Well its not a pinhole in the pickup tube. Have started or seen the boat since sunday. Started right up. So i be thinking... What about the internals of the distributor, can a pick up coil go bad? Can I use a igntion module from a car to test it again? Does anyone test ignition modules? Thanks Steve "Florida wrote in message b.com...

OK let me start over, It is the Chevy 3.0 litre engine.(4 stroke) alpha gen II outdrive. a 2005 to be exact. Symptoms: Will run great all day, when it gets to a half tank or at the end of the day, it will start and run fine, but when it idles for longer than 10 minutes, it will die. Then after it dies, it is VERY hard to start and will only stay running at over 2k rpm. go back to it in a day or so, it runs fine Runs great all day. So it's not a heat/electrics problem. Half tank it gives problems. That means a bad fuel pump or bad tank venting. Check fuel pressure at full tank and at half tank. Simple. Bad tank venting. I hadn't seen that yet, but it sounds like it could be the problem. Create a vacuum and you've got a problem. Good 'eyes'. Another guess. Pin holes in pickup tube in gas tank. --- Posted via news://freenews.netfront.net/ - Complaints to --- The trigger module in the dist. isn't that expensive but you may have to replace the trigger wheel too, since it may get damaged upon removal to get at the module. One more thing. Have you checked the coil high tension lead? If it's resistor wire it should read 1 or 2 K ohms otherwise 0 ohms. |
