i have a 93 civic vx hatchback. when i turn the key to the on position, everything comes on but the fuel pump and the check engine light stays lit. if i just leave everything alone sometimes the fuel pump will just come on for 2 seconds then i could start the car. tried 3 different main relays, nothing helped. the plug to the fuel pump has constant ground, it just gets power whenever it wants. but once the car starts, its fine never cuts out.

 

maybe a faulty fuel pump. do you know how to check for codes since your check engine light is on?

 

the fuel pump is a brand new walboro installed about a month ago, never gave me any problems. the check engine light only stays on until the fuel pump decides to turn on. and when its on i try to check for codes but bridging the two pins on the connector does nothing to the check engine light.
