Car won't stay running

[ucantstopthebick]

I just posted one in the 240sx technical section but i figure that it'll do better over here...so i have 1992 240sx with the ka24de in it. it will start up like normal right away, and it will idle at about 900 rpms for about 5 seconds then it will just drop and die. if i unplug my maf it will stay running at about 1000 rpms...i switched out another good maf and it does the same thing...i dont' know what to start checking its weird and i'm not throwing any codes. it has a new fuel filter, plugs wires cap are all good...i'm going to check the fuel pump and fpr but anyone have an ideas? thanks
