I just got a 1990 5.7 TBI running after 10 years of sitting inside. I did a rebuild of motor, cleaned gas tank, new pump and sending unit and new filter. Also new Coolant sensors, oil pressure sending unit. I put long tube headers on it, have it timed. The issue I seem to have is its running rich, loads up with gas and stalls out. Once I do have it running and throttle to higher RPMS, it seems to mellow out. But once I shut it off it wont restart as if its flooded. Leave it sit until drys out, fires right up. Any ideas where to start?
