Well i am by no means an  expert with these things but here goes.
First these heaters do cycle on and off once the heat exchanger gets hot the
flame will extinguish and the pump will stop ticking but the auxiliary fan will
keep blowing the heater will light when warmer air is required. are you sure
the pump is pumping fuel or is it just ticking?and if it is working were is it
going?that would worry me.Next i would make sure it is getting spark to the
glow spark plug you can pull it out and check it,i would disconnect the wires
from the fuel pump and run the heater touch the plug to ground somewhere and
look for spark.Well these are just a couple of ideas if you have any more
questions please let me Know.
