    4.2 D4D - hot start issue!

    this all makes total sense! It sounds laboured both when cold and especially when hot! This may sound stupid but imagine a classic car with external cranking arm... it feels as though it just needs a stronger arm to spin it if that makes sense? Lol Massive help thank you everyone! 😀

    4.2 D4D - hot start issue!

    people have suggested the starter but wanted to check! makes sense with clutch dust etc did not even think of that!

    4.2 D4D - hot start issue!

    was it just when hot? mine cranks and starts thudding sounds like its a timing issue but if was timing it would run like 🤬🤬🤬🤬

    4.2 D4D - hot start issue!

    XTR Diesel has done 149k miles and starts fine when cold but after driving for a few miles and engine is up to temp it will not restart, it will just crank and crank... Wait two mins to let engine cool down and it fires up fine? Tested resistance on temp sensor and it is within spec so I am at a loss!! Any suggestions would be greatly appreciated.... it is becoming dangerous now and mechanics say they cannot find anything!!

    4.2 D4d Scv Valve Replacement

    amazing!! have ordered some bits off eBay and will give it a go the weekend... whilst doing the pads and discs!! great help!
  6. so many people have this issue and it appears to be from many years ago as well.... Mine does the same and all above components replaced/cleaned... mine only does it when cold now but I have tracked it back to the vacuum switching valve (red one below the map) it's putting out 43 ohms across the terminals but does get blocked so I periodically spray wd40 through it.... whether this is just coincidence I do not know??? EDIT: Random conversation with a bloke at work said his 08 plate mazda had the same issue and they had to change the ECU.... fixed it for good!

    4.2 D4d Scv Valve Replacement

    dont suppose you know which side is best to fit one to? pump side or tank side of the fuel filter?

    4.2 D4d Scv Valve Replacement

    is there a way to change the non return valve in the filter head or is it a case of replacing the whole part?

    4.2 D4d Scv Valve Replacement

    had a quick look but no immediate evidence, my suspicion has always been fuel pressure but it only does it when it has been driven for a while and gets hot? cold starts are fine....

    4.2 D4d Scv Valve Replacement

    I did replace the fuel filter in the summer and replaced with a Bosch! I even replaced the in tank element.... What I am getting which may be nothing, is the plunger on the filter housing never remains stiff? I go to periodically push it and I always get a squelch or two then it stiffens up? Regarding the sensor I spray its the one under the yellow circle!!

    4.2 D4d Scv Valve Replacement

    I am getting the jerking around 2-3k but with no codes and all resistance and voltage for all sensors etc is within spec.... the only thing that does work is filling the brown/red vacuum valve (unsure of name or part number) with wd40 as it appears to get clogged!? I read it somewhere else and its a different car when I do it... again voltage on the points and resistance all within spec! I also get the hot starting issue but think a new upgraded 2.2kw starter may solve this?? SCV where changed about two months ago but above issues were not resolved! Only reason I took the plunge and spent the cash was a Toyota dealer dyno threw up no codes and the garage even said "um we dont know??"

    4.2 D4d Scv Valve Replacement

    Evening all.... I know this is an old thread but I tested my scv valves and on 2.2 ohms on both so is this indication they are faulty? Car had been off all day so the engine was stone cold.... outside temperature was about 18 degrees?

    Turbo Recon.

    I know this is an old thread but I have been having the same issues. Investigation has let me to the VSV (turbo boost pressure vacuum sensor valve) the one at the back nearest the turbo.... my question is... should this buzz when the ignition is on but engine not running??

    intermitant lack of power/flat spot

    I bought mine from ebay £150 ish for OEM from Japan. Test them with a multi meter first as this is everyone go to issue, I had mine checked as I know the garage who did it and luckily they had not thrown them out.... they worked fine after everyone told me that was the problem so £150 wasted.

    intermitant lack of power/flat spot

    to add to this the bad starting is apparently a known fault on the RAVS MK2 D4D, the starter is a 1.4kw which as they get old just lose enough power to make it harder to start, its worse in the summer months when the car needs a bit more of a push and when the engine is hot, it will just crank and crank.... answer is a modified 2.2kw starter, you can buy them for around £89 and is an easy change with a Haynes manual. Failing that a local indy can do it in under an hour!
