I have a vw polo on a 94 plate and i have a problem It wont start?

Iv'e checked the battery e.t.c and still no joy i have tried bump and jump starting so i think it could be the starter motor or the solamoid any one have any idea how much i should be paying to have this fixed (worst case scenario)I have a vw polo on a 94 plate and i have a problem It wont start?Check the connections on the starter motor and starter solenoid and the starter earth connection--edit- all connections are fine and battery is ok--then take a direct feed from a set of jumper leads connected to your battery--The,positive terminal of your jumper leads to the starter solenoid small terminal and bridge to starter motor heavy battery wire terminal and take the negative jumper lead terminal to an earth point on the starter or engine and the engine should turn over.You are effectively bench testing the starter motor on the car by doing this.If nothing happens then the starter motor is faulty.Before you do this check that your battery hasnt gone open circuit because if so it will drain the slave battery used for the jump starting.You can test the battery easy by load testing it with a proper meter which you dont have or--bridge the two terminals together for a second and if there is no flash or spark then your battery is flat,remove the battery from the car to do this because a spark can ignite petrol fumes that are present.This test is dangerous to do because a spark can cause the battery to explode if it comes into contact with battery acid fumes but i have done it many times without mishap.Better still buy a meter to test the circuits properly---edit again,if it wont bump start and the engine doesnt lock then it,s more than likely your battery is open circuit--sorry didnt read the question properly and didnt realise you had tried to bump start the carI have a vw polo on a 94 plate and i have a problem It wont start?If it won't bump start, then it won't be a faulty starter motor.

Does the starter motor turn when you turn the ignition key to the 'start' position? If it won't bump start and the battery's OK, it may be an immobiliser or fuel supply problem.
