the bronco needs to have the ground wire connected from the battery to the body. if you replaced the battery and disconnected that ground it simply won't start.
battery hooked up backward, wires crossed somewhere or it could be the solenoid.
it could be the control module
There is the FULL SIZE BRONCO and then the Bronco II ( the Bronco II is smaller , eventually replaced by the Ford Explorer)
I would suspect the ignition module. It is attached to the distributor with 2 screws.
Replace the pick up coil it's inside the distributor. This may fix it.
What is inside a battery ? Rocky_B - See my entry here for more things you might want to check: http://wiki.answers.com/Q/What_could_be_wrong_if_the_battery_light_stays_on_and_the_battery_still_runs_down_on_a_1996_windstar_after_installing_a_new_battery_and_alternator
The Bronco II was made till 1990. The it was replaced by the Explorer in 1991.
It depends on what you mean by computer. The '88 bronco has an TFI control module mounted on the distributor. It is held on by 2 Phillips screws and should be relatively easy to take off without removing the distributor.
is there any corrosion on the spades of the coil?or on the connectors?you say DIS,i think distributorless ignition system that an 89 doesnt have,is that correct?or are you meaning distributor cap?
Under the hood, behind the battery
on top of the intake manifold, at 2 o'clock from the distributor
disconect battery for 5 min
does your bronco have an external voltage regulator if so i would take it and have it checked
Disconnect the negative battery cable for a few minutes...that will reset the light and the computer memory. If there is still a problem, though, the light will come back on.
Your coil has a positive and negative side and if there is no power to the positive side you will not have any spark: However, if you have no ground to the negative side you will have the same problem. Check for power and ground with a volt meter.To check for power, connect red lead from volt meter to positive side of coil and black lead to negative side of battery, you should read 12 volts with key on. To check ground, connect black lead from volt meter to negative side of coil and red lead to positive side of battery, you should read 12 volts with key on.
Are you sure the battery has enough juice (13.5volts)? Is the engine locked up? Try turning the motor by hand. If the engine is not seized, take the starter off and bench test it. Recheck your negative battery cable, a very good chance your problem lies there. The same thing happened to my 1995 full size bronco today. I took the battery cables off cleaned each one, and still the same problem. I replaced the starter, solenoid, finally noticed my ground wire from my intake to the fire wall was charred. So I checked my lower battery cable connections and my ground was not connected. I replaced my firewall ground and replaced my battery ground wire and all my problems were solved. Even my dash readings were fixed, I always had crazy readings on my dash (temp, oil pressure and amp gauge) all were fixed with the installation of my new ground wires.
try to disconnect battery for 30 seconds
On a 1985 Ford Bronco II , 2.8 liter V6 engine : # 1 on the distributor cap faces towards the REAR ---------------------------------------------------------------------------------------------- Also , the firing order is ( 1 - 4 - 2 - 5 - 3 - 6 ) The engine cylinder locations are numbered : firewall 3 - 6 2 - 5 1 - 4 front of vehicle and , when looking from the top , the distributor rotor turns CLOCKWISE
Check the TFI module. It is located on the distributor.
Mine is on the right side of the distributor under all the wiring.
factory specs for distributor position then everything else is electronic
