Nissan Repair: 1995 VILLAGER/QUEST, fuel pressure gauge, fuel pressure regulator

Question
Hi,
The Problem I'm Having With My 95' Villager Is 2 Things The

1st: Is When I First Start My Car In The Mornings I Have To Crank It About 5 Times Before It Starts, Seems Like If The Gas Is Not Getting Up In Time But I Do Hear The Fuel Pump And I Also Replaced The Fuel Filter...do You Think I Need To Replace The Fuel Pressure Regulator?...i Do Need Help With This Problem...


2nd: Is That When My Car Fully Warms Up It Starts Stuttering, Stalling, Spitting And Choking And Looses Power, When This Happens I Step On The Gas All The Way Down And The Car Has No Power/torque What So Ever. It Seems Like If Either It's Not Getting Enough Gas Or Like If It's Gasping For Air... My Van Has Only 98,000 Miles On It, I Did Change The Plugs, Air Filter, Pcv Valve And I Also Used A Throttle Boddy Cleaner And Still Nothing...can Someone Help Me Figure Out What Exactly Is Going On Here...  

Answer
Check to see that the car has fuel pressure by getting a fuel pressure gauge and screwing it into the schrader valve on the intake where the fuel lines connect to the injector manufold.  Your pressure should be something like 51 PSI.  If you are getting low pressure readings pull the vacuum line on the fuel pressure regulator.  The pressure should increase.  If it does not the regulator is defective.  The regulator is cheaper than the fuel pump and much easier to change.  Once the new regulator is installed check it again.  The pressure should increase when the vacuum line is removed.  If it still does not increase in pressure replace the pump and you will have the problem fixed.  A side line that I would check is the hose that comes from the fir meter to the throttle body.  This has to be in good condition with no air leaks as this will allow the car to have a hard start condition as well as the sputtering.
