Re: ignition problems
Only a thought, but if you end up on the block "Replace Ignition Module" and given the heat related nature of the problem, you might be able to further isolate before purchasing, which I assume to be an expensive part. My thought is to use some "cool it" type spray. This is common with elec techs, for component or bad solder joint isolation. Should be able to find at Radio Shack or other electronics supplier. What I have on hand is "Freeze Mist" made by GC electronics. You do need to be careful with it, because it is capable of some very low temps, minus 60F with "Freeze Mist". After applying some directly on the module, if your engine starts afterwards, would check the module mounting. I am pretty sure some type of heat sink compound is used between the module and the metal mount. Maybe worth redoing this heat sink mounting before replacing module. I don't believe anything is repairable on the module, unless you see exposed solder joints. <br /><br />I would like feedback from others on this, especially if this stuff is a no-no for boats. The stuff I have says "non-residue, non-flamable, and contains no class 1 or 2 chemicals". <br /><br />Given my understanding of how the knock control system works, I'd say it is unlikely causing the problem. The knock module either applys a signal to the ICM or it doesn't. Would change the advance timing, but shouldn't cause it not to start.<br /><br />PS: I am curious on what one of these modules cost.
