Hi guys,

After being away for 4 weeks I've come back to use my FK1 and unsurprisingly the battery was dead. I then jump started the battery using another car and let the car run for about 20 mins. I checked immediately after turning it off whether it would start up again and of course it didn't.

10 hours later I've gone back to use the car which still had a flat battery. I again went to jump start it but this time around the car constantly turns over on crank and won't start up. The alternator has been checked and it is supposedly charging the battery.

When I stop cranking it says 'Please check system' and shows the battery symbol.

Do we reckon the battery is just completely gone? Even if the battery was very low surely it should start with another vehicle jumpstarting it? Or am I mistaken?

Any help would be massively appreciated!

Nope the keys weren't in. I connected the donor car while both were off and then I started the donor car let it run for about a minute and then tried starting the Civic to no avail. This is so frustrating :(
The battery is over 2 years old and Halfords brand :/

sounds like the battery to me, a flat battery will not charge up fully, if you get it started, and run car for half an hour or so, still wont charge up fully, take it off and fully charge with a charger, hope this means sense

It's my experience that the car should jump start off the other car as you are effectively using that battery power, the only things I can think of;
Are the jump leads good quality and connected correctly, have you cleaned the terminals etc?
Is it flooded? - In which case keep the throttle fulling to the floor while cranking?
Is there fuel getting to cylinders? - Not sure if it's diesel or petrol, if diesel pump the fuel primer/bubble in engine bay until hard.
Is the immobilizer turning off correctly? Did you open the car by key fob or key?
Obvious things, assure all lights are turned off including interior lights while trying to jump start.

Hope it helps if you haven't already tried any of this.

I agree but it's worth mentioning as someone may have whacked the dash in frustration! Or slammed the door, etc.

With the car hooked up to another battery/jump lead to another vehicle I'd: check for a spark, pull any plug lead from spark plug and stick a spare spark plug in lead, then crank engine over. If spark visable, I'd take off air filter cover and spray some easy start down air intake when engine is cranked over (replace plug lead )

Good call, or they could just be fowled up now through continuously trying to start it.

The jump leads are of very good quality.
I tried putting my foot down while cranking.
There was definitely fuel coming through.
As for opening the car I had to use the key because the I couldnt use the fob. Would this be a factor which stops the car from starting?
I'm also going to buy a battery charger while I'm at it just in case.

Possibly, have you tried once the car is connected to the other car via jump leads, locking and opening the car with the fob and try starting then? Hopefully the other battery connected to yours will allow you to do this as it may be an alarm/immobiliser stopping you starting it.
Fingers crossed.

How have you connected the jump leads?
Does it really make a difference, other than for safety reasons, being that you are less likely to get a short. There is no electrical circuit between the two cars and no current can flow until the second lead is connected. I can't see that it makes any practical difference (other than for safety) which order you connect the duff battery to the donor car.
If there is a good scientific electrical reason for doing it the way Honda tell you to (positive first), please inform me without any safety based mumbo jumbo.

I was merely finding out if the neutral was connected correctly to the host cars grounding point and to the donors negative terminal. A lot of modern cars dont like being jumped with leads straight to the battery on each one and it usually fried either a big fuse to protect the ECU, or in rare cases the EU itself.

If its the first one, i would be checking all fuses to make sure one hasn't blown.

Ah, right, I see the meaning of the question now.:eek: Where you connect the connections to, is possibly important for the reasons that you give.

My manual says connect the neg to a specific engine mounting stud, (and so does the one for the G10 Civic) and not the battery neg.

I was meaning the order that you connect the leads. Pos first or neg first.

Years ago it was always battery to battery but more recently I've seen advice to connect the neg to a body part.

The 2017 Civic US HB gives instructions to connect the neg to a specific engine mounting bolt with the warning 'Do not connect this jumper cable to any other part'. So not just any old mounting bolt, but it doesn't say why.
