My 92 accord keeps shutting off on me. has new main relay. I've tested the voltage at the relay and harness at the pump when it shuts off and nothing. I've tested the injectors while cranking with a light tester, and they pulsate like their supposed to. I have spark but no fuel. mainly does it in the heat. Can anyone help me with this. I've been down for three weeks now.

 

So you are or are not getting power at the pump? Your fuel filter is probably clogged if not the fuel filter is just plain broken.

 

the filter has only been in for about 4 months and it will run fine but then stumbles and shuts off. it just completely shuts the power off to the pump.

 

Are you sure its killing the pump? Could be a clogged cat, or perhaps even a bad oxygen sensor.

 

Turned out to be the screen filter on the fuel pump
