Default 98' Good fuel pressure, only runs with fuel to throttle body

I have replaced Fuel Pump, distributor cap and rotor, on my 98' fuel pressure tests 63 psi. It will start if I spray starting fluid in throttle body but will quit as soon as that runs out.
Could this be an issue with the Security system?

I've never heard of that. I wonder if there is an issue with your injectors?

The fuel system is not a fuel pump only. Fuel pump provides the coarse fuel pressure that gets from a:
tank->pump->filter->inlet-socket on plenum->fuel pressure regulator+injectors (aka spider)->fuel outlet socket on plenum->back to tank

The bold place is where You most probably do th test, but the fine fuel adjustment and injection to a combustion chambers is done in an underscored place.

Of course, that could be security (surveillance) system that shuts down the fuel injection, but more likely I'd point the spider.

Any background story ow how it happened?

Brgds, Mike
