dakota with no spark

i have a 1994 dakota 318 5 speed 4x4 it has no spark i replaced the coil the crank position sensor the pickup coil chacked the fuses and relays and still no spark i think the only thing i have left is the computer on the fender unless anyone has any more ideas the voltage going into the coil on the primary side is around .15 volts and that seems really low so any sugestions that anyone may have would be greatly appreciated thanks jason

Behind the windshield resivior tank,ther is a gang of wiring.One of those wires corrodes and breaks off.This will cause it and this one place to check.It is a common problem too.

Another thing you might try, is to unplug the o2 sensor. The heater circuit for the o2 sensor--injectors--coil, all get their voltage from the same source, I believe. I have heard of that heater circuit shorting and causing problems.
