2003 Seat alambra tdi 1.9 7sitzer und einen VW ...

I sell my car a SEAT Alam diesel with seven seats. Motor gear runs perfectly. I also have a Sharan of seven seats. He doesn't start right now. I want 800 for both. The SEAT is a very good condition. Motor transmission runs perfectly the other also runs motor and gear. I guess there's something with the pump that's why he doesn't start. He wants to start but unfortunately it doesn't work exactly. Damage I can't say what the VW Sharan has happened at once.
