@@LMAutoRepairs hello sir, i have one astra g 1.6 16v and his crank but no start and when crank engine ligjt blinding, i slow in down with 2 nd gear for start engine sometimes i out dhe crankshaft sensor cable car starting and put cable when car is start what to check or change sir
Well, funnily enough..my fault code is P1600 replace ECU..but sometimes the vehicle wont crank but then does..I thought there maybe a connection with what you diagnosed on your vehicle..I cant seem to find schematics on the starting circuit!.. Anyway..my issue...many thanks for your returned messages..take care.
Mate, you are a star, I sent my ECU for repair as it had the same fault as this, they sent it back saying my ECU was ok, I started searching youtube and came across you, and you were 100% right a broken wire in the harness 10-minute fix, so wanted to say a massive thank you to you sir
Wow my zafira has been off the road for 3 weeks now been looking all over the internet for help come across this video last night followed your steps and i had the same problem as you all fixed now can't believe it was just a small piece of wire.thank you
Here comes a big thank you from Germany. I had the exact same problem on my Zafira and thanks to your video I was able to get the car running again with just a bit of soldering. Wish you all the best !!!
I can't thank you enough for this video. My wife's astra had exactly the same issue. I found the wiring corroded and broken along the same loom but further along towards the battery. Thank you so very much. Kind regards Melvin Jarvis
Thank you sir for your support. I had exactly the same failure codes and the same failure mode. After fixing the brown-yellow cable, the engine is running fine 😅.
Nice video mate ! I did not have the same issue but i used your diagram for the Simtec MS 75 ECU system (Opel uses more systems). Low voltage to engine ECU - Replace ECU code - Brake lights on all the time. Checked all the powers and had a wire with 2.8 V on it. Corrosion in de taped part next to the connector. Fixed the wire and it runs again. I post this for a future reader with the fault. The break lights go on by the ecu, i think it runs on can low, did not see anything in the can signal. Cheers people !
I did notice before you by passed the Main Relay you didn't have a tach signal but once you did you could see about 150rpm when cracking, but didn't initially start. Pain to find the main fault when you have to find 3 or 4 other ones first! Good video once again!
Had the exact same issue 4 weeks ago, cost £300+ to have it sorted by a specialist. One thing we also noticed was this fault also caused the brake lights to stay on when in ignition but turn off when we pressed the brakes
good job thanks for share but there is something not make sense , you are bypassed all relay but car do not start is it the ECU disabling its injectors when it not sensed the control wire of main relay not feeding ?
Hello, where did you get your wiring schematics from, i have a 2004 1.8lt Holden astra h with no spark and the fuel pump is not turning on with the key
That spindly wire you found external to the loom was much thinner than the manufacturer’s original. Someone fitted that bodge wire to overcome a previous fault, to overcome a poor connection or failure of the original wire. The bodge wire then failed itself ! bringing back the original fault......
That external wire seems to be solid conductor prone to fracture and break again, its not a stranded wire, seems like someone took a telephone line wire to bypass the original faulty wire.
These Vauxhalls really are a mess under the bonnet. Lots of corrosion everywhere. Definitely cars toavoid. Well done in finding the fault. Excellent work.
Another fantastic video and fantastic job :) Hardest part of our job is to find a problem after someone was there before - I'm pretty sure, that wire wasn't fitted by factory but you've found it
Nice job Leo, but why the car didn't start when you bypass the main relay and start only after fixing the control wire of the same relay I don't get it?
I can only guess that that wire was feeding more than just the relay... Thank you for watching and for your comment plus, the wires touching... they might were causing other issues... Thank you for watching and for your comment!
Thank you for this video. what are the names of the tools you used for bypass main relay? and which pins do you choose when you need to do a bypass (are they pins 30 and 87?)
Very nice Luis, thanks for sharing ... btw ... long time ago you had said "i could do a checksum file repair video if my foĺlowers want", hehehe ... i was searching one and couldn't find any. Anyway, i know you are very busy person :) thanks for sharing, and wish you the best :)
Sorry to bother you. But is there any chance you can fix my fuel pump relay low voltage problem on my Astra mk4 it's been three years and no mechanic I take it to can fix it. Cheers.
Ok now I understand that. But from where you know that 49 or 62 are connected to this relay. I got near same problem, but for me the 49 work but the 62 dont work. And if i take ignition without try to start the engine, all brakelights are lighting. Still searching my problem😅

Where abouts are you based?

