A stock FPR will work...so it's not mandatory to have an adjustable one... The AFPR just lets you have one more thing to tweek...

And yes, you should hear the fuel pump hum a little right before you start the car.
You can get the walbro 255lph fuel pump for around $100 from jsdperformance on the net. It's a drop right in piece, and only about $20 more than the stock replacement. good luck

You should only be able to hear the fuel pump when you turn the key to run w/o starting the engine (it'll turn on for a few seconds), or if you're standing right next to the back of the car while it's running.

If it's making a lot of noise (esp. a high-pitched whine) that you can hear in the car while the engine's running, it's probably about to die.

Well I can tell you that I spent a few hours at Zach's house today trying to get his TC to start...and it is definately a fuel pump issue.

First check that there was spark...there was.

Ran Codes KOEO and got 11 (imagine that ?!).

There was zero pressure at the schrader valve. At KOEO I never heard the FP run....humm, maybe on to something here...

At first I thought it might be the FP relay as it was clicking erratically there for a while but we swapped that out with a known good relay. I also checked the Inertia Switch to see that it wasn't tripped.

I pulled the fuel line off the fuel filter and placed in a container. KOEO did not produce a single drop off fuel from the line...oooops !

So now I am led to believe that perhaps a wire came off the FP during the installation of the new FP they did a few days ago ???

I think my last words to them were..."well guys...I have to go now while you drop the tank...again". [Image: rolleyes.gif] [Image: biggrin.gif]
