Can be a bad pump? I need to replace it again?

Hi!

I replaced my fuel pump. After I replaced it the check engine light came on the codes that it showed were PO181 and PO183. So, I called up the Nissan dealership and talked to the repair guys there. They said it can only be a bad pump and I should replace it again. So I did. As soon as, I replaced the pump the same codes keep coming up. So I don't think it's the pump. So my question is. Is there something else I need to replace when replacing the fuel pump?

Thank you!

I believe it's an aftermarket pump. I ordered it from NAPA. The only thing that I got was the pump by itself nothing else came along with.

I have tried everything. The dealer is stumped, other mechanics are stumped and I have ruled out that the gas pump is emitting some kind of electrical interference (I think). When I am at the gas pump and after I have finished pumping the gas, put the cap back on, the car won't start without being given alittle bit of gas. This is very unusual and not the way the car is supposed to start. I can then drive away 10 feet, shut off the car and then it will start fine. It starts fine anywhere else at anytime of the day no matter how long it has been sitting but it won't start after pumping the gas at the gas station. I have tried filling at different intervals (empty to full, half empty to full, etc.). It still won't start right away. I have tried sitting in a parking lot with the gas tank open and it will still start. I have tried just sitting by the gas pump, turn off the car, wait a few minutes and the car will still start. I have tried turning the key to "on" for a few seconds and then off again and then to the "on" position for a few seconds and then off again and it still won't start while at the gas pump. The dealership had run the error codes and replaced the spark plugs and a sensor and a filter but it still didn't start at the gas pump. Could it be something in the gas tank that is loose that is being disrupted by the gas being pumped in? What is left to look at?

You're problem pretty much has to be related to the pump itself. My guess might be that the pump is reacting to sudden temp change in the fuel but you're going to have to pull the tank down to investigate further.

My car started giving me problems after I took it on a long road trip. It started overheating. At first they told me it needed a radiator flush, but I couldn't afford it so I kept driving it. After a few weeks, it wouldn't start, so a relative who is a mechanic told me it was the gas pump that needed to be replaced. I had a friend take out the old gas pump, so now the car doesn't have a gas pump at all. I had it towed to Pep Boys, and they started asking me for parts not even the dealership carried. Now I'm stuck with the car without a gas pump and have no idea how to get it running again. Is it possible to order a used gas pump online or is it only from the dealership that I can order it?

Where's the old assembly?

Fuel pumps are part of an assembly and are a commonly-replaced item. All auto parts stores will have them or can order them. The question is whether it will come installed in a new housing already, or if it is just the pump and motor that has to be installed into the original housing. Often a new pump is available both ways.

There are other parts that may need to be removed, but they are not replaced. Since those are not commonly replaced, they will usually not be available at auto parts stores. Those will be dealer-only items, and even they may have to special-order them.

You can also find missing parts at a salvage yard, but if selling you a certain part renders the rest of the fuel tank unusable, you can expect to have to buy the entire tank. Often they will have a tank that was damaged in a crash so it's already unusable. They'll sell you parts from those very inexpensively.

The dealership can order any part that went into building the car, as long as it's still available. Normally it's Fords that parts aren't available after just a few years. They do a very poor job of supporting their products. Your car is 12 years old. That's a fairly long time to supply replacement parts so what you need may be no longer available from the manufacturer unless the same parts were used on much newer models. That's when a trip to the salvage yard is needed.

Auto repair shops routinely deal with the salvage yards too. All they have to do is figure out the parts that are needed or missing, then call the yard with their list. It may take a day to have someone remove them from the car, but then they often deliver them right to the repair shop.

Are you certain its a fuel problem? If its getting to injectors and stops there then injectors are either clogged or not pulsing. Will need to test each injector. May want to check compression on cylinders and check spark, may not even be fuel related issue.
