Need rail pressure help
Ok every thing was good the other day. I unplugged my TST now my rail pressure is 25k@idle. All the fuses are good. Any ideas I'm not currently close to my truck so I can't check much out.

if your FCA isnt plugged in it will default to the max position so check the connections
|
Must sound like a rattle can! I second the FCA on the back of the CP3 pump also check the rail pressure sensor. Not sure if that would do anything ?
|
I checked the connections and they were all good. I'm wondering if something came unplugged from the dual pump controller box.
But thanks for the input I'll double check the connections as soon as I get back. Other than something being unplugged could there be something else? |
if something at the dual pump box is unhooked it would cause the same problem. it could also be a stuck FCA.
|
I third the FCA. buy it from Cummins its a lot cheaper.
|
Thanks for the input I will recheck all the connections and fuses when I get home hopfully it's something simple. But with my luck I'm almost sure it's not
