Hey there! my name is ashley and i have 1986 nissan XE 720 z24. one day the tach, speedometer, and turning signals quit working. also something is draining the battery. the same day the electrical problems started it quit running. i can get it to turn over if i spray starter fluid in the carb. it will run for five or ten seconds before it dies. i replaced the fuel filter (which is recieving gas, i took it out to make sure), the spark plugs, and wires. when you turn the key over you can hear the fuel pump hum which leads me to believe its not the fuel pump but i don't know much about cars. i was thinking fuel pump, fuel pump relay, fuel line, or computer?? i have no clue where to begin and i'm lost on what to do next.any advice would be greatly appreciated! thanks so much! ---ashley

Hi Wendy. My name is Tim Dorton, I was a Nissan Senior Tech. The Frontier manual and auto transmissions are the same as far as the odometer is concerned. The computer uses the signal from the speed sensor to control the cruise control, speedometer, and determine mileage. Does the speedometer and cruise control work? If so the the problem is most likely in the guage cluster. Here is the wiring from the speed sensor.

I would say its probably a short or a ground problem at the turn switch or a wire in that area. you need a test light and probably a multi meater and some nohow a ground or wireing problem can even drive a master teck crasy.

Guys he has a Z24, Not KA24, Z24 for one, Is carbed and has older lifters and valves. They need to be tuned to spec within a certain specific limit and the cams must be rotated in certain positions when doing different valves, etc... Shouldnt take very long normally and its not a hard process but if you have a tick, you really should get it checked out. Btw, the Z24 engine's idle isnt controlled by ecu at all or else the carb wouldnt need an idle adjustment screw.

Try running a good fuel system cleaner through it. Sitting alot allows condensation to form in fuel tank. Also condensation forms on plugs, etc... Pill plugs and inspect, but do run system cleaner regularly.
