock vehicle.
You will have to find the coil first.
on my tach, the green wire connects to the neg on the ign coil pack
Terminal number 36 in ur engine computer
sounds like a dead short in the tach wire, trace the tach wire and see if it the wire insulation has been broken.
