"Yikes you won't believe t
"Yikes you won't believe this one. Maybe I am missing something. I was out on a little evening cruise with the wife and lost power. Phoned a friend and got a tow back to marina. Checked gas was squirting into carb, so pulled a plug and noticed no spark.
Just to be stupid, I took a wild guess and replaced the coil ($69). Still no spark. So I broke out the troubleshooting information and followed the flow chart and it seemed to indicate i needed to replace the sensor in the distributor. So, I pulled the distributor replaced the sensor ($69) and was surprised when there was still no spark. Just for the record, there was 12V at the + side of the coil but no pulsing of the negative side. Also, had 12V on red/white. Striking reg/green against ground seemed to produce a spark but it was not consistent - so what the heck, I replaced the computer module (ouch$$) and then by golly still no spark. At first I had a good pulsing on the negative side of the coil but it dissapeared as soon as i put a spark tester on the coil. Checked all grounds, everything seems right...followed the chart again and this time i was definitely getting spark when striking the white/green so the chart said - replace the sensor. Like an idiot, I bought another sensor thinking maybe first was bad out of the box. Same thing happened. As soon as i put my test light on negative of coil i was getting pulsing, but as soon as i connected the spark tester there was no spark and no more testing. Well, now I am at wit's end. I am mechanical and electrical and usually nail this stuff quickly but I am clearly doing something wrong. Also, by the way, i disconnected the shift interrupt switch by removing the associated white/green wire and also took the tach out of the circuit by taking the correct gray wire off the coil negative. Still no sparky. I am stumped. and I know, I violated the rules by replacing parts without being sure. Also replaced the dizzy cap and rotor...HELP brothers....EH Carumba!!!"
