Yasterday I had a problem starting my td4, it started after a few tries. Today it would not start at all. I have had no previous problems(engine wise) I spoke to a relation who suggested a few things to try i.e make sure I was getting fuel to the injectors. He also suggested checking the glow plugs. I might sound thick but but where are the injectors on a TD4 are there any? He suggested it may be a direct injection and not have glow plugs.
Can somebody set me straight? Also any suggestions why my car won't start? I'm just about up to selling the piece of crap!
 
check ta see if the fuel filter has bin changed this is ya first hit,and yes it has got glow plugs and is a common rail fuel injection, after that check out search as most the common faults are listed,best oh luck. . .:) :) :)
 
ta ming! It is getting fuel but I couldn't locate the glow plugs can you tell me where abouts they are? Is it easy enough to check them?
 
I have had the car for 6 months and never noticed the heater coil light thing on the dash come on I know there is one there because it flashed on once a few weeks ago. It litterally stayed on for less than a second. I take it this could be the problem what are the possibilities? How can I remedy it?
 
Its a quick fire system not like the old days when ya had ta wait for em, if youve got one gone it will still start ok ,maybe struggle in winter, check fuses , they are located under cowling glow plugs that is, , ,:)
 
Checked a few posts and the glow plug thing sounds normal. Should I now be looking towards the injectors for the rason of not starting?
 
Drarrn ,scuse me but think yer going too deep, fuel filter is first ,and maybe heaters,then its fuel pumps 1&2 then high pressure fuel pumps [rare] then look at injector's [very rare],think you've jumped the BASICs, the other thing is have you had ****e fuel in the system[very common] also the pre heat relys on sensors for ambient temperature[could be one of them] always look for the simple first ,I'm only tryin ta help. . .best oh luck. . .
 
I have changed the fuel filter,still no joy! I have fuel leading up to the injectors but I don't seem to be getting any siganl to the injectors. Does anybody have any idea if there areany fuses/relays that I should be checking?
Failing that any other ideas? I am up to the point of seriously thinking of getting rid!
 
I got a mate to come around and give me a tow to bump start the TD4 first try it kicked up drove around for a while it was running perfectly turned it off wouldn't start again. What does the Immobiliser immobilise? Could this be my problem,has anybody had anything similar? Any ideas how to check it?

well i dont know if this will help ,but first how do ya know you have fuel to the injectors? and i take it youve checked the glow plugs[1] for resistance they should all be a bout the same and no open circuit[2] volts on common wire via earth, nb if yer earth on your engine is poor , it will not work, if you have all these and it still wont start ,yer lookin at injector signals [not injectors] or imobiliser circuit, but afore we go into deep thinkin, go back to basics first , if yer high pressure pump is shot then nothing will work, also ya got 2x low pressure pumps one in yer rear bit[snort]and one in rhs engine bay,the one in the rear is a known weak link, you can check this by dissconectin at fuel filter, it should **** out clear wif no foam,foam means its shot,best oh luck. . .
 
Just read ya other bit bout the tow and startin ,so that does away with injector signal/imobeliser, so try my rear pump thought as you might get some fuel but not enough,also put ya hand on the rhs in engine pump get ya mate to turn ing on[dont start it] and should feel that pump run for bout 12sec then go off[pump pressure time out]and it could still be ya plugs,. . . .
 
Pump ok! Somebody said the engine should still start without the glow plugs as the weather has been hot today and the engine was run for at least 15 mins imediately after switching off trying to start again!
 
Thanks Mondo! Another person has suggested the camshaft sensor(that is the one on top of the engine near to the maf isn't it?) Do you have any ideas how to test it? Been on to the dealer £55 so before I throw any more money away I'd like to be as sure as I possibly can be.
 
At last a bit of light at the end of the tunnel! Had the AA out and he is near certain it is the fuel pressure regulator. How can I be certain, what ways can this be tested?

He put some easy start in the airbox and it kicked up!
 
Just to see if anyone else has any ideas besides matches and petrol.

I have had my car (TD4) to an independant landrover specialist, who has had the car on the computer diagnostics. Everything is looking as it should be with the car fuel pressures, immobiliser has been reset, ECU cleared and reloaded glow plugs checked, injectors are fine and the camshaft sensor has had a new one on just to check.

The car still turns over will not start, will start with easy start or a bump!

The guy I took the car to has his head in his hands, he has been fixing Landrovers for 30 years or so, he is plugging it in to a machine worth twelve grand and has never seen anything like it before.

I know that I'm clutching at straws but does anybody have any suggestions however stupid they may be!:(
 
That will be the stupid rear pump gone weak[there is not an easey way ta prove this one out] the other pump is called a lift pump[cos the tank is lower than your high pressure pump] and the only answer i can give is ,when it starts wiv a tow,your swilling the diesel in the tank enabling the fuel in the pump to push just a tad more,hard call this as ya might go through all this hassle and follow my lead and find it was a waste er time, but i can take it,can you,best oh luck. . .:)
 
Hi Ming

Just had the "landrover specialist" on the phone he seems to think the problem is the high pressure pump! And quoting £500-£600 to fix. However he is not definate! I mentioned about the lift pump and he doesn't think it would make much of a difference! Correct me if I am wrong but I assume that the high pressure pump is mechanical? If this was faulty presumably the engine would struggle once it is running? Would a gravity feed in place of the lift pump provide enough pressure to start the car if that is the problem?
