Fuel pump will not prime!
I have a 1993 integra with an all stock b18a1. Nothing fancy. It all started when I ran her out of fuel a few months ago. I figured I burned up the fuel pump or sucked some scum out of the bottom of the tank so I bought a brand new fuel pump (import direct oreillys brand). I carefully took the fuel tank off and installed the new pump. I even dumped all the old gas out into a bucket and got all the flakey stuff out. I made sure the screener bag was clean too. Put it all back together and the pump still won't prime.
This isn't my first rodeo so next I assumed it was a bad relay. I went back to oreillys and got a brand new relay and plugged it up. This did not make a difference either. Frustrated to the max, I went through all the ground wires under the hood, cleaned them with a wire brush and fastened them back. Still no prime.
If I turn the key over the starter gives it hell and cranks like crazy but obviously with no fuel coming in it's not gonna start.
What have I missed? I know when you turn the key to "on" the check engine light is supposed to come on with the first relay tick and then you will hear the fuel pump hum through the back seat and then it ticks again and the check engine light is supposed to turn off after the pump primes... but what it is doing instead is just staying solid no matter what position the key is in. No prime, no second tick.
If the fuel pump and relay are brand new, what other conditions could cause the pump to not prime? Could this be a sudden wiring issue that coincidentally arose when I ran out of fuel? I have done frankenstein engine swaps in civics and accords and seen my fair share of problems but I've never been so stumped. I feel like a dope! Please help me guys.
