  • Fuel System Failure

    Hi

    I have a 2010 GX diesel which has recently started to go into limp mode and displays an error code on the Scangauge of "P0093". The description of this code is "Large Fuel Leak". The first few times it happened, I was able to stop and restart the engine and all was well. I would then clear the fault code on the Scangauge.

    Last week it happened again and I stopped and restarted the engine, continued driving and then it happened again after about 100 metres. No amount of stopping and restarting would get it out of limp mode. I had no choice but to put the car on a tow truck and get it to a Toyota dealer.

    I just had a phone call from the dealer saying that the fuel pressure was lower than expected and that the fuel pump, injectors and common rail assembly need replacement. They haven't yet removed these parts so they are unable, at the moment, do say what caused the failure. They have quoted $4.5K for parts and $1.1K labour!! I'm now stuck between a rock and a hard place. If I don't pay, I have a hunk of metal which is of no use.

    Has anyone heard of or experienced this type of problem? Does their diagnosis and prognosis seem plausible? I realise that it's out of warranty but surely such a catastrophic failure should raise doubts on the "marketable quality" of the vehicle.

    I will be contacting Toyota in an effort to get them to come to the party financially. Does anyone have a contact who may be able to help me?

    I'll keep the forum updated.

    Sorry to hear about your situation Mike ,some more deals would be helpful.

    Is it chipped if so which one, do run a secondary filter.

    Cheers

      If the rail pressure is down, to about only half normal pressure at cranking speed, you will have little chance of actually starting the engine. I had the same problem with my work ute, a 3.0 litre common rail nissan GQ. I first noticed that it was cranking over more and more times to start up hot. Then i could only start it cold by jump starting , by running it down the incline where it is parked. Mine had only done 106k, just out of waratee. I paid over $6k, inc labour to fix the rail problems. New injectors, and recon the pump. Fixing these pumps and rails is specialised stuff, only 2 places in Adelaide as far as i could find, that can do the job. I have now fitted a Staindyne filter to my 150, and the Ute. Water is a bad bad thing in common rails. I only ever use BP Ultimate fuel. (except rarely when away and no BP.

        Yes, I forgot to mention that it has a DP Chip but the problem occurs with or without the chip connected.

          I think Dpchip have a engine warranty I would be contacting them as well.

            How do they know the pump and the injectors are the problem? Could just be the relief valve in the rail. Rather than try the cheaper fixes they seem willing to do a more "thorough" job and the result is no comebacks for them although it costs the customer $6k to get the car back. If it was my car I'd replace the rail first, if that gets it running then hook up the techstream and look at the rail pressure and injector feed back values. Seeing as the ecu isn't throwing any other codes than P0093?

              Before i sent my GQ in for actual fixing, i had a full diagnostic testing done, on rail pressures, and other stuff. I got all the tests printed out so i could see what was actually happening at different RPM, motor temps, ect. Think that would be a good start point, as yours sounds like it is running ok , before the limp mode cuts in. If rail pressures are getting low, hot starting will be the first to be taking more turns of the motor before starting, then as problem gets worse(doesnt take many more KMs, cold starts will get harder to.

                Is the DP Chip one of those where the relief valve is shimmed? If yes look there first.

                  Hi,

                  I'm only new to the forum and by no means an expert and I'm sure I will get shot down in flames but I read this and while I feel for you and your 5.6k problem, I also have to wonder why you went against Toyota recommendations and chipped your Prado and now that you have an issue (and it's out of warranty) you feel Toyota should come to the party? I just bought, in January, a face lifted 150 and I got them to quote all the accessories I was going to add, ARB bar, Snorkle, winch, chip. They quoted my on everything but the chip, on this they said they don't recommend having it fitted as if I have an engine catastrophe it may nit be covered. I did this and then got the part minus the chip done myself so they could say down the track something's failed due to me fitting so and so. I didn't get it chipped because in my mind I don't want the hassle and if I needed more power I would have bought a car with more power. Now I don't work for a dealer or have any affiliations with any but having worked in the aftermarket I've seen guys go against advice and then expect to be bailed out when it turns to crap?

                    Might be a stupid question , but i assume that the fuel filter has been replaced as part of the diagnosis? if it is blocked you can get the same fault code or if it is sucking air

                      I do a fair bit of work on new Isuzu trucks and that description on a truck usually means blocked fuel filter as
                      Bear63 has just suggested. I would highly recommend you get it checked also check where you are fueling up, is it at the same station every time?

                        Good reason to change that under bonnet filter more often than Toyota requires and use fuel that comes with a warranty e.g. BP

                          After a lot of arguing with the dealer, I now have the car back and it is being transported to a reputable diesel mechanic. Dealer wanted to charge me a restocking fee of 10% ($450) for the parts that they ordered to "shotgun" the repair. I got out of it for $300 but that still irks me. The one positive to come out of the dealer experience was that they washed the car before giving it back. Expensive car wash!

                          To address some of the comments in this thread:

                          I have always used BP diesel from the same servo (where possible).

                          I haven't installed a secondary filter but I will certainly look at that option.

                          I haven't had any starting problems nor any performance problems at all to indicate low fuel pressure.

                          DP Chip does have an engine warranty but it exists only when the vehicle is under warranty. The manufacturer's warranty has expired.

                          The DP chip is purely connected in series with the injector connection. There is nothing done with the relief valve.

                          The fuel filter was replaced at the last service which was about a month ago. I don't believe it was changed by the dealer as part of his troubleshooting procedure.

                          I chose to add the chip to give me more torque to tow a 2.5 tonne van. Sure I could have bought a 200 series but I considered the chip to be a better and cheaper place to start. Sure, the dealers will usually point the finger at the chip and claim that it has caused the problem but, given their troubleshooting approach (it's like if you have an electrical problem and they replace the complete wiring loom only to find that the problem was the battery), I'm not so convinced that they know what they're talking about. YMMV

                          I'll keep you updated when I hear from the workshop.

                            Real bummer with the dealer trying to screw you, very disappointing I wouldn't have thought that they have any legal grounds.

                            I didn't keep my chip long once I realised the crazy pressures that it was putting into the system.

                            As for BP providing a 'warranty' on their fuel, not sure what is meant by that and good luck getting something out of them.

                              Keep me posted penguin, I have the Ch**it chip and have the same error code P000093 coming up, to me I though it was high fuel pressure sensor reading, and I was looking at the fuel pressure value near the oil filter. I have returned the chip for it's second time and they assure me it's fixed.

                              Once I removed the chip, the car drives fine with no fault codes, my mate also fitted a steinbauer and has had no problems so far.

                              Be interested on how you get on.