@@LMAutoRepairs Can I ask a question? You look like a guy good guy. I have an Opel Astra F, from 1996. I keep it in good condition, and I heard noise from the clutch, and transmission. I went to a mechanic, to change the clutch set, and probably the whole transmission, cause its cheaper that way for me. After the oil change and the transmission swap, I have low oil pressure, it lights up, and I can even hear sometimes the engine is dry. Wtf? Is this just a coincidence, that the oil pump just went out right after the fix, or did they fuck up something? Before that, engine was perfect. Sry for long post.

Great systematic testing..I like your technique of testing..would you know by chance if the starter circuit is combined with this circuit?.. I cannot find any reliable info that I can test in full confidence..Many thanks
Wouldnt it have been faster to check the main relay control wire by putting test light to power and removing relay and checking at control wire pin to see if computer lights test light proving that it is controlling relay rather than unplug computer and finding wire with continuity check?

Im having such a weird issue with my 2007 astra 1.6 sxi. It cranks but wont start 1st try , 2nd try it fires right up. I had code for camshat sensor so i replaced it and it was great for about a week then started doing it again. So i swapped out the NEW top camshaft senor with my old 1 and once again , it started 1st time everytime for about a week and then went back to cranking but no start on 1st turn of the key. It is obvioulsy intermittent but changing out the top camshaft sensor seems to fix it for week or so ???? Im stumped lol....
Hi. same problem on astra 2008 not starting but engine turning over, also the rear brake lights are always on when ignition is on. I;ve not yet checked the wiring but does it sound like the same problem? Was the broken wire broken within the loom or the multi pin connector?
Hi You must have skipped parts of the video, I showed exactly where the issue was in this case... Does not mean your issue it is the same... Go through the appropriated checks, etc... Thank you for watching! 👍👍👍
@@LMAutoRepairs Many thanks for the quick response. I've checked for the same broken wire problem and there is no loose wire in the multipin connector housing or any sign of soldering on to a wire. Shame as I was pinning hopes on that easy fix you had discovered.
Hi @Lmautorepairs Wondering if you can possibly help in guiding me with your knowledge. I have a 2009 Astra H 1.8 petrol which has a cold starting issue. It struggles to start and will cut off first few goes but once it starts and warms up the starting issue goes away untill the next cold start. Also smells of petrol and mpg is very very bad. Exhaust lets out excess amount of fluids/steam? No fault codes, has had new plugs and new coil pack. Evap is doing what it needs to. On live data short fuel trim is between -9 to +5 and also showing as running lean. Any help will be greatly appreciated!
Hi If is running lean check for air leaks... or blocked injectors... but if you say is running on once warmed, I would be more inclined for an air leak somewhere... 👍👍👍
@@LMAutoRepairs I’m wondering if you are local to me and if so are able to have to look into it for me obviously if you have the time. I’m in London. Sorry I’m not sure where to private message you from. Thank you!
Cheers from Mexico. I have a No Crank case with an Astra H 2007. When I open the ignition switch I hear the fuel pump working. The starter motor is good and there is continuity between the relay and the starter. I followed your diagnosis porcedure to check continuity between the main relay and ECU, and it has continuity. Do you have any idea?
@@LMAutoRepairs Hi my friend. I finally managed to get my Opcom Scanner working. When I try to read Engine fault codes I get comunication error with ECU. But if I read code for ECU and CIM module especifically, I get the following: ## ECU P0115 - Engine Coolant Temperature Signal Range/Performance (71) - Present P0460 - Fuel Level Sensor Circuit Range/Performance (71) - Present P0500 - Wheel Speed Sensor Circuit Range/Performance (71) - Present P0654 - Engine Speed Signal Range/Performance (71) - Present P0705 - Automatic Transmission Gear Signal Range/Performance (71) - Not present P0550 - Mileage Circuit Range/Performance (71) - Present ### CIM module B2961 - Switch Position Ignition Key Circuit Malfunction (08) - Not present U2105 - CAN-Bus No Communication with ECM (Engine Control Module) (00) - Present U2106 - CAN-Bus No Communication with TCM (Transmission Control Module) (00) - Not present U2111 - CAN-Bus No Communication with EPS (Electrical Power Steering) (00) - Not present U2120 - CAN-Bus No Communication with AHL (Headlamp Levelling Device) (00) - Present Any ideas will be appreciated.

