hi im new here. besides from that i have a 1990 300zx that won't start. its not getting any fuel to the spark plugs (and yes i checked the fuel pressure). i have pressure all the way to the injectors and something isn't obviously working. i think its the cas but im not going to change it unless it sounds like thats what the problem is. anyone who knows anything about these cars if you could help i would greatly appreciate it. thanks guys

 

Have you checked to make sure injectors are firing

 

check for ECU codes. a quick google search will show you how.

you need to figure out if you're getting spark. a google search will also tell you how to check for spark. then, like said above, see if your injectors are firing. you can test for power at the plugs (turning the car over and testing current with a multimeter), or take the cas off, plug it in, turn the ignition on, and turn the cas by hand, listening for injectors to fire.

the biggest thing is to confirm that it has spark.
