1993 240sx recent things done: -fuel filer, -plugs -wires/cap/rotor are new-ish. Car will start fine when its cold, but once in a while it will just crank if it is warm. Any Ideas? ---

idle air control sounds like it may be sticky. does it run fine after u have the no start problem? ---

if not consistant might be a bad coil, or like he said IACV. mine is the opposite won’t start cold runs fine warm, Just clean the IACV and put it back on. ---

Yea the coil makes sense. I forget, does the intake have to come off to get to the IACV? ---

He got a new coil from nissan, didnt change anything… Maybe MAF? I am pretty sure it has to be electrical. ignition module? a relay? ---

dont be tricked. make sure its the 2 wire one. the one wire sensor is just for the gauge. i belive they are like 20 bucks. it is the one wit the red clip on the t/stat housing
