Z06 engine died
On July 4th, I was driving in Austin TX, outside temp was over 100 and my car died & would not restart. Engine did not overheat AND the car had 3/4 of a tank of fuel. Starter worked, but not getting fire or fuel.
Has this happened to others?

Where are you getting this from? I think it is complete nonsense and just giving misleading and bad advice. Please prove me wrong and inform us where you got the notion that this is a correct diagnostic technique.

Rail gauges push in the pressure valve, like a tire pressure gauge does. There is no need to remove the needle valve. If you remove the needle valve you run the risk of fuel spray.

Even with my permanent mounted electric fuel gauge you must also take out the inner rail needle for it to work as the sender also only screws onto the outer threads and nothing there to press in the needle.

My fuel pressure gauge I hook up to quickly check fuel pressure doesnt push in the needle as I use a long 2 foot AN hose with fittings to the gauge. It screws onto the outer (not inner) rail threads like a AN cap and inner needle must be taken out. It doesnt hardly spray anything when you relieve the pressure after cars has be sitting a while..

I forget what this does exactly but I have done this successfully to get my "other" car to start when having difficulties getting the motor to run on start-up.

The typical FP gauges you find at the parts houses will push in the needle valve. Mine does:

Definitely nonsense. Comes from the old carb accelerator pump days. Does not apply to a FI engine.One quick but not sure way to determine if it's a fuel pressure/pump issue is to remove the gas cap, put an ear next to the open spout, then have someone turn the key on. The fuel pump should run for 5 seconds or so when the key is turned on with the engine not running. Best way to check the fuel pump is to install a pressure gauge on the fuel rail.
