I noticed that most of the plugs on the joyners have a good seal on them, but there are some important ones without a rubber seal and I think that may be one of them. I also had a 1100 sand viper that we went to move yesterday and it was running and then died. Got to checking around because the fuel pump and the fan wouldnt come on when you turned on the ignition, found that the top half of fuse box didnt have juice and started pulling plugs and found one that one pin was bent by whoever put it together and wasnt in the splice for it, it was just touching the side and had got hot and melted the plastic just enough to loose connection.
Also on the trooper, had mine die the other day and wouldnt start, got to looking around and it didnt have any pressure at the regulator, pulled the line off and the pump was working fine, so I took the line that comes from the pump and put it on the return nipple, turned on the key for just a sec. and then hooked it back up and it was fine. Didnt know if anyone has had a problem with maybe a small piece of something getting into the reg and blocking it? It has worked fine every since then.
Sorry about getting off subject, You can buy dielectric grease at about any auto store around.
