I have an 84 civic 1500. It started dying on me , then would start and run for about 1o mins then quit. Now it turns over is all. I have replaced ig. cont .mod , new wires , cap/rotor , its getting gas and has juice on +/- posts and turns over fine ? It appears no spark is going from coil wire to dist cap. How can i test to see if coil is sending power to cap , ect. ? Any suggestions ??? Thanks
