The first thing I would do is check static fuel pressure (key on, engine off) and fuel system leak down—it doesn’t sound like this is something that you’ve done yet. If the system isn’t holding pressure, the issue can cause hard starting and vapor lock<\/a> once everything is warmed up. <\/p>\n\n\n\n
To check for static fuel pressure, hook your pressure gauge up, as you did before, then turn the ignition key to the “ON” position (don’t start the engine). Monitor the gauge for about 5 minutes to see if the pressure drops.<\/p>\n\n\n\n
If you find that the pressure does not hold, you may be dealing with a leaking fuel line, a faulty check valve, a faulty regulator, or leaking injectors. <\/p>\n\n\n\n
To determine whether the issue is a leaking injector or a problem elsewhere in the fuel system (i.e., leaking fuel line, faulty pressure regulator, etc.), install a fuel line shut-off valve in series with the fuel pressure line (or block the line in some other way). Run the pump so that there’s fuel pressure, then close the shut-off valve. <\/p>\n\n\n\n
Should you find that the pressure still leaks down with the fuel pressure line blocked off, you know you have an issue at the fuel rail, such as a leaking injector<\/a>. On the other hand, if the pressure now holds, the problem is elsewhere in the fuel system. You may be dealing with a leaking fuel line, faulty check valve, or bad regulator<\/a>. <\/p>\n\n\n\n
C6 Corvettes are known for having the fuel pump fitting on top of the tank crack, which is a possibility. So, keep an eye out for that. <\/p>\n\n\n\n
Also, unfortuantely, I did not find any videos attached with your question. <\/p>\n\n\n\n
