Looking for the signs is as much a safety precaution as it is checking for problems.

It is simply what has to be done.

Signs a Fuel Pump Is Failing

Is there any way to get the reliability up with, lets say 90% that the engine will never pop assuming proper use of the car? Because the fuel pump is the component responsible for supplying the engine with the fuel required for it to run, any issues with it can cause major drivability and performance problems. I just knew that at some point down the road my car will need them after I build a stronger bottom end for it.

Think its two bolts with an allen key head so easy to remove. The engine is actually lacking fuel so it is dying and then starting back up again. The 370z unit has all external plumbing, so you will see black nylon hoses connecting the components within it.

And when the pump sucks air, it suffers the consequences. And that was with me and a couple friends pulling the motor disassembling it and having a machine shop build the short block. That's exactly what happened to my car, and it'll happen more often later. Sounds like what my car was doing when my fuel pump was going bad. I hope Andy gets sorted. But I haven't looked into uprev in a long time. Like any device, however, fuel pumps can and do eventually wear out after thousands of miles of use.

As your fuel pump begins to wear out, its components often wear down at different rates. As a matter of fact, in my own car, I am using E85, which requires significantly more fuel quantity to acheive the same power. I've tried both my keys with no luck. Some drivers may confuse this sign with the effects of dirty gas, but modern fuel standards make a failing fuel pump more likely.

After running the motor for a little bit I pulled the 4 plug and it's got fuel on it so I know the injector is spraying. Is the block totally custom built for the turbocharger in that case? And it's never happened until I've been driving for at least 15 mins. I did pull the 4 fuel injector and replaced it with a working used one, with new o-rings, and it's still missing. The old 3-wire rectangular bulkhead connector is just left disconnected. My idea would be to run a second well nut to supply power to the second pump. However, as the vehicle reaches high mileage, it is not uncommon for fuel pumps to require replacement. This may cause the pump wires to run hot and melt or short out! We have complete return fuel conversion kits being tested on a pair of twin turbo 370zs.

Then my friends and I assembled it into a complete motor and dropped it back into the car. It is true I could have grounded the pump directly to the bulkhead, you can see I even put the new ground adjacent to an old stock one, but I wanted to supply a clean, solid ground directly to the pump without worrying about how electricity was going to make its way back across the tank, tank hangers, chassis, etc.

If the fuel pump is the cause, it means it can no longer regulate fuel pressure accurately and provide the appropriate amount of fuel to the engine. Attempting to start the car again, only to have it stall once more, makes it clear that there is some difficulty with the fuel pump. This occurs because there is less pressure in the fuel lines, and the engine is actually receiving less gas or intermittent streams of gas. Return fuel systems with the 350z come in a few variations. You could have hooked the new connection straight to the battery with a relay, take the power output from the factory fuel relay to use as the control signal with your new dedicated cable.

Are you going to do the turbo install yourself? Another signal of trouble may be at the gas station. I suffered a similar go, no-go condition this weekend. Damn I hope this works cause I can't stand not driving my vert. This has been a gradual problem. It should have been peaking at 4.
