Also check if there is a non-return valve fitted in supply line - normally located under van in supply line next to a anchor point - My old Jayco actually fitted it under a saddle clamp (which crushed the small plastic valve housing) only cost about $8 for a replacement - only a push on fitting with small ring clip each end.

Just had to replace my 3 1/2 year old Fiamma Aqua 8 pump with a Sureflow because it had similar symptoms. It seems to be the piston heads were slightly frayed at the edges allowing the pressure to leak back and making it run continuously, it would eventually restart after a couple of minutes of popping and spluttering. Moral, get a new pump about $110 on the internet.
