Do you have a hand held tuner or HP Tuner installed on a laptop? Wondering if you could look at the fuel pressure that way...maybe even trend it. I have an interceptor gauge on my A-pillar that reads all the computer parameter via the OBD-II port and fuel pressure is an available parameter.

Take a look though. It may save you some time.
Good luck..

Well technically it IS an available parameter, but there's no sensor anywhere on the car to determine fuel pressure. GM should've put one somewhere on these cars but they didn't unfortunately

I'm going to check it as soon as I can. Hopefully it's something simple like a bad regulator.

97TA you said it doesn’t change no matter what fuel jet?
Are you getting your fuel supply from the fuel rail?
And I need to know the exact placement of where the wideband is in the exhaust.
If the fuel pump is laying over, you pull fuel supply from the schrader valve on the rail, and if your o2 sensor is on the passenger side then all those cylinders are experiencing a lean condition most likely.
Downfall to o2 sensor dependency for datalogging is its always an average off the all the cylinders that’s putting exhaust flow across it.
You can learn a lot more about what’s going on with your engine while making a hit, immediately shutting the car off at the end of the pull and removing the spark plugs.
All cylinders could be lean, might only be one going very lean or completely dead on fuel. Like I said, the o2 sensor is only seeing an average of whatever cylinders are putting exhaust across it.

There's a bunch of fast cars in the area. Do you have a Facebook? If you do then you need to add "Wolf TL" He knows all about the street racing scene in north Alabama. There's a few guys here that should run low 9s, high 8s in a quarter if they can get their **** figured out
