i have a 2004 ram 2500 i am replacing the fca and rail pressure sensor are there any precautions or tips you can help me out with, do i have to relieve fuel pressure inthe system before i change these parts. thanks in advance

 

no, a lot of people have difficulty getting the screws out.
use a 1/4" ratchet with a 1/4" deep scocket with the correct torx bit to crack them loose, be sure the "CORRECT" bit is all the way in the screw before attempting to loosen, tap it in.

 

Lots of recent posts about the 3 Torx screws on the FCA. Madhat (admin) says he used some small bar stock (I believe it was) to tap the sides of the screws to help loosen up the loc-tite on the threads.

Rail pressure sensor......self-explanatory. Unscrew old sensor, screw in new sensor and plug in wiring harness.

 

ordered the fca and a new fuel rail from genos came with pressure sensor and fuel limit is it a pain to change the rail out thanks again

 

no but it is easer just to change the sensor.

 

it would probably take a half hour tops to change the rail, a couple minutes to change the sensor.

 

Be sure to use brake parts cleaner and douse around the sensor and the fuel control. The less dirt contamination, the better.

 

replaced the fca truck started but ran a little rough then it threw code p0088 im going to change the fuel pressure sensor see if that works do i have to relieve the fuel pressure when i swap this out if so how would i go about doing that. Thanks sorry for all the questions just cant afford to pay the mechanic any more

 

no worries, no pressure is held in the system.

 

changed all parts still get p0088 code high rail pressure had mechanic friend over seems to think it is a bad injector when it started had a loud knocking we cracked open injector #5 fuel line and it quieted down so i guess the next step is replacing the injector

 

do you know what the rail pressure is?

it should be 5000# at low idle

 

no the scanner he had could not read the fuel pressure

 

i went to a friends shop, it took him 2 minutes to get his latest and greatest Snap On scanner to read mine.

i put in a gauge after that.

 

Did you ever get your p0088 code fixed? I'm having the same problem. Interested to hear what the problem turned out to be and how you fixed it.

 

Here is another example of poor troubleshooting and a lesson to be learned. Shot gunning parts is only good for the parts vendors
