[QUOTE="TownsendsFJR1300, post: 1362632, member: 1003"] Sounds like the pump is only working /pressurizing at initial key on... Remove the air filter, put some fuel in a spray container and [B]spray just a LITTLE into the TB's to see if it'll keep running.[/B] If it keeps running, you know it's the fuel system. I suspect it is. When the fuel line is removed from the fuel pump, yes, the fitting should NOT leak. (a little from inside the hose will be present of course). I don't remember if there's a schrader valve on the injector side of the system. If so, monitor that and see what pressure your getting.(If any). As a side note, there was a large connector (maybe 8-10 wires-forgot), under the fuel tank that was prone to water intrusion. I had water intrusion as well, which caused crappy running issues. Once the connector was found and opened, it was quite corroded and green. Once cleaned out, dielectric grease applied, the issue was fixed. Worth looking at in any event.. [/QUOTE]
