Top 20 2005 Dodge Neon - Page 2 Questions & Answers

something to do with a cam/crank sensor --either one or both are failing or a wiring / harness problem which can leave you stranded the sensors are not expensive if you remember the code you can look it up on line and find the explanation and how to change them

If it cranks good but won't start, Have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Check for applicable trouble codes. You need an obd2 code reader to check codes, yourself. Hopefully the code reader will check manufacturer specific codes as well as po codes. At the ignition coil and fuel injectors, dark green wire with orange tracer should be hot with engine cranking, use a test light to check voltage. If no voltage, that leads back to asd relay. I'm not saying the relay is faulty. The computer has to see both the cam and crank sensor signals before it will ground the asd relay, if either one of those sensors is faulty, the vehicle won't start. Just my opinion.

Blue smoke indicates that your engine is burning oil and at for your leak. Might want to perform a complete engine cleaning with a steam cleaner and determine where the oil leak is coming from.

Scan for fault codes to give indication of fault, re-check valve timing

releasing the gas pedal and it gets going again not very safe is the engine light on could be any faulty sensor in this engine diagram maf clean might help if a spark issue needs chasing it could be a fuel problem maybe bad fuel or blocked fuel filter

I think you mean relay, a relay is a device that is closed by a magnetic switch and that allows current to flow through the relay contacts to the device it powers. Think of it as a remotely operated on/off switch.

The brake system is a closed system, for this reason there are only two causes why there is no fluid on the reserve tank first there is a leak and second the brakes are wear out, if you already change your pads or shoes.you push back the fluid to the master cylinder tank, now if there is no a visible leak on the lines,calipers or cylinders,there is the possibility you have internal leak on the brake booster.

You're not giving much to go on. Is it a 2.0L or a 2.4L? You say it won't start. Does it turn over and not fire, or does it just sit there and do nothing when you turn the key? Both engines require you to remove the timing belt in order to change the water pump. The 2.0L is definitely an interference engine, and I'm not sure about the 2.4L. But if the timing belt was not re-installed properly, it will result in a no-start condition since the valves will not be in sync with the pistons and spark. Best case scenario you correct the issue and are good to go. Worst case scenario is that if the belt is out too far, you bent valves and have to service the head(s).

for the 2.0L engine, my info says bottom of engine, near crankshaft pulley.

Fuel Filter

A combination fuel filter/pressure regulator assembly is used, which is located on the top of the fuel pump module.Here's a link on replacing the fuel filter.

Could be a bad battery but I suspect your battery cable is either loose or corroded or dirty. Before you pull the battery disconnect your battery cables and clean them both ends and when you put them back on make sure you have good connections and tighten good.If that does not work pull your battery and get it tested at a battery out let . they should do that for free.

I suggest contacting the dodge dealership in your area and ask them

possibly running far too lean run the fault codes to determine the reason for the fault

There is no idle adjustment available. The throttle is controlled electronically. Idle speed is controlled by a air flow valve that acts as a by pass to the throttle plate.

Hi John, Im AL the owner of Big As Auto Repair. John, Low oil pressure can be many things. BUT, first you need to hook up an oil pressure gauge just to make sure its not the oil pressure sensor. If you have already put a new sensor on and it still has low oil pressure then you still need to check pressure with a gauge to make sure its not in the wiring or connector. If you find good oil pressure with the gauge then it need to be check to see why the pressure is low. It could be oil pump OR bearing issue.

Hi Donald, Im AL the owner of Big As Auto Repair. Donald, sense you have a burning smell and a starting and running issue, I would start by checking all the wiring and connectors to see if they are burnt OR may have fell onto the exhaust somewhere and melted the wiring.

Verify at least 12 volts at battery. Depending on car we could be dealing with a security issue with a light flashing, or a bad solenoid or starter. If you need further help, reach me via phone at https://www.6ya.com/expert/chris_b82b45c59bcf133d

turn the Key all the way back then forward one click push button under key remove key

depends how much , when and for how long All cars produce water from the exhaust on start up on cold mornings as it is water vapor and should be gone when the engine reaches operating temperature

Hello, There are a few different problem areas in your vehicle that come to mind as I was reading your complaint. I will go over the wire diagram for this neon and see exactly what we could be dealing with. Most importantly, I see your check engine light is coming on. If you can scan it while its on and get the codes I will be able to tell you pretty much exactly what is causing this jerking issue. Hopefully its a simple fix, could be under the hood, mechanical or electrical. Ive seen these pcm's fail in the past also. Advanced auto or autozone typically scans codes for free. Please Advise
