i desperately need your help for my hyundai sonata 2009 which fuel is lpg i want to know the exact plugs that should be used weather a long thread or short thread.because i always crank for like 30secs to a minute every morning before engine will start. fuel pump plugs have been changed but still.but a friend told me if the thread plugs are used it can also cause that please help
I have a 2011 Hyundai IX35. It had the same symptoms but no compression. It drove fine. Next morning would not start. Is lack of compression possible if as suspected the chain is loose and skipped ?
So my car is doing this lights and radio work but it’s no turning over like yours like the starting noise it just makes a click an stop. What could my issue be anyone pls help ?
i mean if the wrong plugs are used thats using a short thread plug instead of a long thread plug.how can i know the type and lenght of plugs to use for my lpg sonata 2009 model
I seriously doubt that it's the plugs that is causing the extended crank time. The reach on the plug and the thread length must match the cylinder head design so in my opinion the original plug design is in order. The only thing that may be different is the heat range of the plug since you are running propane. I have had limited experience working on propane engine systems. Most of the ones I have worked on used a vacuum fuel lock to open and allow the propane to flow to a mixer where it vaporizes but this system is likely different. Is it still using the gasoline fuel injectors? What brand of LPG system is this or is it factory? I would suspect your problem is fuel related, Give me some more information on the system and i'll try to help you.
@@PhillipBailey its factory and uses injectors i bought the car from a friend who kept changing plugs and says he cant really recollect the lenght of the original plugs since its been like 3years now
You could have a skewed temp sensor indicating to the ECM that the engine is warmer than it really is which would make it difficult to start. (like no choke) That is assuming the system is using the original ECM. I'd be curious how the computer is programmed differently to allow for propane. I'm assuming you are not in North America either as this is not common here but I understand it is in Korea and parts of Africa. I'd try to introduce some additional fuel into the air intake at the hose for the PCV at the air induction duct while having someone crank the engine on a cold start. I would use a small propane torch and a piece of hose. If it starts better this proves you have a fuel issue, (lack of enough fuel). Again need to know what kind of propane system it is using...
sometimes when the car is parked for like 2 days then trouble because it can take like 20minutes without starting though cranking alright unless you keep pressing the accelerator constantly before it will start
The fresh air hose in the middle of the pic at 1:43 into the video. Insert a small hose from a propane torch into the flex hose going into the throttle body on the right side of the hose...
A couple weeks ago was the first incident she was driving in the car all of a sudden died and I think she said it wasn't detecting the key fob so I replace the battery in the key fob and she would go to start it and it started when she put the key fob in the port in the center consul where the key fob can go into And the car started fine then there's been multiple incidences where the car wouldn't start, but if she got out of the car and locked the doors and unlock them and put the key fob in the center consul, then it would start. However, now it's not starting with the key fob in the center consul and I don't think it's a key fob because it's not saying that it doesn't detect the key fob but I replace the battery because it sounded like it wanted to turn over but the battery I thought it was a problem, but even with a brand new battery now it still won't turn over. Also, about a year ago in the summer I thought the fuel pump was bad but we ended up getting it towed to a mechanic shop and they said that the car just started and they couldn't determine why it wouldn't start before so I replace the map sensor and we didn't have any problems for about a year then about six months ago The car wouldn't start again and this guy took it apart, but I didn't think that he knew what he was doing so her boss put the car back together such as Aaron tag and things like that and it started. I thought it was the map sensor again but there wasn't any problems for the past six months until a couple weeks ago and I'm dumbfounded, and I have no idea what it could possibly be and it's not throwing any check engine codes as of right now either. So it was in a parking lot across town and after putting the new battery in it I tried switching the fuel pump relay with the horn relay cause a couple videos said that could be the problem. Unfortunately still not starting I went back the next day and thought maybe it was out of gas and maybe my girlfriend was wrong about there being gas in it. So I put a couple gallons of gas in it and then it started. So she drove it home I told her to stop at the gas station by the house and to fill the tank up so we would know for sure it wasn't a bad gas gauge, it only took 2 gallons before gas poured out so it for sure had gas in it and it's not a bad gas gauge. Then the next time she goes to start it, won't turn over. That's were I'm at with it. I've always thought when a fuel pump goes out it goes out, any advice you have I would appreciate it, I can't find anything online thats the same situation. Do you think it could be the camshaft sensor? Could a bad camshaft sensor cause the sort of state the car is in?
Wow! First and foremost when you say it "won't start" do you mean the starter won't crank the engine over or it cranks fine but just doesn't fire and run? There is a huge difference in the diagnostic process for each problem. Second, just because the MIL is not illuminated doesn't mean there are no codes in the ECM or other computers that could assist the diagnosis. You need to do a complete network scan of all the controllers and get a report of any codes together with the computer that is reporting the codes.
@jameskirk5403 no the exhaust cam was out of time due to a worn out timing chain. An O2 sensor can never cause a no start. The O2 sensors don't work til they get hot.
@@PhillipBailey is an electronic device in a vehicle's exhaust system that measures the amount of unburned oxygen in the exhaust. It's located in the exhaust manifold, which is connected to the engine and receives the air-fuel mixture from the engine cylinders. The O2 sensor works with the vehicle's electronic control unit (ECU) to determine the best air-to-fuel ratio for the engine to perform efficiently
if r.p.m not move when you start car = crankshaft sensor is damage . result the engine not work . I diagnose a non-starting engine by watching the rev needle r.p.m . Another things if no spark out from all spark this mean crankshaft sensor is damage .
Dud spray starting fluid into the throttle body after the maf sensor and if it fires that narrows it down a lot.. You are getting way wayyyyyyy to technical and its not neccesary
Thanks for the suggestion. I did use propane at one point. I would not recommend actual starting fluid as that can do damage to the engine. Try combustion chamber cleaner. Just my opinion...
My car is doing the exact same thing also what was the problem with it sir?
18:45 in video. Jumped exhaust cam timing.

Definitely a sign of a jumped chain is lack of compression. May also bend the valves if they contact the pistons.
So my car is doing this lights and radio work but it’s no turning over like yours like the starting noise it just makes a click an stop. What could my issue be anyone pls help ?
This one was cranking but not running. If yours is not cranking that's a much different problem. Check the starter circuit.

@jameskirk5403 but again it's not operational on startup. Has to be heated before it works. Has no affect on starting at all.

I diagnose a non-starting engine by watching the rev needle r.p.m .
Another things if no spark out from all spark this mean crankshaft sensor is damage .
Yes that works for most but not all. On some systems the gages stop working during crank event so you have to be sure. Thanks for the comment.
Why car wont start
Timing chain jumped
Your voice sounds just like George Clooney
Really?
You want to verify cam timing is right? Ok, hook up a scope to cam and crank signal wires. Boom, done

Pull the map flow sensor?
