Nissan Repair: 1998 nissan altima gxe stalls when dead cold, nissan altima gxe, fuel pressure gauge


Question
I have a 1998 nissan altima 2.4l that stalls once or twice when dead cold but once it warms up it is fine.  I have replaced the iac motor asy and cleaned the throttle body completely.  The egr valve moves freely when vac is applied, maf meter is clean and appears to be operating properly.  I am lost, please help!

Answer
D. Carrico,

I would check the fuel pressure regulator and the fuel pressure to see if, once the car warms up, the fuel pressure is not sufficient to run the engine.  Get a fuel pressure gauge and see what is going on with the fuel pressure and email me back.
