Stuck in the 'wilderness' with a 98 Ram 1500 4x4 5.9L that won't start.
Had a check engine light prior to problem, but was unable to get it
checked.  Light went off on it's own, then a couple days later the
truck wouldn't start (after sitting overnight).  No noticeable symptoms
prior to that.  Have no spark at the coil output.  Checked all fuses in
both boxes, all OK.  Was able to get a new coil and installed that,
still no spark.  Am thinking probably the crank position sensor or
distributor pickup.  I have 1 shot at getting parts shipped to my
location, but it's going to take 2 days for stuff to get here.  Don't
have access to a Dodge mechanic or code scanner to verify problem (have
access to a GM mechanic, but he's never worked on a Dodge before).
Fuel delivery appears to be functional.

Do I go ahead and order both the crank sensor and the distributor
pickup (cost $200)?  I'm guessing yes, as a just in case.  And, where
exactly is the crank position sensor located on this truck?  The GM
mech says they are usually on the front of the crank for GM's, but I'm
not seeing anything in that area.  The online parts stores list
separate sensors for auto and manual tranny versions, so I'm going to
guess it may be located on the bell housing somewhere?  Are there any
other potential causes that I'm missing and should be looking at?

TIA,
Scott
