Car doesn't want to start after it's been sitting for a while and the problem is that the fuel pump doesn't want to prime itself.

I'll cycle the key on and off a few times randomly and wait and eventually I hear the fuel pump prime and the car can be started.

I don't think it's the main relay as I've swapped in another main relay that was known to be in perfect working condition and the problem still persists.

If anyone has any suggestions as to what could possibly randomly delay the pump from priming or anyone had any similar experiences, help me out here.

Car is a 95 integra and it's a Walbro fuel pump.


After I get the pump to finally prime, I can turn the key off and back on and it'll prime every time. Also, after driving the car any amount of time I can turn the car off and turn it right back on b/c the pump will prime immediately.
