    Sorry guys since my cars been down its been rough haven't had internet. Current symptoms. No fuel! Car was running with old furl pump but not enough pressure whole new assembly and now no gas. The solenoid is quit loud under the hood? Swapped that as well. Also intake hose swells almost as if catalytic converter is clogged. Yet I pulled an upstream o2 and no change. Going back to old fuel pressure regulator on new pump.

Got 2000 dodge neon will start when cold run good but when motor warms up won't start


Nikki is the engine light on, are there any codes,have you had a tune up or any other work done lately.when you say it won't start when warm(do you mean engine will not turn over, or does engine turn and refuses to fire.
If I had to guess failing fuel pump, they tend not to build fuel pressure when ran a while(warmed up) and when left to cool build somewhat better pressure.

2003 Dodge Neon Code P0551 and Rough Idle


This is either the sensor or an open/shorted circuit leading to the sensor, you need to use a dvom to check it or replace the sensor and atleast eliminate that fault

My plymoth neon shuts off when i stop at lights for a long time or a short time but it starts right back up what is it i was going to replace the fuel pump but i dont want to if that is not the problem


I dont think it would be the fuel pump, or else no fuel would to delivered to the engine.
i would try cleaning the throttle body first, as dirty throttle body's can cause rough idling and stalling while stopped or slow speeds.

2003 DODGE NEON RUNS ROUGH


Try cleaning the EGR valve first



electronic Tempture Control
ECT sensor
symptoms
Potential Symptoms

Symptoms of a P0118 could include:

* Very poor fuel economy
* A no start condition
* Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
* Illumination of MIL
EGR valve

Usually a fault in the control circuit, will leave no noticeable symptoms other than the Malfunction Indicator Lamp (MIL) illumination. However, if the EGR control solenoid
is stuck open due to debris, etc. the code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether.