Hi, I have 2009 Astra h z18xer it has code p0685. Crank but no start and cant hear the fuel pump prime when turning ignition on. I think I have same problem, are you mobile mechanic? Thanks
Hi guys. I know this is an old thread but still trying my luck for a response. I had my starter motor serviced on my 06 Astra H cdti. But when I install it back on the car it starts winding before I turn the car to start (key on On motor is kicking in) wondering what could be the cause.
@@LMAutoRepairs The issue was the brushes, had them replaced. Starter seems to work just fine when I bench test it. Dont think it's the alternator because that was not a problem before. Could be a bad connection like you suggested. Or could it be the starter relay?
Do you know what the problem is, I have an Astra H 1.6 16v XEP twinport, it reports a cylinder misfire error when the weather is cold, the bomb and spark plugs have been replaced but the problem still exists?
Hoping someone may see this post and respond. I have an Astra Twintop 1.8l. I was going to switch batteries but did not want to lose the programming information...so I loosened the two main bolts of the battery terminals so I could start the car then switch batteries whilst the engine is running. With the battery terminals loosened I tried to start the car. As I turned the ignition, I heard the starter stuttering because of the loose battery terminals and suddenly the entire vehicle shut down. The battery has power but there is no ignition lights or anything. The Vehicle is completely shut down. What do I do? I cannot even close the electric windows. What has happened?
Hope you have leaned the lesson... The only programming information you would loose, would be the clock and date, possible the radio stations and the windows limits... all easy to resolve, and does not really worth the risk... Anyway, check fuses... if that is all good, there is a possibility that the low or spike voltages have damaged some module... Hope you get it sorted... 👍👍👍
Great diagnostic skills, however I’m confused why did the car not start initially when you bypassed the main relay ?
Most likely that broken wire was feeding something else required for the engine to start...

Hi
Have you had the car scanned, live data checked etc?
👍👍👍
Hi my Vauxhall’s Astra 2011 mk6 one morning it starts next morning it won’t start any suggestions?
Scan the car, and go from there...
Thank you for watching!
Excuse me, sorry for the late follow, but what is it you sprayed on the battery terminals before and after connection.
Similar to this...

Im having such a weird issue with my 2007 astra 1.6 sxi.
It cranks but wont start 1st try , 2nd try it fires right up.
I had code for camshat sensor so i replaced it and it was great for about a week then started doing it again.
So i swapped out the NEW top camshaft senor with my old 1 and once again , it started 1st time everytime for about a week and then went back to cranking but no start on 1st turn of the key.
It is obvioulsy intermittent but changing out the top camshaft sensor seems to fix it for week or so ????
Im stumped lol....
Have you scanned the car?
Do you have a scope?
That would be the best way to approach that...
👍👍👍

Was scanned and only code was for camshaft senor . I dont have a scope but my mechanic should so will start there next 👍👍
Hi. same problem on astra 2008 not starting but engine turning over, also the rear brake lights are always on when ignition is on. I;ve not yet checked the wiring but does it sound like the same problem? Was the broken wire broken within the loom or the multi pin connector?
Hi
You must have skipped parts of the video, I showed exactly where the issue was in this case...
Does not mean your issue it is the same...
Go through the appropriated checks, etc...
Thank you for watching!
👍👍👍
@@LMAutoRepairs Many thanks for the quick response. I've checked for the same broken wire problem and there is no loose wire in the multipin connector housing or any sign of soldering on to a wire. Shame as I was pinning hopes on that easy fix you had discovered.
Have you scanned the car and looked at live data?
That might be helpful...
Brilliant work - love it!
☺️
Thanks!
👍👍👍
What setting do you have your multi meter on
Continuity/ohms reading...
👍👍👍
Very clever, nice work.

