[DML] Cold Start System

[Todd Nelson <tan5732@xxxxxxx>]

List:

In my attempt to figure out my occasional odd starting problem, I think I may have found something and would like your opinion.  I think my problem has been lying in the fact that my cold start valve never actually fires.  I have verified that the valve itself is operational by replacing it's power source with that of the CPR, and gas squirts just fine.  So you are probably thinking that my thermal time switch is bad, I ruled that out by verifying that there is continuity between the two terminals on the TTS when there should be.  I even bypassed the TTS altogether and manually grounded the cold start valve and still nothing.  Then I put the voltage meter on the cold start valve connector and found that there were only 9-10 volts while cranking.  Is this enough juice to fire the cold start valve?  I figured it would need a full 12, so this lead me to think that maybe my starter solenoid is failing and not giving enough voltage to the cold start valve.  Do you think my conclusion is correct?  However, it would seem odd that my starter solenoid would be failing yet the starter motor itself would function just fine, but I guess it's possible.  Also, I have taken off all of the solenoid wire connections and cleaned them thoroughly and the battery is new with a full charge.  Kevin, you mentioned a while back that you had the same issue, you may want to check the voltage to the cold start valve too.

Also, thanks to John Hervey for spending the time on the phone yesterday about this problem.

Thanks,
