2008 Honda Civic 1 8 Crank No Start. Starts with scanner connected?? 

So happy people like you are on RU-vid. Did a rebuild on my 07 Civic 1.8 and had the same issue, bolted the unit as shown back to the block and the problem was solved! Thanks for taking the time to post this and share it with the home mechanics out here!

Thank you. It was the problem, my father had replaced m head gasket and he watched your video to find out which bolt he had missed. Thank you so very much it saved a lot of time and money.

You’re my hero, I just put a head in my daughter’s car and it started but after driving it quit. It had the exact same issue that you showed. The one bolt I missed. Thanks!!!

Recently put a clutch in mine its same model went to start it up after finishing and this same exact thing happened. The gauges were kinda dim and cel was on also so decided to plug a cheap temu obd2 reader i have in to see if it says anything and noticed all the gauges lit up and cel went away so I tried to start it and boom started no problem but soon as unplug got the same thing. I've been driving around for 2 weeks with this plugged in. Glad I stumbled on this video I couldn't find anything when was actually looking for it, crazy how google works have to use the right words when looking. I will definitely be trying this tomorrow. Thanks for sharing your knowledge with us less mechanically inclined!

Bro your a genius! Thank you so much. Ive been going crazy for 2 months trying to find the problem. They changed my engine and forgot to put that bolt in also. It would only start with the obd pluugged in. You deserve a medal

Dude thank you so much for this video !! I did a transmission on mine and undid this exact same bolt, I put everything back but missed this one. I looked for hours trying to find the missing ground & even ended up replacing the fuel pump 🤦.

Thank you, thank you, thank you!!! I redid my clutch on my Civic and put everything back together. I even remembered to put this bolt back in the wire harness, but because it was so badly corroded It was not making the proper ground connection. So I took a small wire brush on a drill and clean the bolt and the eye and double checked and wire brushed all my ground wires all the way back to the battery and the wire through the transmission and lo and behold it started right up. So for anybody who has done their clutch and wonders why their car won't start back up after putting it back together this is the solution I searched the internet for 5 hours seeing if anybody had the same problem and this is the only video that I found that has helped me.

Bro thank you so much I’ve been losing my mind with my civic bless the fact you made this video I love you

January 30, 2024, Thanks for this video I got my friends car started, Your amazing ✔️

You are a life saver man hands down the best mechanic in who post videos and shows in detail what people are looking for. Thank you man. I hope you see this an Basket in it man because you deserve it.

In my Denzel Washington voice from Training Day, "My #!$$@." Thanks for real. Its pouring down raining and I couldnt get this civic started without my scanner after the engine swap. You are a Saint for posting this video.

Thanks man. I went through every single procedure trying to find this missing ground. With no power to my fuel pump I went through every fuse relay ground ignition ect trying to find the cause. I was thinking maybe the ecu fried somehow. Found this video and it was my problem. Can’t thank you enough I had no idea those were grounded.

THANK YOU SO MUCH .... FINALLY WORKED !!!

I had same issue when rebuilding transmission... thanx for the video many shops couldn’t find this problem

Great info same exact thing happened to me with replacement engine except it had a dongle in obd connector so we didn't know til we put scanner on to see if monitors were set for emissions.

tnx for video,,have beena doing auto electrical since 1984,,,i got a civic like this and i was like shocked to see this,,,lol,,,,

I had my 06 civic thermostat replace and they forgot to put the screw back in thank you for your info.

Thank you so much sir I had this for days now but thanks to you its working now

Thanks for the video. Just helped me with a similar situation..

Thank you thank you fixed my my car 🙏🏼🔥

Pin 16 sir 😉. Power at pin 16 , can data line at pin 6 and 14. Chassis and sensor grounds at 4 and 5. Nice fix , and great place for a ground that doesn't look like a ground.

Thanks for this, I have the same problem , and I have been around that area so will go and have a look if there is a missing bolt :-)

Great video men

My Civic was a defective fuel pump, it would start and then dies, then rest the key the fuel gauge was reading empty to half tank. Dealer wanted to diagnose the car for $450. I simply replace fuel pump with new one from warrenty, and the car now runs.

Very nice thanks

Thank you much appreciated 🎉❤🎉🎉 worked for me

Can you use still use the car for while with the paper clip ?

Thanks. I love you so much

Same to me . Thank you

Thanks your nice video sir!

Just bought a used 2010 with the same problem!

Great video,very helpful,thanks

Thank you my car same problem

Is it just a bolt or do you have to run a wire to it too

Thanks for your help

for the Honda Civic FD3 hybrid, is the ground located there the same?

If I ever see you, I owe you lunch!!

Had those cases a couple of times. As it turns out it was ground issues.

Size of the bolt?? Thank you for this video.

This is ridiculous, I thought I screwed something in the engine, same thing happened to me,rebuild an engine put it in doesn't start, put the obd scanner, starts right up,so yeah I didn't bolt that hornest assembly also

Great thankyou.......

I know exactly where you guys are on Hercules I used to work on Range. I've been having an intermittent no crank no start with my 2007 civic. Some times it'll start 20 times in a row and then all of a sudden nothing. Everything looks normal. It's weird. Any thoughts?

i have the exact same problem but my bolt is present. ive been having this problem for about 2 months now. I just connect my OBD2 scanner everytime I use the car to make it run😢

How did you pull up the diagram of the all those circuit? Was it through the scanner? If so, what scanner is it? Seems pretty useful.

So all you have to do is power pin 14 with pin code greeter and check pin 4 and 5 to see if they need to be grounded. Locate the G101 sensor at the rear of the engine with the yellow, brown, and black, to it to see if it connected at the engine. If not, check to see if it is missing a bolt. If so get a washer and bolt. Use a ratchet to attach it and wrap the wire around it.

my 2008 civic with 1.8 is slow cranking and I replaced the battery and it stopped but started doing it again and it does it in the morning or if it's sat for a long time, any suggest would be appreciated

would this ground cause civic to surge? i rule out all fuel issues aready, now it's back to square one grounding and electrical

I change the motor also and this didn’t work for me and all grounds are there

Buenos donde hay q colocar los pines
