The problem resolution could not have been simpler. Fuel Relay
A big relief for me as I was not looking forward to dropping the fuel tank. (full)
For the record. Turning the key on will give you about 5-6lbs of fuel rail pressure. With the engine running its around 25lbs.
Our 98 Sun Sport does not have a booster pump. However I will look into potentially putting one in to bring the pressure up to 35-40lbs. The only hang up would be to tap into the 12vdc fuel pump power line. I would do it with a shielded pair conductor.
I am guessing the 4 additional relays to the left of the power distro box many be related to either the 6.5kw generator or maybe the two A/C units on the roof. My service manual gives no reference.
All relays are FOAB-14B192-AA which have common replacements at Amazon or any auto store. It would be a good idea to have a spare on hand....
