Td5 Non Start Problems - Part 2 - Testing the Fuel Pump Electrics and Pressure output
Вставка
- Опубліковано 6 бер 2016
- Testing is better than random parts changing exercises but sometimes testing can raise more questions. Here we look at Testing the ECM output, relay operation, voltage drop and just for curiosity the amp draw from the fuel pump shown in wave form on a meter.
We also find that the pressure at the engine side of the fuel delivery not as we expect. - Авто та транспорт
Found these videos recently and I'm addicted to them. Not a landy owner (yet) but these videos ease the worry of maintenance and upkeep. Keep up the good work, I want more videos!! :)
+jakeybubbles One a week. Td5 one week then the Defender detail project the next. Still there is 420 videos in the video playlists.
I like your explanation about the hole system how it works clear talking taks mate
cheers.
Pleas do an FPR change vid, in your inimitable style and detail as I for one would find it useful. This vid is brilliant diagnostics lessons wit context and interpretation - live it :-)
+Danny Otter Okay cool. Will do shortly.
+Danny Otter Okay done. You can find it on the main channel page under Td 5
Hello Chris, many thanks for this, very helpful. Where would I go to get colour copies of the wiring diagram?
Hi I am testing no power from the ECU connector to the relay?
great video! TD5 fuel systems are a pain, worked on them a few times now and just don't like it haha, and personally i would change that high pressure pipe, a kink weakens the pipe and could cause a premature failure, especially with higher pressures
+Nick Heywood Yes that is a possibility. Kink has been there for some time as you can see by the dirt on it.
Excellent video thank you. Where can I buy a relay tester such as yours? When I Google I just get meter type testers that require the relay to be removed from the vehicle.
Where did you get your probes from, been trying to get a set like that but cannot find them anywhere, would appreciate any info that you have. cheers, James
my lr3 has this question too,Are u know how t fix it?
hey mate, do you know the pinouts for a 2000 D2 fuel pump connector ? ie: what is the hot wire to test for its voltage at crank?
Hi Chris ,what was that adapter you screwed into the fpr you was using with your burgen kit ? it was clearly not part of the kit and something from elsewhere.
My disco wouldn’t run, I changed the fuel pressure regulator and the pump . Still wouldn’t run . Eventually I studied the fuel system and found that little filter in the fuel line .took it out and hey presto, worked perfectly. That was about 8 years ago.never did replace it 😂
Wow ... that was a serious lesson and very interesting... Go on ... how much is that fancy Snap On multimeter ... can't say I'm not tempted!
+Matt Allen Nearly £1700 in the UK www1.snapon.com/diagnostics/us/VANTAGEUltra
+Land Rover Toolbox Videos Cool .... I'm erm ... just off for a quiet sit down in the corner where I may or may not be almost imperceptibly rocking myself...
well it hurt me for a while whilst I paid for it. It is only necessary if you are working professionally.
+Land Rover Toolbox Videos Or if like shiny things with wibbly wobbly all knowing lines on... :-P
ah yes there is that. You going to Buzzword your chassis?
Please please please do a diesel line return valve starting problem please I just can’t understand how to fix it I’m desperate please tell me how
Hi. I've got defender90 TD5 engine. I recently got it rewired. everything seems fine but when I start the engine, after about 15 seconds I get an engine light on the dash and the eccellearator doesn't work. do you know what might be causing this?
Warning light on the dashboard first thing is to look in the ECU with a scanner reader and see what it is telling you. Accelerator is a TPS which means Throttle Position Sensor. If the ECU can't read the position where it is at because there is no signal or poor signal it could be this flagging up a problem.
Do you know what the thread size is on the fuel temp sender? Trying to rig up a pressure tester and not sure what thread I need to cut!
+William Evans ah, you got me there. I did measure it on this video ua-cam.com/video/y221Lu8DD5M/v-deo.html but if you can't hear what i said it is 10mm x 1mm
Really good vid - thanks. Still trying to diagnose my problem. With mine the engine turns over but does not fire, fuel pump not powering up though there is power at the relay but not the feed signal, no glow plug light on dash.. relays checked.. fuel cutoff checked..loose connection checked, Immobiliser seems to work as expected.. car battery new and fully charged, Injector harness replaced in last 6 months and is clear.. No MIL. I even sent the ECU away for testing.. Not sure what to try next..
power feeds and the earth to the ECM? Have you checked them?
