OK Gentlemen. I've got an 87 300ZX NA Auto Trans THat hasn't been starting for about the last 3 weeks. it was running perfect for my dad parked it at a job he was working and it just didn't start after that. We tried reading damage codes for the issues and the first set i got was 11, 21, 41 i figured i'd be better off checking continuity and voltage between Coil and the distributor and i was getting low voltage from the coil but it was connecting and supposedly fire was getting threw. so i put in a new coil and tried it and it read a full 12 volts and worked ok but it didn't start now im only getting code 41 now and i need ideas immediately i'm beyond out i've heard the crank angle sensor on these things are notorious for taking a dump on you but this thing isn't even firing from the coil wire to the block when you hold it close so i don't know if my ECU is buggy or what so some good ideas would be appreciated thanks dudes laters

Did you read the Sticky by AsleepZ on the top of the Z31 forum? The answer is there.

Yea i checked it out but its still not firing up luck-a-ly we towed it back here so now i can work on it closer. i tried replacing hte ECU and it didn't fire so i'm wondering what else could be causing this anyone else had a thing like this?

So did you clean/replace your fuel temp sensor and check it's harness?
ok you talk about supposed fire getting thru. did you pull a plug wire and actually check for fire? if firing roll it over for 10-15 seconds then go stick your nose in the exhaust pipe smell like gas? if not no fuel (that is the easiest way i know to check for fuel on a no start). after that i would go for fuel filter/ fuel in tank?? if it was low and he parked on a steep incline...... fuel pressure (disconnect fuel filter under hood turn key on/ roll over be careful of possible fuel spray from disconnected line.

well its getting fuel i can smell that and its not sparking (or Arcing would be the better term) when i touch the plug wire to the block with a screwdriver in it. There's continuity in the lines themselves so there still good but theres no spark generated after the coil and no spark in the coil at all i'm wondering what else could prevent the coil from getting power is there a voltage regulator on that circuit or is it wired into the EXU or something its a pretty trippy situation lol. Thank you all for yor input by the way

The one that was kicking my ass , not sure of the name of it . But it's huge. Bolts right at the ass end of the transmission . i think it's the main ground . Also, Diz ground was loose.
Check those. Even now, i tighten the ground on my transmission once a month .
sorry i don't know the name for it.
Keep it simple always start at the basics. Have you checked your cap and rotor? is the ignition coil good? (pull coil wire hold near a ground point and have someone try to start) do you have a good connection from the ignition coil to your cap? how about the input to your coil good power there? i'll leave it there for now. remember start at the basics, while you are talking about grounds check the one to the ECU should be on or close to the battery, also clean your battery terminal if they are at all corroded and make sure good connection on all wires to battery.
