You have probably burned the fusible links.  These are fuses
in effect which look like wires including the one near the
solenoid that you replaced.  They have specific electrical
qualities to function as a fuse.  They must be replaced with
like links of the same length to function as intended.
Regular wire will not replace a fusible link.  You truck has
several of these all of which are required.  When you are
using the starter, the ignition is supplied thru the start
circuit.  When the switch is released to run, the ignition
is supplied thru the run circuit.  There are fusible links
for the run circuit and the ECM as well as the fuel pump
IIRC on that one.  I do not recall the exact location of the
fusible links.  I believe they were all yellow in the
harness on or near the left fender.  Make sure you replace
them with the correct links.  You need to get hands on a
vacuum and wiring manual for it which will give you all the
info needed to quickly locate and test the circuits.  It is
probably still available from Helm, inc or can probably be
found somewhere on ebay.
