1990 f150 will crank but not start

I have a 1990 F150 with a 302 and a five speed and
it is four-wheel-drive one morning I come out in the
truck will not start I put a new fuel pump on it even
though the old one was not bad.  I put a distributor
cap and rotor on it with new wires and spark plugs I
have fuel spark and compression but still no start I
have reset timing twice.  before this happened the
truck was acting like it was not getting enough gas
at times would never cut off but it would bog down
giving it gas do y’all know things I could try to fix
this I have also tried another distributor from a
running motor and still nothing the truck Will barely
try to crank when you first start but the rest the time
will not
