I posted this the other day on the performance page but didn't get any hits. I started my truck up the a couple of days ago and the check engine light stayed on. I checked the codes and got the P-0193 code. It seems to be running alright but I did not want to drive it until I figure out what is causing it.

I installed the Quad rail gauge and I think it may be in the conection to the rail that is causing the problem but have not had a chance to check yet. Any help would be great. Thanks.

Its indicating your fuel pressure sensor voltage is too high.
Maybe recheck the connections.
