I've seen shade-tree mechanics so injector work, but imho, this might
be something for a professional mechanic.

Good luck,

Before you jump to any conclusions pull the vac. hose off of the fuel
regulator and check for fuel. If the diaphragm in the regulator springs a
leak, fuel will flow past that leak and right into the intake manifold
through that hose. Hard starting when hot is the usual complaint. Let us
know what you find.
