1984 Nissan 300ZX - Answered Questions & Fixed issues
Accidentally shorted battery on installation in my 1984 300zx, all dash lights, interior lights, radio, heater and pop up headlights not working. Have checked all fuses on interior panel, they are all
Before we go under the hood---did you check the cables/wires leading to the fuse box---and to the appropriate fuses---to make sure they are attached, not corroded or frayed?
If so, carry on-----
There are two relay boxes attached to the fender under the hood on the passenger side---one in front of the shock housing and a narrower one beside the battery.
There should be a label and/or description on top of or under the lid indicating which relay covers what circuits or equipment. In your case, there may be more than one culprit----so check them all.
BEFORE OPENING ANY RELAY BOXES or PULLING ANY PARTS----Disconnect the negative cable from the battery and secure it so that it cannot ground out against and body or engine part.
To open the relay boxes,unhook the snap release tab on the side. DO NOT FORCE the tabs cuz they are easily broken and, if so, cannot be re-attached.
Pull each relay separately, check it then replace it before pulling the next one.
Note: You will have to pinch the snap 'release tab' (a bit of plastic not the same color as the relay itself) and probably have wiggle the relays a bit to get them out.
Check each relay thoroughly.
Even if they look 'whole', give the protruding wires a firm tug to make sure they are connected and haven't shorted out.
If good, replace each relay before pulling out the next one.
Once you find the culprit relay, take it with you when you go to the parts store so that they can match it exactly. Size and wire color matter.
Note: There is yet another relay box inside the car---attached to the firewall under the drivers side dashboard. Check those relays as well and make sure to wiggle the wires on each.
Note: In all cases, be sure to inspect the wires leading into and out of on the relay boxes themselves.
Look for corrosion (usually white powder), melted coverings and/or frayed wires. Replace as necessary
I repeat: There may be more than one broken/burnt circuit, relay or fuse so check them all.
Once remedied, re-connect the negative cable to the battery and tighten it well.
Turn your ignition key to 'Accessories' then back to 'Off' three or four times before actually starting the car---just to reset the computer(s) (if you have one) .
Let us know.

Runs rough after warm up
Areas to look: Coolant temperature could be bad, located to the driver's side of the engine below the thermostat. corrode connections can cause the problem. Corrosion at the connections where it plugs into the air mass sensor. It's hard to see, but is is not that uncommon. Make a small tool you can get into the harness connectors to scrape each plug and then scrape the pins coming out of the air mass. The air mass sensor it self could be going south, but usually they act up even cold' Those would be areas I would start looking. Good luck.

,y 84 nissan 30zx 2+2 is overheating.water pump
Was the thermostat bad. To check it,put it in pot of water and boil on stove and see if it opens at 180 degrees,if it doesn't then it's bad.Are you sure water pump is circulating,doesn't have to leak to be bad.Is your radiator flowing good,not clogged and do you have a blown head gasket,check oil to see if it is milky.Is white smoke coming out of exhaust pipe.Also how does your spark plugs look like,not oily,I hope.

Car stalls after starting
As with any no start issue, you will need to figure out if you are dealing with a no spark or no fuel problem to proceed.Check for spark at the plugs and fuel for the injectors next.Could be a relay or other electrical component.
