SOURCE: diagonostic trouble codes reported p0171

P0171 is system too lean bank 1, P0174 is too lean bank 2, and 302 is misfire bank 1. Look for vacuum leaks. If you don't find them, put a vacuum gage on it can check. The P0171 is almost always a vacuum leak. If not other possibilities are front O2 sensor is too old and should be replaced (if mileage is greater than 100k then replace). Try injector cleaner. Misfires are usually bad spark plugs, but could possibly be caused by insufficient fuel. I've never had a car of mine in bad enough shape to have that error.

Look on the passenger side of the intake at the rubber elbow attached to the big black plastic tube and then to the intake manifold. Make sure it is not sucking shut and maybe a small hole in the bottom of it.

SOURCE: check eng light on codes p0171 and p0174 what do

If you do not find an obvious problem in the vacuum hoses or PCV connection, I would sadly suggest you prepare yourself for a new lower intake manifold gasket. Those two codes combined indicate that the leak is not in one spot, but across the rear of the intake. This 4.2 V6 is known for this failure, and many TSB's have been issued regarding it. If you don't want to spend hundreds replacing sensors and getting your ECM rebuilt just to have a truck you cannot get inspected, spend the $90 for a smoke test on the vacuum system. I wish I had done that two weeks ago. I will be changing the gasket this weekend.

Dose this mean computer die?wont start new fuelpump so where do i go from here ? new computer or what


Take it to a ASE certified repair facility ,they'll fix it up ! Don't just replace parts !!!!!

P0171 - is a lean code bank 1 -possible vacuum leak , low fuel pressure , plugged fuel filter ,
P0300 - is a random misfire code which is understandable with a lean code .
P0420 As the code description implies the P0420 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0420 code is combined with other codes, try fixing the other codes first
P0452 - EVAP Control System Pressure Sensor Low Input
P0446 - Evaporative Emission Vent System Performance
P0453 - Fuel Tank Pressure Sensor Circuit High Voltage
P1639 - PCM 5 Volt Reference Voltage Circuit Condition
P1653 - Power Steering Output Circuit Malfunction
P1651 - Fan 1 Relay Control Circuit
If you don't know what your doing take it to a repair shop before you waste your money ! You have a lot of problems here an I don't think the computer is bad , I'd say lack of maintenance ! You need to learn how to test thing's to fix them ! From the five volt reference voltage code , I'd say one of your sensors is shorted internally bring down the ref. voltage circuit causing the no start, but then again the 5volt ref. circuit in the PCM could be the problem . What you need to do is Disconnect all sensors that receive 5volt ref. signal one at a time an see if it will start . If I knew what year vehicle yours is I could tell you what sensors ! MAP, TPS , etc...

Car cranks but wont start


The most common cause is a vacuum leak. Check all the hoses to everything. The 171 and 174 error are lean warnings on the engine. The 440 and 453 are evaporative emission control leaks. There could be a hose loose that is causing all of this.

they are all emission faults

P0453 OBD-II Trouble Code: Evaporative Emission Control Pressure Sensor High Input. P0453 code means that a reading from the engine's evaporative pressure sensor is higher than normal due to fuel tank vapor leaks into the system.

saturated carbon canister
sensor faulty
rubber evap hoses at the tank perished

idea
check the tank fuel cap seal is working
replace the cap is one possible cause

check the fuel pump pressure or for injector rail leak
P0446 Evaporative Emission Control System Vent Control Circuit Malfunction. The code P0446 is set when the engine computer recognizes a fault or restriction at the vent control part of the Evaporative emission control system (EVAP).

The Code P0452 indicates that the Evaporative Pressure Sensor is indicating pressure change values that are below specification, during the EVAP Monitor test and/or the operation of the vehicle.
