I have a 1997 interpid sport 3.5l With these codes P0175,p0300,p0302,p0304,p0306,p0171.

I have replaced spark plugs ,spark wires, O2 sensors, coil pack, fuel injectors, Battery.

could it be one of the following?
map sensor bad?
camshaft sensor Bad?
Crank Shaft Sensor bad?
Fuel pump?
Timing belt?

 

Any help would be helpfull..... I am to the point of pulling the motor and rebuilding it.

 

to me, codes really mean nothing without symptoms, data stream information from the scanner. you could have bogus codes from something getting unplugged while the key was on.

I never 'fix' a car based on just the code. that'll lead you down the wrong path and cost too much time and money. a code is just one small segment toward proper diagnosis.

 

I think i found the problem. i have fuel running out the vacum line that goes to fuel pressure regulator. so i think the fuel pressure reg is bad.

 

that's great and see how something really unrelated to all the sensors and computer caused erroneous codes.