Trying to figure out which pins I need to check. The thing seems dead though.. Should say mine is the Defender td5
Tim Rogers how deed you solved your problem? I have the same issue on my defender td5 have power on relay. Fuse is fine but no power signal from ecu. If i connect relay its shows power on ecu signal but not starting fuel pump... Don't know what to do next
Yes I did! I was almost ant the point of despair. I found that as well as the main fuses next to the ECU, the ECU was powered by a small red 10A fuse in the main fuse panel in front of the gear stick. The fuse was fine but the fuse holder was covered on white oxidisation (the others were fine). I gave the holder a good clean and the put the fuse back in and the moment I turned the key I heard the pump power up, the glow-plug light came on and.. away she went. Have to say I found it almost by accident.. Good luck!
Tim Rogers do you have opportunitie to take picture of that fuse? And help me out with one cable?
Seem to be having an issue where my 2004 Disco 2 Td5 won't run when the tank goes below half. When doing a Pressure test I get about 5 Bar.(Took the temp switch out and measured it from there). Replaced the fuel regulator and all o-rings yet this did not solve the issue.
Take out your pump, dismantle and clean the 2 filter gauzes, 1 inside a fine one and 1 outside
Hi having trouble with 53 td5 disco she starts up then stops running..cuts out ..changed fuel pump , air filters fuel filter etc injection harness , it was oil saturated nothing in ecu stumped! Tia.
you changed the fuel pump but did you check the outlet pressure?
Td5 defender Start getting
Excelllent video., the big question is - are you interested in doing repairs - you can video it ! Thnx
Not a big question and no, I am too busy at the moment helping to maintain a large fleet of commercial vehicles.

But such a skill you have - and a proper mechanic/technician. - not just ‘a fitter’. Any recommendations in the Nottingham/Derby area.? BTW - love Kings Lynn and Tuesday Market Place
Hi, fine relaistester at 1:48. Where can I get that? Thanks!
ebay
@@trailerfitter2 only found it in USA. Have you an item no./description in UK? Thanks
what voltage does the battery drop too whilst you crank?
td5's dont really like to start with less then 11.3v whilst cranking!
and 11.6v on an auto!
+The CluckAnator Ah I will find out for you, Easy to show the voltage and current draw at the same time on my meter.
+Land Rover Toolbox Videos
When you fitted the new ecu, did you code the injectors to the ecu?
Certainly did.
+Land Rover Toolbox Videos
how long do you crank it for?
when i change stuff in mine, even running the 'auto bleed' for about 10mins, it sometimes does still take 10-15mins of cranking (30 second cranks) even to fire up!
even on a genuine new land rover pump!
Have you removed the pump yet?
i was only getting 1.5bar on mine due to the gauze on the bottom of the pump, it self!
Yes pulled the pump out and it is clean
Have you done a Freelander 1 sunroof repair?
+Paul Scott nope I exchanged the freelander we had for a Defender pile of bits
plese help td5 eingine ingector chang for no ingine start what problem
not enough diesel. It takes an effort to start after the head has been drained of diesel.
Where can i get this pressure gauge?
Ebay
I have that Bergan kit... it's pants. Got a suggestion for a better one?
+Adrian Kingsley-Hughes Not yet. I will need to shop around.
+Adrian Kingsley-Hughes Sykes Pickevant have a low pressure fuel pump test kit which is far superior to this but very costly. The Bergen kit appears to be a copy of that.
Hi.How to communicate with you
try one of these you can make your own lines up . www.autoinform.co.uk/shop/#!/Frank-Masseys-ADS-Custom-1-TO-10-BAR-GAUGE/p/4399440/category=961005
+MrBLANNY1 yes i have seen that and it is dampened which makes it possible to read with some pumps.
