Passenger side bank not "firing"
I started my 97 F250HD today to get it inspected. It has been sitting about a month since it was last run. It was very hard starting and kept stalling. I checked the oil and it was a little low, so I topped it off to make sure I was getting plenty of flow for the HPOP. Tried again and the same thing so I pulled out my vin locked superchips "scan tool": the dreaded P0344. Off to town to buy a pair of CPS's, one for the truck and one for the glovebox.
I installed an aftermarket CPS and put the new ford unit in the glovebox. The same thing is happening, super rough idle and no power.
Here are the things I checked:
-HPOP oil is topped off
-Valve cover harnesses appear to be okay by resistance check
-When idling I can pull either or both of the passenger connectors with no change in running condition
any thoughts? I am planning on checking the fuel check valve I have heard of that goes from the bowl to the passenger bank of cylinders and also looking closer at the harness.
