Fuel Pump Priming, No Fuel Draw from Pump

Recommended Posts

Hey guys,

I changed my oem fuel pump on my R33 GTR with an AEM 50-1000 unit. The pump is priming (can hear it, even took it out wired so make sure) but it isn't drawing fuel. It is getting a signal from the relay in the boot to run when trying to start but it simply isn't drawing fuel even though I can feel the pump trying. Everything electrically seems to line up and is wired correctly - my battery voltage is a bit low, sitting at around 12V but the pump should be able to draw at 8V.

 

Any thoughts? I'm really just out of ideas here, Ive checked nearly everything and the only thing I can think of is the pump is bad.

 

Thanks!
