Re: 81 c30.....5.3

Now check the pink wire at the White color coil connector on each bank. Also check the pink wire on all of the injectors,

Then check the dark green/white wire in PCM Red connector Cavity 9 for the fuel pump relay signal. The PCM outputs a + signal on this wire.

You should use a Digital Multi Meter when testing circuits on a fuel injection harness. You could damage the PCM if you are not careful.
