OK, now lets pull the cap off of the distributor and check the power at the coil to make sure you have power at the coil.
Then we can better determine if it is the ecu... there should be two lugs on the coil and when the key is on the positive lug (maybe a Philips head screw) will have power all the time..

Hey finally got warmer n I checked fuel pump it works n has only constant power I checked dizzy for power and coil has constant power computer has power only on two terminals ignition n I guess constant power but no spark is there a way to jump dizzy n fuel pump n get it running

ok im having the samei issues. i was checking the plugs and when i pulled number 3 the engine shut off and now i have nothing. i did the tune up (plugs,wires,cap,rotor.) and went to start it and still nothing i did all the things you have all mentioned ubove and nothing what is the deal with mine? thanks peeps. hope i can get her back to life soon.

Check the Ignition control module,most of he time its that,first check if you got power on the ignition coil if you got power,them move to the ICM

well after checking eveyuthing twice it was the dizzy the little chip inside was burnt... thankfully i had warranty on the part so i just took it and got a replacement thanks for the quick response...
