Re: MERCRUISER 3.0 WONT START
Hi<br />Try this advice I got from Captain HooknFinger when I had the same problem:<br /><br />-Sounds like you have an electrical problem causing weak spark at start up.<br /><br />- You should have full 12 volts at the coil when you are starting the engine.<br /><br />Try these quicky tests... <br />- Attach a jumper wire from battery positive to coil positive and attempt to start the engine. (You really should change the spark plugs before you do this test ), because they are probably junk by now from trying to start the engine with weak spark. <br /><br />*Engine starts ok? with 12 volt jumper connected?<br /><br />Your carb, distributer, coil, plug wires are all fine - Trace the wires feeding your coil in the key 'start' position. Something along there will be junk or grounding out on route to the coil. <br /><br />*No start? - with 12 volt jumper wire connected?<br /><br />- Distributer internal parts or distributer itself may need replacement.<br />- Spark may be grounding out inside distributer.<br />- Bad coil, or coil wire.<br />- Dirty, worn or cracked distributer cap.<br /><br />One test you can try to see if the distributer is grounding out..<br /><br />- Remove the distributer cap.<br />- Attach test light ground to distributer housing.<br />- Turn ignition key switch to (RUN) position.<br />- Use a screw driver to Open and Shut the points causing them to spark while at the same time , you stab the inside housing of the distributer with the test light probe.<br /><br />*Test light does not light up or flicker?<br /><br />- Head for the high voltage coil wire and/or coil.<br /><br />*Test light - lights up or flickers?<br /><br />The internal parts of the distributer or distributer itself may be bad/grounding out internaly.<br /><br />Affa
