Fuel Pump issues, Sometimes primes and sometimes not

[Kvng Cotto]

having trouble on what exactly could be my problem. i have a civic ex with a b20b w new walbro 255. before i replaced the fuel pump, the fuel pump would not prime after not driving it for some time. i tried replacing it to see if that would work but it still has the same issue. when the fuel pump does prime the car runs as it should. the civic also has a new main relay and im positive the geound on the thermostat housing is good. im starting to think it could be my ecu but i dont have another ecu to test. runs on hondata s300. could it be maybe the ignition switch or possibly the wiring to the fuel pump? any help is appreciated thanks

On my 5th generation, the same problem turned out to be a bad capacitor (Capacitor C14) on the ECU. Capacitor replaced, problem solved. I don't know if this is an issue in the 6th gen.

Cranks, but wont turn over. 95 Civic DX

First of all I checked all the old posts regarding no start problem. Car has 40k original miles and ran great. Excellent car. Yesterday morning, went out to start it. Able to crank the engine but it doesn't start. Battery is fine. Checked for spark and there is spark. Cleaned and tightened...
