whats wrong with my car?

[workinprogress]

It started a couple of months ago when my car was having trouble starting, then one day i was driving my 1993 nissan 240sx se hatchback when it started missing and backfiring then turned off for good, i have replaced the distributor, cap and rotor, mass air, plugs, wires, and tested both battery and starter. All it does is crank but wont turn over and i can smell the fuel going in. i truly have no idea what the problem is , any suggestions?

does it sound like its choking? pull you valve cover off and check your timing chain. KA's are known for eating them.

should be the second page down on that link or if you search nico theres a thread where "jyv" posted the picture to someone having a similar problem.

it most likely jumped a tooth or 2 if you checked everything else already and also check compression for good measure

If the timing chain did jump it is a "fix it now" problem not a "when you get the chance" problem

yea obviously my car wont even turn on anyway do the chain links need to line up like in the picture on the link set up by destroyyourmind?

[destroyyourmind]

the gears do I dont think it really matters where the chain but it does have a mark so dont take my word. it should say somewhere in that link I sent.

pull out a plug stick it back in the plug wire lay it agains the valve cover have someone else crank it over .. you shouid see spark .. if u dont start with a coil they tend to go bad when they are hott (when your driving ) .. they do exactly what u decribed when they go bad .. if the coil dosnt fix it try an ignition module ..

well the reman. distributor came with an ignition mod. so i dont think that was it but i will look into the coil. thank you for the suggestion.

that engine is a ka24de right? well i have a ka24e and it broke the key on the cam witch caused the gear to rotate on the shaft but not come off and everything still lined up for timing. it took a really long time for me to find it so u may try looking at this yourself. this is a not start issue right?

well i had my mechanic buddy from work take a look at it today and he said its definetly the timing, i had taken the ditributor out but i forgot to mark it(oops) so does anyone know how to line up a new disributor from scratch. i would really appreciate the help.

thank you for all of your help the car finally turned on and sounds just fine. after all said and done i believe the distributor went out but it was the timing and fuel that wouldnt let the car start. the fuel was bad, so i put fresh gas with sta-bil(additive) and the car turned right on afterwards. once again i thank you for your help.
