Weak spark + 1988 ford bronco

I have an 88/89 ford bronco with a 351 windsor. I recently replaced all the gaskets, flywheel, a new rotor and cap on the distributor, spark plug wires, and plugs, electronic control module, and now i am getting very weak spark and it will not start. What could be the cause of this? thanks

Check the voltage of the b+ terminal of the ignition coil (primary side) with a cheap multimeter while cranking. low voltage to the primary will cause low voltage on the secondary. also recheck all ground paths from the ignition module. ensure good connection from coil to module. note: new parts are not "known good parts" until it runs.--> IG.MOD.

1986 bronco 2 sputters and then is fine then sputters


Could be fuel or ignition related based on your description.
You would need to figure out which problem you are dealing with to proceed. Could be a weak fuel pump, or dirty filter, or problem with the injectors if it is fuel related.
Then there is the ignition system to troubleshoot if it is a lack of spark.
A weak coil, ignition module, cap and rotor, or spark plug or wire.

On a 88 bronco i can not get spark but have 12volts getting to coil, replaced.. coil/cap and rotor/and ignition module


You will need to change the pick up coil that is located in the distibutor. if you have never done something like this you would be better off to let a garage do it, reason you have to pull the distributor out of the engine.

Weak spark from dist cap to plugs. spark from coil primary is as it should be. Plugs were carbon fouled from rich condition. this is a 92 bronco 5.8 windsor motor.changed out plugs,cap,rotor,and remote tfi...


The engine is definitely in an over rich fuel condition if you are blowing black smoke. I would suspect a bad 02 sensor, but the flooding condition you describe at starting could be other things. I would check the codes and proceed from there.
