Nissan Repair: car get fuel and spark but does not start, fuel pressure gauge, mass airflow sensor

Question
I have a 1995 Nissan Altima and recently it started stalling and breaking down then starts back up again but now wont. I changed the fuel filter and the ignition coil. its getting spark and fuel but wont start.  do I need to test the pressure of the fuel because i think it might be the fuel pump or relay?  It turns over but will not start.
Thanks for your time

Answer
Trevor,

If the plugs are good and you are getting fuel and spark then I would be looking at the mass airflow sensor.  Get a Haynes Manual or a factory service manual for the readings.  If you have fuel pressure then you should not have a problem with the fuel pump or relay.  Get a fuel pressure gauge to check the pressure.
