ok i pulled the rail sensor and turned the key on and there is no fuel commin out
shouldent it shoot out of there?

fuse ok.
how do i check if the sensors gone?
ok on the live link the fuel pump volts are at 7.5 and the injector psi is only 9.2!! wtf?
codes are p0193- fuel rail pressure check high input.
p1233- fuel pump driver mpdule disables or offline
p0148- fuel delivery error
Did i blow the module?

yea fuse is good! i jsut checked one of my other data logs and during idle i was at 4.4 f/pump volts, and 39psi fuel pressure.. and now its 7.5 and 9psi... so the fuel pumps are on and working.. the fpdm is telling the pumps to run... working? but there is really low fuel pressure? im thinking that stuped hose for the ppvr delete came loose??
Maybe the FRPS? Fuel Rail Pressure Sensor. They are known to blow if you hit the rev-limiter several times. Sometimes all it take is one time. Do a search for "FRPS" or even spell it out and search for how to test. Hopefully you'll get this resolved soon!
if the sensors gone then why does it read 10 psi and the autometer fuel gauge reads zero?
Does the pump cycle when the key is turned on, if so how long?
Pull battery cable off and retry, this will kill the code AND ADAPTIVE LEARNING.

they run yes and about the normal time.. i tryed reseting the batt did nothing the coes came back.
Ok, that is the idea, to make them come back. Did you check the connector in the driver side truck for connection?
Sorry to make you do alot but i am not there to inspect
When you pull the vacuum hos off the frps does it smell like fuel or have fuel in the line?
This is the order i would check things:
1.replace fuse under hood
2.check frps for smell and proper connection
3.check the fpdm for proper connection
4.check roll over switch, make sure it did not trip
5.undo battery to see if codes return
6.check fuse for kenne bell bap, and if installed correctly, plus upgrade fuse to 30 amp under hood.
7.pull tank and check all fuel lines for proper install
The p1233 code i usually get when the fuse is blown, fpdm bad, or fpdm is not connected, or frps bad,fuel line undone

i have done and checked everything but removing the tank
everything looks fine and all tests out ok. the wierd thig is that it will run.. but barly. computer says there is only 10 psi. if you rev it past 1400rpm shes runnen out of fuel n dies.

if you can hear the pumps running then either the pumps are bad, not likely both pumps are bad, the fuel line to the top hat has come off or is split, most likely cause from your descriptions, or there is no fuel in the tank.
yea i put some gas in it just to be on the safe side. So i know there is gas in it. its gotta be that gates fuel line used to remove the ppvr? i really dont wanna drop the tank again.
