Great video

I got the same problem, no check engine light, but no ignition light and engine can start. BUt I cant communicate with ECU anymore...so it seems to be working, but not communicating?

Did the vacuum pump cure the issue on this car as I have the exact same symptoms with a car I have in Spain and I’m working with a limited tool kit and no miti vac but it does have positive pressure from the solinoid supply and negative from the brakes

Iv had the same exact issue today aswell mate thank you for that video upload .

So what would be the solution for this fault? I have exactly the same issue, and hoping not to be ripped off by those that, as you say, pull out the parts catalogue and go crazy

just did the same with my car, similar problem, only thing lighting up is the grey square box, i guess a relay? bottom right of your video here, but its situated bottom left of CJB, what is it? should it be hot?

Mine is focus 2013 se version, 5 speed manual one, cruise control works on 3rd gear, but not on 4th and 5th, I’m thinking of something to do with programming, issue started since I sent the car to the body shop

where about are you based fella? got a poorly jaguar XF parasitic battery drain, im Kidderminster, near Birmingham

Thanks!!

Good video

Can you plz help I have the same problem with my s max 2.2 except I put a new turbo on and did a eco map now it will only start if I probe the relay and help would be great Rhanks

I think you may have solved my problem. My Galaxy wouldn't crank, but when I let it roll a bit it started. I assume therefore that it must be a dodgy starter motor, as did the garage. When I went to pick it up, it wouldn't start. The mechanic told me to press both the clutch and the brake. It started, but I told him I had never had to do this before and only needed to depress the clutch as normal. Having come across your video, I checked the drivers foot well and found it to be very wet. I will take it back to the garage and get them to investigate the corroded wire. I'm sure that is the problem. Cheers.

Good diag

Yeah hi mate your videos very interesting I've just brought 2.2 and it's doing like the same but 1 minute it will start and then when I to turn it over I get nothing but when I get a jump start it will start straight away so I don't know if you know about that or if it could be the relay thank you

Hi, I have a Ford Galaxy 2017 auto keyless stop/start system. Before the car started and ran ok, I did an oil,air, and fuel filler service when I about to start the car ,I had ignition, but know crank, brake peddle press and the green light is showing and the start button, when you press it, it flashes and don't start, check all fuses all ok , check starter relay ok , feed 12v to the starter ok, I even check. BCM that ok, now I'm stuck can some help me please

Good to see you back very good diagnostic and more videos 🙏

You deserve a lot more views. Your a really good diagnostic technician

Im trading mine in. Mechanic cant find anything wrong. One day it works great, others days trouble starting, next day cuts off while driving.

Interssting video ,but why not just read the amps draw on the clamp meter display you should be able to see 55 amps on that?

There is a small oil filter in the head. You can google how to change it. If it is plugged with sludge the oil flow is limited. Change it periodically (and keep the oil clean) and you wont have this problem.

I have a vauxhall vivaro with a constant red immobiliser light, i've tried everything and i can't sort it... was working one day and then not the following day

.. do you know part nr ?

Thanks this help sort my master out .

Long way around on a fiat just go from the negative on the battery to a metal on the engine with jumper cable

Thank you for this

You legend! This was the problem exactly and due to a water spillage a few weeks previously. Thank you!!! For reference for others. The weird thing about the problem I was having is that it would start but needed to have both brake and clutch depressed and 2 pushes of the start button. Now all back to normal. Thank you!!!

Non start stop master cylinder fitted???

Do you cover denton mancher

Hopefully you are still monitoring the comments.... I've got 95% of the same conditions featured here, right down to the previous Aircon leak. The 5% difference is that when I trigger the start button... The dash shows "press clutch to start" and that dismisses when I press the clutch (But no response from the engine) Does that mean my clutch wire is likely ok or does that switch feed different modules and there could still be a break? Appreciate your thoughts before I get to ripping it out!

brilliant video good to hear you pls send me a link to reg for waring daigram pls feed me back thanks a lot

Hi, very good info. I've a 2008 Renault Master wondering where you got the details wiring diagram from as struggling to find one online.

Brilliant best and simple explanation video seen in a while. Do more pal

THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi, I have question. Mine does not start because the bottom contact which is ne relay in the fuse box do not have a ground, it is missing. Where should I look for to find grounding.

Seen most of your videos, got a good one for you…. My Inlaw has jag xf battery drains, BUT also powers goes on and off on its own??? Any ideas… Sent from my iPhone

Excellent video, well done. I'm having a problem on the same vehicle Clio 1.2 16V with a pin number 20, it's for AC control to rise the RPM's when AC is turned on, but there is no voltage. The AC works perfectly with direct 12V. I like to put direct currency on pin 20 but i do not now exactly voltage for this pin od the ECU. Does it 12v ? Pls a need help to check and resolve this issue

Brilliant video nice to see proper diagnostic, step by step, and keep them coming

Sloppy clutch job… Didn’t bother cleaning anything by the looks of it.

Please help, mine does that, but.... After couple time of pressing the start button, it finally starting the car. And this accurs not every start of the car. May it be just. Relay.?
