I can't say for certain in your case but when I had the same problem with my truck the fuel pump in the gas tank wasn't working. Fortunately for me it was a fuse and not the pump. You should check for a fuel pump fuse and replace it if defective. Also you can remove the gas cap and listen while another person switches the key on to hear if the pump is working. If the pump is good and the fuse is good see if you can blow out whatever is blocking the fuel line. Hope this helps. Ralph
