I have an 88 civic hatch that was sitting for the past 8 years. I had to in stall a new fuel pump, timing belt, water pump, both injectors, and fuel filter along with all the normal tune up parts. when I fill the gas tank it runs like new but once it gets below half tank it starts acting up. It runs okay until I get get off of the gas, like when I'm drifting to a stop sign or when I come up on slower traffic. When I get back on the gas it either cuts out or it surges (like I'm pumping on the gas). I thought maybe it was a fuel pressure regulator so I replaced the one that was on it with the one from the old throttle body but it still does the same thing. As I said before it's a new fuel pump and filter so the only thing I can think of now is that maybe when I remounted the fuel tank maybe I kinked one of the rubber fuel lines. I'm looking for further input because I think I did a pretty text book install on the fuel pump. Any thoughts would be appreciated, thanks.

Might be the sock filter on the pump. Nobody seems to have much luck with anything aftermarket.

I haven't done any aftermarket yet. I also want to add that the engine fluctuates at an idle, if that helps

You changed the fuel pump.

Did you reuse the factory sock filter?

mech187

I thought you were saying upgrades, but yes the oem pump I installed had the new filter in it

If you didn't get it from Honda, it's OEM replacement, not OEM, thus aftermarket.

Try getting a Honda sock filter and putting that on, and also make sure it's pointed in the right direction.

from all of the threads i have seen pop up with this problem it always ends up being the sock on the fuel pump

So I dropped the tank and tried replacing the sock. Of course I started it before putting the tank back up and it runs like a champ. Problem is as I raise the tank it cuts off now. So runs awesome with the tank on the ground but dies out and stalls when I'm putting the tank up. I checked the lines and I can't find where I'm kinking anything it's driving me nuts

Try looking at the direction of your fuel filter. Typically its a no brainer but- There is a arrow which indicates Flow ---->

So with that said- could be a fuel filter installed backwards. check fuses as well. could be a bunch of stuff.

Test pump for 12v if you can.
Make sure it primes and you can hear the 3 second whine
