Did FPR shim, now check engine light on...

[ross3031]

So i did the fpr shim mod, put in the BB. Now my check engine light is on. Came on right after i started the truck after doing the mod. Double checked and everything is in right. Cant find anyone around here to read the code without charging me $80 for a full diagnostics fee. Anybody else have this problem???

autozone.. free code checks dont they?

Went to Autozone and they checked it and it came up as no codes thrown. The guy was pretty sure though that the scanner wasn't the right one for a diesel...

Lastnight as i was pulling out of a parking lot i shifted into 2nd, didn't get on the gas hard, just normal acceleration, then all the sudden it acted like it was in 5th going 20 mph. just started to chug and wouldnt accelerate, tried shifting into 3rd and did the same thing. Then after about 10 seconds, everything was perfectly fine. Went back to normal..

Any thoughts ?????????????????


Just to double check, there was no ball or anything in there stock correct. Just the fuel bowl, sping, and outer piece? Thought i might have heard something drop when i originally took it off but not sure...

The generic code readers at the auto stores won't read our trucks as they aren't OBDII compliant. How about filling out your location and maybe someone is close to you. I would read them for free if you were close to me. My bet is you knocked something loose. The lack of power could be the UVC harness on the drivers side, look where it comes out of the VC and make sure the connection is good n solid. Check everything , the FPR mod shouldn't cause a code. Take the BB out and see if it returns to normal?

You droped the spring cup. You are not getting enought pressure due to there not being a proper seal to regulate pressure.

The code is low fuel pressure.

Sorry, I didn't read you're follow up post where you dropped something, there is a good photo on the forum of all the parts laid out and how they go in. I would do a search for it.
