1986 5.0 4 wheel drive Bronco

my son has a 86 bronco that will not start. he has spark at the plugs
but the fuel pumps will not pump any fuel, replaced both pumps, filters
and screen. Replaced ECU and the fuel pump relay. Firestone tested it
and said they think it is in the wiring. we have power from the ECU to
the rewlay and no power out of it...

Thanks for any suggestions..
down and out in Austin

you checked to see if the inertia switch tripped? Its purpose is to shut the
fuel pump off
in case of an accident. I believe yours is mounted in the kick panel area
passenger side. Has a large white button on the top, push it to reset.
