I have a 1998 Suburban K1500 5.7 vortec. Starts and runs like a dream for 5 or 6 seconds then slowly sputters out. If I touch the throttle during the 6 seconds it immediately konks out.
If I unplug the maf and map sensors it will keep running, nice and smooth, respond to throttle etc. (default maps are running it?) so I don't think it is fuel pump pressure related or security related. I already replaced the maf sensor, no difference.
Anyone?
