Correction:

Alright hopefully this is the right way of posting it, But issue Im having is the p0192 , Kept erasing the code and didnt think of it.
On thanksgiving day gave it gas and then boom car went into limp mode got it into parking lot.. would idle rough for 10-20 seconds then shut off.... Ordered the sensor(which wasnt bosch but was proper part number) starts up but want to hold.. HFPF drops after 15 seconds.. then shuts off

So my question is, I know what the correct part number is (thank to dinner and chimii post from looking)

Where am I able to get the actual part ...local wise or fast quick turn around time

if this isnt right way lmk. Thank you.
 
What does the accessport actually read for your fuel pressure? Sometimes you can get a 192 for having a bad fuel pressure relief. A datalog of you trying to start the car would be beneficial here.

Here’s a way you can test it. Disconnect your spill valve electrical connection and turn the vehicle over. If it runs, you’ll see something like only 40psi of fuel pressure (maybe up to like 80 on cold start, but suffice to say it’ll be concerningly low).

If by disconnecting the spill valve your car runs fine, it’s the relief valve. As an aside, you can drive the car without the spill valve connected, do that at your own peril, but do NOT go into heavy boost or high throttle or rpm.

Your discretion, but I’d say test it at your earliest convenience. Fuel relief problems commonly get confused with fuel sensor.

heard will test in morning. even with the code popping towards that sensor but im guessing that code could be like 3-5 things correct releated? but here's the question should I put back the original sensor back in when I test it or one i picked up in 074?

For the purposes of the test it won’t matter too much. Without a spill valve, the car won’t run at a pressure high enough that whatever sensor is there will have any issue reading.

So got around to it...try to start..(been working) start and just die....nothing moved on the hpfp on Cobb at all


Right now only code is p0091 fuel pressure regulator 1 control circuit low

Yeah, that's a spill valve code (which presumably you disconnected). It should definitely still run though, even without the spill valve. Case in point, see attachment.

If I still lived in SoCal I'd just drive to you to help you out lol, used to live in Oceanside. This is pointing me more towards it being you FPR, and I'm almost positive of it at this point given everything you've said and we've spoken about. I suppose I should still say take that as my best guess, not me telling you it definitely is, I just *think* it is. You can try to wait for more people to weigh in though. FPRs sure ain't cheap.

Well the part you'd replace is actually the relief valve on the side of the fuel rail, not the spill valve itself or HPFP.

Those guys. You can pull one off of a CX-7, speed3 or speed6 from a pick n pull as well.
 
Have a valve should be here Monday also with the sensor... Guy had one and had it sent to me asap...so let's see what happens
