I have changed out everything. Can someone help. I changed the dist, coil, module, relay, wires, ecu. What should I check next?!

Is the ECU getting power? Do you have a multimeter?

first check signal coming out of dizzy, if yes move to coil, if no its a problem in the dizzy

check power to coil, check signal to coil, if you have both of these, the coil should function, check coil output, if no output, check coil resistance. if coil is good, wires and plugs.

check your engine grounds too.

basically either there is a problem with a component in the ignition system, or your ecu is seeing some reason not to give spark. you will be able to determine this by scoping the trigger signal going to the coil.

hope that gives you some place to start
