Have you checked the fuel pressure yet as others have already suggested?

Yup.

And before I bought a fuel pump, I'd ensure thre was 12V going to it. My wager is still on a problem with the electrical connectors/pins to the relay plate. I noted before what I did to resolve the same issue...

Replacing the fuel pump might fix it, and then it again it might not.

so I just checked with my friend and he said when I was turning the key there was fuel pressure and he could tell fuel was in the rails

so I guess it is not the fuel pump

is there an ECU on this car - the reason I asked is there is a box behind the batter that looks like a electridle unit - could the problem be in there ???

How did your friend know there "was fuel pressure and he could tell there was fuel in the rails"?

Has your pump been updated or still have the 3 port in the back ?

Checking for fuel in the fuel rails isn't the same as checking the fuel pressure. To rule out the pump or the fuel pressure regulator you need to know what the fuel pressure actually is.

JP, You can pick up a fairly inexpensive fuel pressure gauge at AutoZone or Pep Boys.

Also pick up a couple of small hose clamps and insert it permanently inline in the supply line - somewhere you can see it in the engine bay

And, I had this happen, the fuel pump ground must be secure. A loose or poorly crimped ground will stop that pump.
Common on ‘75s where there’s a chassis spade for the ground.
