in the engine compartment where the Ebox is,can you put your hand down by the heater box and feel for moisture,we have had occurrences where the drains don't work and water stays in that well and corrodes the soldered joints. also you may want to try an overlay from the fuse in wiring diagram to the relay (fuse in ebox that is),if it runs fine with the overlay then you probably have moisture in the wiring.
Thank You for all the help & quick response, Im on the road for the next couple of weeks & will check it out once Im back & reply back. Do you see a problem with me just rewiring the pumps to come with ignition? Thanks again for all your help.

yeah you can't do that,pump 1 comes on for 20 seconds and then pump 2 comes in which is controlled by ecm,you may well have fuel pressure issues with them both running constantly. i am pretty sure the overlay will fix it either from the fuse or ecm wire to relay is faulty, lets see if this fixes it and then we can go from there as to the repair.

Hi Rob: Hopefully this hi-res pic is easier to read. double click on the pic to enlarge it. Let me know if you need anything else. Are you back in the GTA?

Thanks peter, I just fired up my old workshop manual found the cd, not back in gta yet, hopefully soon!
Not sure why this code popped up all of a sudden, seems like I always have the worst ones pop up!

my car threw the p0203 malfunction in relay, but it ran did not stall out.
I ended up doing an overlaywire from the ecm to the relay,
pin number 65 X00460 on ecm-bank 1 .035 GU [green with blue strip] was bad, ran the new wire to the back of the relay, ran it thru the interior.
This is the 2nd time I had to do an over lay first time for the o2 sensor on the same ECM bank 1.
This over lay stuff is a pain in the ***.

I have a problem with 2010 flying spur speed. It stalls after 20seconds. I pulled relay for pump a and car runs fine but I get fuel pump shop message on dash. No fuel related codes before I removed relay?
