I have a 1985 nissan 300zx------died at stop light and has not started since. I replaced coil,rotor,fuel filter. The pump is sending fuel to filter though. cranks but still wont start??

Remove rotor button and points are underneath. Usually capacitor is what fails and prevents starting. It is also located with the points. Replace both (cheap!) and adjust points and you may have a fix. If not, check are you getting fuel delivery? Do you have spark at the plugs?

Check wires for short to ground .

suspect 1) bad spark plug(s) - change whole set if needed, (2) failing ignition coil (3) failing
distributor component(s), or (4) worn out distributor cap and/or rotor - if these need to be changed,
change both the cap and rotor as a set.
COST: if yo do any of these repairs yourself, your parts costs would be fairly low, but getting a garage
to rebuild your distributor could be costly

For 1985 Nissan/Datsun 300ZX 3.0L FI 6cyl the Fuel Filter is located: Under hood, passenger side, side of strut tower, mounted in fuel line hose.

Hope this help (remember rated this post) TY for using Fixya.

Fuel pump sounds like the place to go.

check the timing belt see if it jumped time or broke you can also tell but pulling distributor cap and see if rotor turns when engine cranks!!!

WELL CAP & ROTOR WILL HELP ,WIRES,PLUGS,FUEL FILTER

Fuel delivery must be confirmed with a fuel pressure gauge on this vehicle. Disconnecting the fuel line and cranking the engine to see fuel shooting out does not confirm pressure, it only confirms fuel delivery. Remember you need both fuel delivery and pressure. On this vehicle if the psi is off by just one number that's enough to keep it from starting. Also replacing the coil and rotor (as you stated) does not confirm that spark is reaching the plugs. Confirm that both spark and adequate fuel pressure are reaching ALL the spark plugs.

Have the low idle sensor checked. That should be the solution.

alternator and mass air flow meter.
see my solution above.....
