HELP ! No Spark
New guy needs some help.
I just bought my daughter a 90 Bronco with the 5.8 ltr.
I changed the distributor ( new, not reman with a new module ) and now I can't get any spark from the coil.
I changed the coil and yet another new module and still no spark.
Is there a computer or code I need to reset ?
I have a Haynes manual and have followed the trouble shooting guide and this seems to be where it points.
I'm at a loss,this is the newest, most high tech engine I have ever worked on. ( Don't judge me )
Thanks
Allan

Does the CEL come on when you turn on the key?
Do you have power to the Ignition coil?
Unplug the computer and see if spark returns.
If it does then check the small ground wire (black with a green stripe) at the battery NEG post for a good ground.
Then check to see if the ECM Power relay (brown bottom) is closing (clicking) when the key is turned on.
If the relay clicks and you have a good ground at the battery then replace the computer.
