"I just acquired a 2005 Nissan
"I just acquired a 2005 Nissan 18HP 4 stroke. It looks like new, the oil looks like new. It starts right up, sounds beautiful but the red oil light stays on and so it 'clips'above an idle. I have replaced the original oil filter which looked clean. I cranked the engine with the filter out and oil did bubble up in the filter chamber. I replaced the filter and pulled the oil pressure sender and fired it for a few seconds. Oil wells up in the drilling but does not have pressure or volume. I have let her idle as long as I dared and she won't start pumping. What do you think?"
