I have the 2.9l bronco 2 89 model we replaced the ignition module, fuel pump, plugs, wires, distributor cap, and rotor button, its starts up and idles fine but when you give it gas it starts skipping and has no power any ideas?
It could have a weak or failing ignition coil. The other thing I can think to look for would be an exhaust restriction.. (clogged catalytic converter)
What about the fuel filter?? was it replaced?
SOURCE: No power to fuel pump
Hi..my name is Keith..and the 2 things that i know of...that will not let power go to the fuel pump is 1..the fuel pump relay being bad..or 2..that something has tripped the Inertia Switch...and it needs resetting..i hope this will help
SOURCE: 1989 Bronco II have replaced fuel
Is it the 2.8? I am just thinking of what cycles and would cause the engine to run bad. The fuel relay would not be the problem. Because if it doesn't close, then the engine does not run at all. The power distribution box is a possibility. But I am thinking about what you are saying the problem cycles. That is the strange thing. I think that the cycling has to do with pressure in the fuel tank. Have you tried changing the gas cap? That could be all that the problem is. But it could also be the vent in the fuel tank. The reason why I am thinking this is because the fuel tank builds pressure from the gas sloshing around and when it builds up too much pressure then it relieves. What do you think?
