Question about 1986 Ford Bronco
My old truck won't start . It's has 40 lbs of pressure at fuel rail and 36 psi when it does start . I can get it to run for about 30 seconds until it shuts off . I've already replaced both ignition switches along with the MAP sensor . It is a very basic fuel injection system but I can't figure it out . Any ideas would be great help .
Check injector pulse width first, might have a defective injector.
could also be the EEC-IV, this is the computer that controls the delivery side of the fuel system.
but first like slappy said try the relay just because of simplicity and access.
