I have an '86 OMC GM 2.5L that is in a '86 Stingray 190 SVC SS that I am trying to get running again after being properly laid up for 10 years.
I recently rebuilt the carb and replaced the water pump. Now I'm trying to get it started again. Using a good battery I was able to get it to turn over, but it wouldn't even think of starting. I tried a small burst of starting fluid in the carb with the same effect.
This took me to the electrical side of things. I replaced all four spark plugs, though they looked good, with the same effect. I pulled the number one wire off and tested the spark with one of the old but still great looking plugs with no spark. I then pulled the high tension lead off the distributor and set it up about 1/4" from a jumper cable lead from the neg terminal on the battery and still no spark. I then tested the resistance of the coil and both primary and secondary were testing within specs.
I then tested the pos side of the coil to the neg battery terminal with the key in ON and had no voltage showing on the multimeter. So I came here and read the various stickies. I'm now going to work my way back from the pos terminal to the key to find where I'm losing power. I'm really hoping it's something simple as I want to run the boat Labor Day weekend.
PS. I wish I had found this forum yesterday as I could have gotten a ton more done on it troubleshooting wise. Instead I washed and cleaned the boat from top to bottom. Damn for a 30 year old boat she is beautiful!
