Are you sure the aftermarket security is turning and enabling the ignition system? Did the car run before your rebuild started.
No the car didn't I got it off a mate and rebuilt it

Do you have the original loom with ALDL-any ALDL codes? You have oil pressure- low oil pressure will lock the ignition out.

Did it actually run & drive before you had or new build?
Fault codes?
Checked signal at injectors with noid light?
Battery voltage at coil & injectors?

Is new dissy vn/p or vr/s?
Different plug shape to harness...on dissy they used to be blue for vn/p & black for vr/s then later aftermarket were all black & sold as fitting all models when they didn't make proper contact due to different plug shapes.

Also most aftermarket brand electrical parts basically junk compared to factory stuff.

Does it actually work?

That is what other checks are for to narrow issue down....

Again, are you getting fuel out of the injectors? Not just at the rails, but actually into the cylinder? Can you hear the fuel pump priming to begin with? If it's not injecting fuel either then that also tells a few things.

from my limited experience if your parts are new and after market you cant assume they're OK .......with electrical problems its a process of elimination. also you could be chasing your tail until you do a diagnostic test........nice you tube vid on exactly what your troubleshooting, 1, 2 and 3
