Why wont my truck start. ( Its actually an 87)

Need to check for fuel pressure could be fuel pump has failed. First, check inertia switch (fuel cutoff switch) to make sure it did not trip. The switch is located passenger side under the carpet, under the dash and the toe-board to the right of the transmission hump. Turn vechicle off and press the button. Then cycle your vechicle ignition several times to repressurize the fuel system about 5 seconds each time. Then try to restart.
