Nissan Repair: 1991 Nissan Fuel Problem, combustion fuel, pressure fuel

Question
I recently changed out 3 of my injectors - took them to NAPA and had all checked.  Did not replace the injector pump.

Replaced all parts and hoses.  Car will not start - no combustion.  When I put the clutch in, you can hear the fuel pump whine for a second or two and then stop (never did that before).  Tach moves slightly during turnover.  Distributor wire is OK.  There is spark.

After several attempts at turn over, I stop.  After a while I will try again, and I get a brief (1 second) of combustion.

Fuel is pumping, but I do not know pressure.

Fuel pump problem?  Especially now that there is a loud whine?  

Thanks, J.R.

Answer
JR,

Pull the fuel lines off the rail and get a coffee can and then have someone wiht a fire extinguisher at the ready and turn the key on to see what the volume of fuel is.  If there is no fuel then you need a pump.  If it does not fill the can in about 15 seconds then you need a pump.  Be sure to change the fuel filter first.
