I have been unable to start my 97 formula 500 DLX for awhile. I just replaced the primer pump and now can start it with the primer. I also pulled the fuel pump and went through it. It looks fine to me but I ordered another one on amazon because they are like $35. However, it won't be delivered for 2 weeks. I'm wondering if the fuel pump can run if there is no fuel in the lines. Like I said I can start it with the primer and I thought this would trigger the fuel pump to pull the fuel into the lines but it's not working. I'm wondering if this is because the lines are empty and the pump can't function or if there is just a problem with the pump. I checked all the lines, etc and they seem to be functioning.
