THX1138 is on a distinguished road
92 k1500 5.7 will not start

I am new here and need some help. This truck was running until I replaced the spark plugs. Now it will not start. I have checked the coil, got 12v on + side. Checked the ICM it is good. I changed the spark plug wires and coil. I bought a new distributor, nothing. I do not have spark. Everything looks good, but I could be missing something. Any ideas?

Thanks

have you checked the stator"pickup coil" under the rotor button, or check the ing. control mod. one or both of those could be bad.

did you plug the distributor plugs back in? do you have 12V going to the "dizzy"? is the firing order is correct? maybe the ECM fuse got blown somehow. check fuses.
I would suspect this last but at the same time dont over look that even tho the parts are new the can still bad out of the box.

Thanks for the reply. I have checked everything that was mentioned. The fuse is good, checked all with meter. Yes I did plug all connectors back to the dizzy. Checked pick up coil.
thanks again for the reply.

Are the plug wires on the right plugs?

Yes plug wires are on the right ones. Spark plugs gap at .035. Did find pick up was bad, exchanged for new one. Still won't start.
Thanks for the replies.

Check to see if you may have knocked the Oil Press switch plug off when changing the Dist. Listen to see if the fuel pump is running because if the pump is running then the plug is still in. Oil press switch controls fuel and spark shut down in the event of lost oil press.
