B3Mog, thanks for contributing a possible solution, much appreciated. and more so when it worked....
Using no more than logic, using the method you suggest, reduced the amount of "suck" required by the pump gears in order to get to prime it`s self given the rise in the level of oil in the sump....? Perhaps less expensive to use an oil can to pump some pressure back into the system, although that seems not to have worked in this case... Pity.
Pumping a bit of oil with the can into the galleries also seems likely to restore some lube to the areas that began to rattle a bit when last ran with no pressure, which seems somewhat comforting, prior to spinning things over again..?
No oil pressure whatsoever when the last time the engine ran was all good, points initially to a non functioning oil pressure gague, if not that then the next logical issue would seem to be the oil pump loosing prime, which from reports seems to be a rather well known issue, and more so following an oil change....!
For sure one can ramble on about a whole load off issues such as the oil pick-up being partially restricted combined with a loss of pump efficiency due to lay up, which together could create a similar outcome, but one step at a time, canceling out the simplest options first, may provide the leist complicated solution..... or NOT..?
Still keeping my fingers crossed.
