Would you think it would be the throttle position sensor on the CP3 pump?

Correction on the last post. Fuel injection sensor on the CP Pump.

Got a tip from a buddy of mine the other day that he had the same problem with his truck. He told me that he changed the fuel pressure regulator and it fixed the problem with this P2121 Dead Pedal problem. Just changed it out today, so we’ll see soon if this fixes the problem with my truck. I’ll keep y’all posted soon.

Fingers crossed
Did it work? I also have this issue and I’m about annoyed with it
Found out that the previous owner tried to change the pedal accidentally pulled some of the wires out of the pigtail that plugs into the pedal assembly. Once I pushed the wires back in it’s been running good since.

I’ll have to check mine. I know the clips for the pig tail are broke and have been since I owned it. I wrapped electrical tape around it to keep it plugged in. Could still be moving though
Another thing I found was a wire from that same bunch was grounding out on the steering column.

I’ve always thought mine was a ground issue. I’ll try something. The code won’t come back for weeks and then one day it’ll come back
Drove me crazy too!!!! I was ready to trade in my truck, but I barely bought it in December. Would’ve been really upside down!!!!
