Hello everyone I'm new to the forum and having a no spark issue. My motor serial # 0l092658
Transom # 0l294350
Drive serial # 0l422426
My boat is a 99 vip vidicator
Boat started up fine a month ago but now it won't fire up. Cranks but won't start. Replaced battery. Checked spark with spark plug tester tool and no light. Checked with test light and I was showing power to coil and from coil plug that connect to the ignition control module. My good ol neighbor said probably bad ignition control module and to buy new coil just in case. Well I bought the coil and the ignition control module and it won't fire. Before I cancelled out the 2 new parts can someone help explain difference between a mercruiser marine coil $165 and ignition control module $250 between a autozone gm coil $25 and icm $40 parts. Icm looks identical plugged right in. Coil looked same but was missing braket riveted to coil to mount to motor, but also plugged right in. Im confused to what's the difference besides marine price being quite more. Since I see power from the plug coming from the coil before the icm my neighbor suggest the icm. After I replaced the 2 parts and to no avail I put the old parts back in. Now my neighbor thanks it's the distributor. Before I spend anymore money I would like your guys advice.and tips for testing to verify. I was also leaning towards the pick up coil in distributor. Im no expert with meter but when I tested the pick up coil I was getting weird readings and I was assuming I tested it to be bad but need help with meter. When I tested wires from pick up coil to ground with ohm meter set m I was seeing 13.8 m ohm. When I tested 2 leads together I was seeing range from 1.4 ohm m to 4.3 ohm. Services manual says I should see infinite when to ground and as close to 0 as possible when leads together. According to my test is the pick up coil bad? Sorry for the book, hope I explained everything well. Thanks
