1990 Acura Legend Fuel pump cycles but does not deliver fuel to fuel filter?
Fuel pump cycles but does not deliver fuel to fuel filter?
What is your question?
Started with occasional no-start, went to no-start at all. Replaced main relay. Turn key on, hear and feel fuel pump cycle, but do not see any fuel being delivered. Can a fuel pump fail that way?

There is no fuel getting to the engine. So it doesn't seem a pressure test would measure anything. Similarly, without fuel don't see where an injector pulse test would be telltale.
You stated that you hear fuel pump cycle , I was going off of that tidbit - now , you KNOW BEYOND A SHADOW OF A DOUBT , THAT THERE IS ABSOLUTELY ENOUGH FUEL IN THE TANK?THEN TIME TO PULL THE PUMP FOR INSPECTION.
Got it started after replacing fuel pump. However, I am not convinced the fuel pump was the problem as opposed to perhaps low voltage to the fuel pump. Because while replacing the fuel pump, I tested the new one, and discovered it failed to pump when attached to the car and put in a bucket of water, despite spinning. Next I took it to the bench and test with a batter jumper and it pumped. So I installed it, hooked up the jumps, and got it started. Thanks for your assistance.

Ok, added a few gallons of gas, still no gas to engine. Replaced fuel pump and main relay. Will test tomorrow after battery charges.
Okay and sorry I didn't notice the 'caps lock' was on before. Good luck.
