2001 dodge victory plus shows a no bus code sometimes it will start but then wants to die I got home and pushed the fuel valve no pressure what to do any answers

check the fuel rail for fuel and pressure, also can you hear the fuel pump running with the ignition just on should start pump for up to 30 seconds and turn off until pressure is reached. should hum.

check the fuel pressure and flow, if the flow is low check fuel filter.

check for codes in the PCM if none the I would check fuel pressure and volume. the volume should be about 1 pint in 15 seconds. the fuel pressure should be 35lbs, continually check pressure until the car dies as sometimes a bad fuel pump won`t show up immediately. also change the fuel filter.

What color wire was loose ? VI/YL - Violet with yellow trace . A no bus message means the instrument cluster lost communication with the serial data network . Do you know what that is ? Gauge info. comes from other computers on the vehicle through the data bus. If a module (computer ) looes connection some how , faultly module , wiring problem etc... this message will show an more then likely a DTC - diagnostic trouble code will set in one of the modules on the vehicle . Don't know how much you know about this stuff , but you can not go to a auto part's store an have it check for code's . The tool they use doesn't check all the computers on the vehicle . The data bus on your vehicle is the PCI bus. 006 Chrysler PCI Communications

Reading as much as you can about this an finding wiring diagrams to test the bus wiring plus having the modules checked for communication network code's is the way to find a fix . Most of the time it is a loose connection that causes this problem .

lift hood and look for your main fuse/relay box. open. look on inside cover for placement of the AUTO SHUT DOWN [RELAY] try to swap the relay out with another from ...the HORN or WIPERS if the relay looks the same. that sounds like why your vehicle is not starting.

you have flattened the battery ,now charge the battery for 24 hrs then it will crank ,if it still doesnt start then check the fuel pressure 55lbs on the common fuel rail their is a tyre valve ,connect a pressure gauge to this valve and see what you read

sounds like low fuel pressure - check pressure /gauge. if not in specs -replace fuel pump/filter assy.

with a problem like this you must surly have a check engine light on ?
To answer your question yes an EGR valve could cause this problem on a hemi ! But would act up more cold .
And No the key thing wont work on this year of vehicle , you need to have a scanner for OBD 3 to retrieve the codes .
This sounds like a fuel problem to me have you checked fuel pressure ? and for a tuneup , remember the hemi takes 16 spark plugs it could have some of them miss firing .

check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

if it starts runs and dies instantly, the fuel pump could be the culprit, its getting the signal to sqirt fuel to start but then no voltage to continue pressure.. check fuel pump and also worse case senerio is the ECU (main computer could be bad)
