Being as this heater is 1998 I think I;ll spring for all new. With a quick look I hope there is a panel at the back of the heater under the coach to disconnect water else I'm stymied before I start. Also my heater model indicates it to have an engine heat exchanger. Any one that can offer some insight on how to attack this thing is welcome. I have the electric bypass switch for winterizing but we'll see how well that can be trusted. I really hope the engine is not actually connected as chances are I'll be dumping antifreeze as well.

what kinda heater is it? atwood? suburban? 6 or 10 gallon? if i knew which you have, i could post some troubleshooting info.
can you light the burner with a barbeque lighter?
if you have an atwood, after doing the checks you have already done, imho the next thing for you to check is the plastic covered fuse on the lower part of the outside panel. you can remove it and check it for continuity or just jumper it out of the system for troubleshooting purposes. the purpose of this fuse is to ''blow'' if there is enough blowback heat from the burner to avoid a possible fire.
the engine assist water heater is a short piece of piping connected to the back of the water heater. on my moho, it is connected to the engine with 5/8'' rubber heater hose.
you will loose some coolant if you disconnect the lines.
it acts to transfer engine coolant heat to the back of the hot water tank.
on my moho, it keeps the water warm quite well while we are under way.
