further update
update:
1. new Optima battery
2. now 1/0 positive cable
3. fuel filter bowl is 1/2 full - which is ok
4. new 1/o ground directly from new, fully charged Optima 6 volt battery
5. `I have spark, but turns very very slow, and sometimes not catching.
6. my next move is to remove the starter
\
keep in mind, it was running just fine, then it got colder, and troubles began
is there a way to test the starter in the vehicle to see if its bad or is removing the starter the next step? I have never done it but looks pretty simple.
thanks
