2000 Honda Civic Hard starting after replacing fuel pump. Sign In

So I bought a 2000 honda civic dx 5-speed and after having it awhile my mechanic told me the fuel pump and fuel tank were really old and dirty. I replaced both and noticed that after driving about 230 miles (i can usually get around 325-350 on a full tank) the car has trouble starting. You try to start it and it just doesnt for an extra 1-2 seconds. The less fuel thats in the tank the longer that delay is. Also if I have trouble starting it but drive somewhere and turn it off and turn it back on again within maybe 30 minutes to an hour it will start no problem. Somebody recommended i change the fuel filter and I did and that helped now i can drive about 300 miles instead of 230 before it starts having trouble starting but the problem is still there. I did some research and found other people have this problem with a number of different cars (link deleted,.............not allowed) I found out that if i turn the key to the on position without starting the car and let the fuel pump build pressure for a few seconds I’ll be able to turn on the car with no issue. That works fine and the car works fine but I’m trying to find a more permanent solution. It seems the fuel pump just won’t consistently hold pressure while the car is off and the fuel tank is low where as the old pump seemed to be able to do that just fine. The people at autozone insist I have the right pump model for my car (spectra premium fuel pump hanger assembly part number: B8341H) and the mechanic insists its installed correctly. Does anybody have any insight as to what is the root of this problem and how to actually permanently fix it?

You say you replaced the tank. Where did this tank come from? Was it new?

You have typical fuel starvation symptoms. Just make sure it's not a tank problem before replacing the pump. I would use a different brand this time.

The tank was also brand new ordered online but I also did double check and make sure it was the right kind for my car. and as with the pump the mechanic says its installed correctly. I don't understand how it could be the tank though. Or rather I dont understand what could be wrong with the tank that would cause this. What would I ask somebody to look for if I had them look at the tank? The way it sits while attached or something else?

Most electric fuel pumps sit in a compartmented area inside the tank to fight sloshing. These compartments are fed through small tubes usually and in older tanks they can be restricted, starving the compartment for fuel supply but in your car, it sounds like the fuel pump is either wrong or defective.
