Battery warning
codes = no
Repairs done prior = none

tech = jk
question = My battery light came on and now the truck will not start

JK:
A battery light coming on is almost always a charge system problem. First,
check all fuses. Then if you have a
volt meter, put that on the battery when
running. You will have to get a jump start. Should have approx. 14 volts
when running. If not, then most likely a bad alternator.
Also be sure to check that the battery cables are clean and tight.
Question: I have a 2000 S-10, 4cyl. 2.2 liter engine.  On days when it's cold and wet,
damp, or just moist, the truck will not start on it's own or sometimes not at all. On days
when it is sunny and warm it starts with no problem. At diagnostic check determined that
the 3rd wasn't firing properly so I replace the coil pack for that cylinder. Today it is cold
and raining and it won't start.  What is the problem?
Answer: Most of the time a no start or hard starting problem
when it is wet outside is caused by a bad distributor cap and
rotor, which your truck does not have. The other common cause
is bad ignition coils. They may have corrosion on the towers, or
be shorting out internally. Next is bad spark plug wires. They are
susceptible to moisture as well. Check  for spark at the spark
plugs when it is not starting. Then look closely at the plug wires.
Another way is that when it is running fine, spray them down with
a water bottle and see if the engine stumbles or actually see the
spark jumping out of the wires.
