Code PO174
Hi guys,
Got a problem.....have a 2001 Blazer 4.3 and in the last 4 weeks I've had the fuel pump replaced twice. The first one may have been faulty....don't know that for sure, it's what the mechanic said. Just picked it up with a new AC Delco fuel pump and drove it 2 days when suddenly the check engine light popped on and I checked the code and the code number that came up was PO174 - System too lean, Bank #2.
Where do I go from here? Any help would be greatly appreciated. Love the truck and want to get it right.
Thanks
Phil
