Question about Mitsubishi Galant
If you are certain you are getting full pressure to the rail, then the ecm is not opening the injectors.
Just for verification, place a noid light on one of the injector connectors and verify that it is not being fired.
The next step would be to check both your crank and cam position sensors for signal. You will need an oscillioscope to do this.
If the cam sensor is not giving you a reliable waveform, your ecm will not know the engine position and it will not start. If your crank position sensor is not giving you a reliable waveform, the ecm does not know the car is cranking and you will not receive fuel, and it will not start.
If the noid light is firing, and in turn your waveforms are normal, look into possible bad gas or stuck shut injectors.

I agree with your approach that there is a problem with fuel.The fuel only comes out of the injectors it it is opened by an injector module. You can see a fuel injector has an electrical connector on the side. Need to check if Fuel injectors Module works. You can by NOID to check at any auto store, They are not expensive. When you hook up each one to the incoming connectors and start it will flash indicating there is a signal going to injector then the injector module is OK. If the injector module is OK then there is not enough pressure in fuel line to shoot out the fuel, then you need to look at Fuel filter and Fuel accumulator. When you first turn the key on the pump runs only a few seconds to prime then shut off, it is normal. When your key in ignition position, it will continue to pump. Then when you let the key off the ignition position will will continue to pump, but if the engine is not firing, then it will shut off a few seconds later. Here is the site selling the NOID so you know how it looks like, but you should buy from a store to address problem fast. Good luck. http://www.toolmancentral.com/Fuel_System_Accessories-c1339-pg4504.htm
