s14 ka24de wont start

[kouki.monster]

i have a 1998 240sx se with a stock ka24de. i drove to work and everything was fine, then when i went to go home it wouldnt start. it cranks over fine. all fuses are fine. all relays are fine. jump start didnt work.

i later tried to figure this shit out after i towed her home and found out she had no spark in any of the cylinders. also the fuel pump wouldnt prime so im assuming the motor isnt getting fuel either.

i just had an aftermarket alarm installed and im wondering if that might be messing with anything.

any help or suggestions would be much appreciated!

I'd suspect the alarm first. It's really hard to help people diagnose electrical systems when they have a after-market alarm and all sorts of splices in the system.

I just put the alarm in valet mode it had no effect, and when I disabled it it had no effect either
