Default Mechanical Help?

Hey guys well im planning on driving across country with my 2003 Express. 4.3lt. within the past 4 months ive changed:
Fuel pump
fuel relay
fuel filter
spark plugs
spark wires
rotor and cap
injectors Spider.

Now i am getting 2 codes which is p0420- Bank 1 Cat 1 because i had raw fuel go in the cat. (eff me) and now this code popped up P0006. -Fuel shutoff valve "A" control low. Anyone know what to do?

the cat may need replacing. Faulty emission parts will cause incorrect data to the ecm....which could result in other issues.....
The fuel shutoff. Did you perhaps damage wome siring when working on the spider? It could be as simple as that. Otherwise I have read that you may need a shop sized scan tool to properly diagnose the p0006 code. Had held readers are sometimes not enough.
