My 83 seems to be hexed. it will start and run fine when it wants,then with a loud click under hood it shuts down. No spark from coil and fuel pump does'nt seem to run. Have tried different coil, disty and module, and fuel shut off module, all to no avail. It will still have power to both sides of coil, and will crank, but will not start or have spark or fuel. Any suggestions as to my problem?
