P0193 after injector replacement

[OnTheFritz]

Got injectors replaced, from LDS. And did the Cat filter swap on the filter head. Went to start and I got a P0193, long cranking before it will start. FRP is 26.1 and DFRP is 5.8. Runs really rough, afraid to let it run more than a few seconds. No leaks that I can see.
I thought I had injectors hung open, so I changed them. Truck has 208,000 miles, so they were getting up there.

If your rail pressure is higher than desired the regulator is letting the cp3 run at max pressure.

Like mentioned. Your fpr sounds like it’s either unplugged or bad.

Like zach said, you probably left the FPR unplugged.

Lauren told me you called yesterday Duane. Sounds like you don't have the FPR plugged in.

Did the same thing on my lb7. Took it to a shop and everything. Ran horrible. But was just unplugged. Needless to say I felt pretty dumb.

FPS was unplugged, but it is still acting the same with it plugged in. Could it be the FPS was bad all along? I don't see anything else wrong.
Thanks everyone for your help.

That could very well be it as pig as the wires are in tact and nothing is grounded out or broken.

I'm an idiot. Lol the fuel rail pressure sensor connector has a wire pulled out of the connector. Now to find one.

Great to hear!

New connector on, truck runs great!
