86 5ktq starting hard

[Jim Herzig <jimzig@athenet.net>]

I have an 86 5KTQ that is starting hard on occaision.  It has 178K on it
and i have replaced plugs, fuel pump and filter, air filter, front
intercooler/turbo hose, etc.  It runs fine even under full throttle(no
surging) but it starts very hard sometimes.  For example, I go to work at
8am, starts fine.  I go to lunch at 1pm  starts like shit.  I go home from
work at 5pm, starts fine.  I go out after work at 7pm  starts fine.  The
next day it started fine in the morning but hardly started, took at least
5-6 attempts, at all at 1pm when I went to lunch again....frustrated.  The
starter sounds like it is fine as it is turning the engine over but the
starting, or lackthereof, is much like trying to start a flooded engine but
I haven't given it enough gas to do that.
