1989 Honda Civic engine start problem (very strange)

Hey guys!
I have an 1989 Honda Civic with 1.5l dual point injection engine.
I noticed that my mileage per gallon is low, but i did nothing about it, because the engine was running REALLY good! 
After a couple of weeks, i poured in some fuel in a gas station (the fuel tank was almost empty). I drove just half of a mile from the gas station and it suddenly lost all power and died after a few minutes of rough working. Now it won't start.
If i spray some fuel with a syringe directly into the intake manifol, the engine starts and works for a few seconds untill the sprayed-in fuel is over. The strange thing is that the fuel pressure is good and the fuel injector is spraying fuel. (injector is new)
Can it be bad fuel or maybe one of the engine sensors? (the ECU light doesn't show any engine problems) I think that the poor gas mileage is a different problem.
Maybe you guys have any idea what the problem is?
The car is old, but i LOVE it so i'm gonna do anything to get it started!
Thanks in advance
P.S. excuse me for my poor English, hope you'll understand what i mean

It's pretty rare but that sounds exactly like bad gas. Tough to tell but if you put in a new fuel filter and it behave for a while that would about prove it.
A suggestions for readers: Don't buy gas while the station is getting gas. There is crud at the bottom of their tanks that is normal and when all stirred up you can get that. The owner of the gas station was deliquent at checking the stations tanks and it showed up with cars that didn't make it far from getting gas - I worked there and trust me we don't and I know of none who purposely add water but it does occur by condensation and it simply gets pumped out periodically, T

That's what i thought later too!
I emptied the fuel tank and poured a couple of gallons on new gas.
Still won't start...

It can take a few tries after the engine thinks it's out of fuel to purge out air. You still need to try a new fuel filter which makes more air. Just go easy on the starter motor or you could add that to the problem, T

When you said the fuel pressure was good, did you check it with a guage or are you assuming because you saw fuel coming out of the injector? Your engine needs about 35 psi of fuel at the injector to run. Hook up a fuel pressure guage and let us know. Check it Key On Engine Off, then Engine Running.

Actually i just saw the injector spraying fuel, that's why i assumed the pressure was good.
I made one test - make the fuel pump work for 10 seconds non stop and measure the amount of fuel coming out of the return hose.
There supposed to be ~230 cubic centimeters, but i got just around 50-60.
So i'll just replace the fuel filter and then the fuel pump if necessary.
It's harder to find time for that because i just bought 1996 Civic S4 VTi. It's AWESOME
Thanks for your help guys!

When you go to replace the fuel pump, pull out the rear seats. There should be an access plate that you unbolt and the fuel pump module is just below that. I'm pretty sure that applies to your car. Check for that first, it sure beats dropping the tank.
