870 2006 fuel lift pump

[Lonestar10]

sounds like air in the system.. either keep rolling it with smalll short starts or let it snort some ether. if you can get it to run on 5-10 seconds of ether i would think that would be enough to purge any large amounts of air the and the small amounts left would just run a bit rough.

if you have insite try to get a visual on what the fuel pressure is when it catches and see if it falls off before or after it dies.
