  1. is there gas in the tank?


  2. is there power at the pump? if so can you "hear the pump" if it is mounted in tank.If the pump is pumping there could be an issue with the plumbing where the pump is pumping and the fuel is not being delivered to the lines and is simply being circulated in the tank. remove the pump again and ensure the lines are connected properly and there is no blockage and there are no kinks in any lines, make sure the fuel filter is not installed backwards as well, which is a common error.

  3. a fuel pump inline filter or shut off switch above brake pedal could be  culprits good luck

  4. I was going to say the same thing that Bob b said. Iwas thinking maybe the fuel shut out switch was'nt all the way in. it's going to behind one of the kick panels ,when you find it make sure that the RED button is push down .When you turn the key on do you hear the pump come on, if so,  then where you take the fuel filter out , is there some gas for a few seconds .if so , that all you will get until it is hooked back up , if your getting any gas at the fuel filter when you turn on the key that's all your going to get. .The pump want keep pumping fuel until it is hooked back up.The pump is not made to pump when the line's are unhooked
