Firstly check you have enough fuel in the tank to reach fuel pick up/filter. Make sure filter is clean and not retricting flow. Check that there are no splits or cracks in any of the fuel lines os primer bulb itself & that no pipes have become detatched all preventing the primer bulb from making a vacumn to drawfuel through. If non of these are the problem then the next step is to strip down the fuel system to check pipes etc for blockages.
