The car has not bee up and running on the street in about 2 weeks but I have been running in the garage and assume that would be enough to see or smell gas there if it were present....right? Since the regulator is $50-60 at autozone and needs to be ordered I did not just go ahead and replace it yet. If you have any other ideas I would be very happy to check them as I said before I am just running out of ideas. I will probably stop on monday and order the regulator or try to find one in stock somewhere.

Yeah, the fuel pressure regulator can be expensive. The adjustable FPR like the Casper I have costs alot more.
If the diaphragm is ruptured you will most likely have fuel in the vacuum line from the FPR to the throttle body. Are both the fuel pressure and return lines to the fuel injectors rails OK?
Out of curiosity what is the fuel pressure reading at ignition to on but engine not running. This is the fuel pump prime mode which lasts about two seconds.
Another way to test the FPR is start the engine (hopefully you can keep the engine running long enough). Record the reading. Then disconnect the vacuum line at the FPR while engine is still running. Put your finger over the hole on the disconnected vacuum line when you do this. Observe reading. If the difference between the two readings is greater than 7 psi then the FPR is bad.
