Your sending unit, fuel pump, or fuel injectors are clogged. Most likely problem, fuel pump is shot, Required dropping of tank, removed sending unit and pump, replace pump, and put tank back up. (Fairly easy with a mechanically inclined family member). Second most likely, fuel injectors are clogged, buy some injector cleaner at family dollar and put into gas tank. If it's the sending unit, empty your savings. VERY EXPENSIVE TO BUY PART AND COST OF MECHANIC!!
