Whats it mean when the same code pops up twice? I am geting a 42 again. But it says 42 twice.

This is the PCM things for 42.......

1)MFI relay (ASD relay) control circuit Harness and connector / MFI relay (ASD relay)


2)No MFI relay (ASD relay) output voltage at PCM Harness and connector / MFI relay (ASD relay)


3)Fuel pump relay control circuit Harness and connector / Fuel pump relay.

What the hell do these mean? What does the fuel pump relay do? And where is it? I get plenty of fuel pressure so my pump is fine.

The connector/harness might be loose. The fuel pump relay one of the little squarish black boxes right behind the brake fluid reservoir (it's the one nearest the reservoir.

I have checked them already and they seem fine. They look a littel nasty though when I take them off and look inside them. There is some kind of white paste in their.
