Has anyone owning a 3rd Generation Nissan Maxima ever encounter a problem with the engine purging and rocking the vehicle back & forth at high speeds wanting to stall out like it wasn't getting any fuel ?
The first time this occurred was back in 2005, it ended up being the " Fuel Pump" ever since then, the problem would return with the same symptoms and wouldn't you know,.......another "fuel Pump would be acting up. This has happened (4) times since then, and more recently this month on July 3rd and I only have driven the vehicle 400 miles. I had installed a High Quality fuel pump this time " Bosch" I swore this was going to last longer, or it just may be something else or something causing the fuel pumps to malfunction. Can anyone help me on this issue or else, what I can check. I know for certain that the last fuel pump was completely dead. How did I know ? I disconnected the fuel line from the fuel filter turned the ignition to the "ON" position,....and nothing, no sound from the fuel pump and no fuel. My Son has a feeling that it could be an electrical issue with the fuel pump but who knows. Would really appreciate some feedback on this. Thanks

Have you run the car out of gas before with any of these previous pumps? Fuel pumps don't take well to being run dry.

I do believe some experienced issues with the fuel sender assembly which the top contacts would corrode and cause electrical problems such as a short.

pumps cooled by the fuel, if you run it below a quarter tank the pump heats up and its life decreases as well as silt in the bottom of the tank gets forced into the system and can cause clogs and pump damage

Not familiar with the VE motor, but do you have a fuel filter and fuel pressure regulator? I would change those with the next fuel pump replacement, especially if they've never been changed before.

It's your fuel pressure Regulator.....I had that some thing happen using that Nismo adjustable FPR (fuel pressure regulator) except at idle and I couldn't get the Nismo AFPR to set on it's seat solidly at idle and it would just keep bouncing off it's seat at normal fuel pressure levels so I removed it and upgraded to a Performance Products AFPR and the problem went away.....I would If I were you see if you could locate a decent salvage FPR and install it maybe a couple and see if they make a difference but what you need more than anything now is a 0-100 psi fuel pressure guage on you fuel system you can see if the regulator is bouncing off it's seat causing the pressure flucuations....if it is, order a new one!

Yes, there was fuel in the fuel tank.

MaximumRPM

No never ran dry. "Low" perhaps but not dry.

Sounds like a winner. I'll try that and see.

Going to check out the fuel pump again to notice any fuel flow when I turn the ignition first. Thanks

I doubt all those pumps went bad. As stated previously by somebody else, it's most likely the hanger assembly itself wonking out. They have those exposed/soldered wires on them that corrode and generally crap out. I have gone through several hanger assembly's myself. It was a poor design on Nissan's part to do that.

Put 12v directly (very briefly) to your fuel pump and test it that way. I mean bypass the hanger assembly wiring, go straight to the pump.

My 94 GXE is on it's 3rd fuel pump in 194k mi. Turns out the pump overheats and blows the fuse. Once the pump motor cools off, it will restart (w/ new fuse of course). The last one crapped out on me in the middle of the interstate at rush hour in north Dallas! Not fun. I think this pump motor design (I think it's a Bosch) just lends itself to failure due to either the bearings wearing out or internal short in the windings and overloading the motor circuit. That makes the circuit overheat and blow the fuse. Luckily they're easy to access and replace once you take out the back seat. Just keep spare fuses w/ you.
