Computer Code 18?

[bfiakas]

Had a code # 18(M) today,and as I was checking for the possible cause I found out that my Bronco would start with the sprout plug OUT.But when I put the grey plug back in it would not start? I installed a new computer,ignition module and distributor two weeks earlier and had no problems. I rang out all the wiring for all the circuits from the module plug to the computer plug and all are good.I also replaced both the fuel pump relay and EEC relay because I had code 96 earlier and that has cleared. Before I condemn any part I installed, is there any other testing I need to preform?

I found the test procedure #8 to test the timing advance.I ' ll see if that solves my issue

Can you give some more information year model Bronco? What's the problem it won't start? After the parts replacement.