Thanks!
My 2009 diesel 1.7, was going to 4000 rpm when pressing the brake, wont start, was trying to start when driving and smoke from the start engine
Main ecu fail
Hi @Lmautorepairs
Wondering if you can possibly help in guiding me with your knowledge.
I have a 2009 Astra H 1.8 petrol which has a cold starting issue. It struggles to start and will cut off first few goes but once it starts and warms up the starting issue goes away untill the next cold start. Also smells of petrol and mpg is very very bad. Exhaust lets out excess amount of fluids/steam? No fault codes, has had new plugs and new coil pack. Evap is doing what it needs to. On live data short fuel trim is between -9 to +5 and also showing as running lean.
Any help will be greatly appreciated!
Hi
If is running lean check for air leaks... or blocked injectors... but if you say is running on once warmed, I would be more inclined for an air leak somewhere...
👍👍👍
@@LMAutoRepairs thank you very much for taking the time to reply and for your guidance. I will write back once I’ve had a look.
@@LMAutoRepairs I’m wondering if you are local to me and if so are able to have to look into it for me obviously if you have the time. I’m in London. Sorry I’m not sure where to private message you from.
Thank you!
Hi
I am quite far from London, but I do this as a part-time anyway... sorry if I can't help this time...
👍👍👍
Great video, I have a similar problem to this, but my astra 1.9 3dr starts with easy start.... Just wondering do you do private work? Thanks
Did you every fix this mate I have the same issueb
Cheers from Mexico. I have a No Crank case with an Astra H 2007. When I open the ignition switch I hear the fuel pump working. The starter motor is good and there is continuity between the relay and the starter. I followed your diagnosis porcedure to check continuity between the main relay and ECU, and it has continuity. Do you have any idea?
Do you have any codes on the ecu?
Thank you for watching!
@@LMAutoRepairs Hi my friend. I finally managed to get my Opcom Scanner working. When I try to read Engine fault codes I get comunication error with ECU. But if I read code for ECU and CIM module especifically, I get the following:

It looks like you have a choice, no fuel or no battery :)
And many times both...🤣🤣🤣
👍👍👍
Excellent video.
Thanks!

Good repair, thank you
Thanks!

@@LMAutoRepairs Please sir, can I have your phone number?
How do you charge for this
Another great video Luis can I be a pain and ask where you get your wiring diagrams. Cheers 🍻
Multiple places...
One of them is HGS...
Thank you for watching and for your comment!
How do I hire you to fix my car
Hi, I have 2009 Astra h z18xer it has code p0685.
Crank but no start and cant hear the fuel pump prime when turning ignition on.
I think I have same problem, are you mobile mechanic? Thanks
Hi
No, I am not a mechanic...
Start by checking the basics... fuses, relays etc...
Thank you for watching!
Good job mate👏
Thanks!
👍👍👍
Hi guys. I know this is an old thread but still trying my luck for a response. I had my starter motor serviced on my 06 Astra H cdti. But when I install it back on the car it starts winding before I turn the car to start (key on On motor is kicking in) wondering what could be the cause.
Either a faulty alternator, or you have connected it wrong...
What was the issue before, for you to have it serviced?
👍👍👍
@@LMAutoRepairs The issue was the brushes, had them replaced. Starter seems to work just fine when I bench test it. Dont think it's the alternator because that was not a problem before. Could be a bad connection like you suggested. Or could it be the starter relay?
Could be a sticking relay... unplug it at see what happens...
Nice diag good video keep it up
Thanks!
👍👍👍
Do you know what the problem is, I have an Astra H 1.6 16v XEP twinport, it reports a cylinder misfire error when the weather is cold, the bomb and spark plugs have been replaced but the problem still exists?
Injectors perhaps?
Have you checked compression?
Thank you for watching!
@@LMAutoRepairsI didn't check the compression, but I doubt the valves are wrong, because weird detonations are heard on the exhaust!
Excellent troubleshooting skills!. Regarding that corroded pins, is it possible to replace them individually ?
Cumprimentos de Portugal :)
Yes it is possible to replace them individually...
But you need some dedicated tools to push the pin out...
Thank you for watching!
Obrigado!
Hoping someone may see this post and respond. I have an Astra Twintop 1.8l. I was going to switch batteries but did not want to lose the programming information...so I loosened the two main bolts of the battery terminals so I could start the car then switch batteries whilst the engine is running. With the battery terminals loosened I tried to start the car. As I turned the ignition, I heard the starter stuttering because of the loose battery terminals and suddenly the entire vehicle shut down. The battery has power but there is no ignition lights or anything. The Vehicle is completely shut down. What do I do? I cannot even close the electric windows. What has happened?
Hope you have leaned the lesson...
The only programming information you would loose, would be the clock and date, possible the radio stations and the windows limits... all easy to resolve, and does not really worth the risk...
Anyway, check fuses... if that is all good, there is a possibility that the low or spike voltages have damaged some module...
Hope you get it sorted...
👍👍👍
Nice job! What is the tool at 3:23 called and what's it for?
Is a cleaning toll... found it on eBay...
