Need some help no start 280zx
Ok..I have an 82 280zx non turbo...The car is getting plenty of fuel..But wont start...I replaced the wires..plugs..and rotor button..Still nothing..My father pulled the cap and stuck a screw driver from the center of the distributor and let it arc across the cap..and the car back fired..Put the cap back on..turned it over and checked for spark..It has spark..But it seems as if it sparks at the wrong time?..the car was running fine before..and now it wont even hit a lick..My father thinks maybe the IC module on the distributor is sending wrong signals to spark at the wrong time?

A car needs three things to run
-Air
-Fuel
-Spark
Since you're getting fuel, check the other two.
Since we don't have an OBDI-II connector, we have to do things the old school way
Did anything happen in the time it was working properly until now, when it is not working? Or all of a sudden, crank no-start?

well it was running like crap..I replaced the chts with a new one that i ordered from rockauto I just checked the timing on the cap with my chiltons manual that i ordered..all is correct..tried to start it again..nothing..but before all this..I removed a fuel injector to see if it was gummed up..it wasnt..so i put it back in..car ran terrible..so i called it a night..came back out the next day..fired it up..floored it and it wouldnt break 1200 rpms..then it would slowly fall down and die..Now it does nothing at all

ok now im down to no spark..I have power at the coil..and spark going out of the coil..But none out of the cap..What causes this..I am sure its the issue LOL..Im sorry for all the back and forth..I just need my baby running..Thanks for everyones time!

Yup..the dizzy spins..But no spark coming out of the dizzy itself..I DID notice that if i grab the rotor button and turn it a little bit..It clicks and the cap sparks..But when I put the cap on..pull the plugs..no spark..
#11
cap is new..rotor button is new..wires are new..Plugs are new..But im getting nothing out of the dizzy...like the distributor isn't telling it to spark..unless i grab the rotor button and click it side to side..THEN it sparks in the cap...

What sorts of witchcraft is this!

just to make sure wen u pull the plugs to check for spark u are grounding them right???
If im not mistaken the spark electricity goes from coil to the center of cap were the disrtibutor distributes it (if it spins then its doing its job) then from the rotor bach to the cap points then to the wires and thern spark plugs follow see how far it goes till it stops....check the conections from the spark plug wires maybe same thing happened to u like me and theplu was plugged in but the actial metal conection was pushed into the boot (no connection) heres the link to the factory service manual

280z backfiring issues need help
Okay I finally got my 82 280zx up and running..But now heres my problem..It idles kind of rough, It also backfires under load. I replaced my plugs wires dizzy cap rotor button coil. chts. and 2 injectors that i found leaking. now here is whats weird. number 6 cylinder. If i unplug that fuel injector no change. I also have another one doing it. I think number 2. If I pull the plug wires on them. No change. all the other injectors if i unplug make the car sputter and almost die. Why are these two causeing no change?

get a node light its a little connector that connects to the injector connector and has an LED that blinks every time the injector connector recieves a signal. that way you can wiggle the wire while checking the node to see if your connection is arcing or flat out disconnected.like 5 bucks for one at oriellys or follow fric frac ive done that, before i had the node light..

Just wanted to update everyone! My baby is back up and running. Turns out I had a serious timing problem. Also I had to removed all the injectors and clean them and rebuild. On top of that cleaning every electrical connection seemed to have done the trick!
