    Ssangyong Rexton 2005 problem issue dead

    I've killed my beloved 2005 Rexton.
    I have obviously made a bad batch of biodiesel and the Rexton didn't like it. It initially started running rough - losing power - now wont start.
    I've had the glow plugs changed, the injectors changed, filters changed and fuel system flushed. She will turn over no dramas, and if I spray some sort of engine start/ether into the intake she'll fire up until I stop spraying. The system had a varnish like fuel in it.
    I'm thinking it might be the High Pre$$ure pump?. Totally lost as to what to do other than change the engine - ouch!
    I'm based on the Sunshine Coast - an hour north of Brisbane, QLD. Know of any fuel specialists in the area?

    Check for air in your fuel line first.

    Is it common rail? When you say it started running rough; over what sort of period - days- weeks - months? Can you check for fuel flow at an injector? It only needs two things to run - fuel and compression. If it starts on aerostart it is either not getting fuel or it has insufficient compression to combust the fuel. When you crank it over does it blow any smoke from the exhaust?

    Dont be too quick to blame the bio, lots of people who dont run bio also have their vehicles break down. you need to find someone who has or buy an OBD code scanner. this pugs into the engine management system and will, tell you if a sensor has died. They are not that expensive any more heres on for $145 MaxiScan MS509 OBD2 Scanner Code Reader Live Data | eBay
    Also dont be too concerned about vanish in the fuel system, it has most likely come from years of dino diesel, and every other rexton of that age will likely have the same amount of crap in the fuel tank and lines.
    Im not familiar with the rexton fuel system but I suspect that it has an electric lift pump in the tank. These pump should come on for a few seconds when you turn on the key, and when the engine is running and look much like the petrol fuel in take pumps found on almost every modern fuel injected car. Can you here a buzz in the fuel tank when you turn on the key? sometimes you can bash the bottom of the fuel tank and the pump will start working again if it is worn out or has crap in it.

    It sounds like fuel starvation. As its difficult to see if you have air in the fuel line when the engine wont run at all, you need to remove the possibility all together. Try gettign a really clean plastic drink bottle and cutting the bottom off it. rig it up so you can put a length of fuel hose from the nozzle of the drink bottle directly to the fuel pump inlet. bypass all filters and hoses. hold it up in the air, fill the bottle with CLEAN fuel (bio or otherwise, it wont matter) and give the hose a bit of a tap and light shake to make sure you have no air in the hose.

    now get someone to try to start the car in the normal manner. it might take a few cranks to fire as the pump might be empty, but if the problem is with fuel lines, fliters or pusher pumps, this will bypass the lot. It will also prove yuour pump is ok (if it is).

    Dont know a lot about your particlar pump, but most pumps have an inlet screen in the that may have blocked for some reason.

    its worth a look before you go spending big money. The first thing a mechanic will tell you is you have destroyed your ip using Bio. you wont convince him otherwise.

    If you do get the engine to run, try replacing the fuel hoses with clear plastic hose from bunnings which will show you if you have any air leaks, and where they are.

    I spent an enormous amount of heartache chasing leaks over the years, and finally bit the bullet and installed a walbro 10psi pusher pump near the tank.

    Good luck.
    Regards,

    Cade.

    Cade that wouldn't be a good idea on a common rail, injection system, as the injectors and pump are very sensitive to any sort of dirt, and some have an intake pump that pressurizes the fuel to 80 psi before it get to the main injector pump. its this "low pressure" pump is the one that i would check first. have a look at Diesel Common Rail Injection Facts 2 - YouTube

    yes it is common rail, It has a low pressure pump and a high pressure pump, From memory the pressures in the fuel manifold can get as high as 35,000PSI. It started running rough and taking longer and longer to start over a period of about a week. Until the final day when she would only turn over but not fire. I'll ask the mechanic about the smoke. Its currently at Cullen & Sons in Nambour (peugot and Ssangyong dealers). It was also at diesel power systems for a period, but it stumped them. Does that give you a better idea as to what the problem maybe? Do you know a friendly Bio mechanic or a specialist fuel mechanic on the Sunny coast.

    Thanks smithw - would this scanner be the same that the workshop has. The 'check engine' light on the dashboard did come on and I had it put on a engine scanner' then - it came back with so many codes they didnt know where to start. Its common rail, It has a low pressure pump and a high pressure pump-35,000PSI. It started running rough and taking longer and longer to start over a period of about a week. Not sure I recall hearing a buzz from a fuel pump. Do you know a friendly Bio mechanic or a specialist fuel mechanic on the Sunny coast?

    Thanks Cade - Do you think that would work considering the fuel manifold pressure is 35k psi - very high. Forgot to say to smithw that I do have the manual - its very good and tells me where everything is, just not sure where to go after changing the fuel, fuel filter, injectors, glow plugs - I'm guessing pumps? Do you know a friendly Bio mechanic or a specialist fuel mechanic on the Sunny coast.
