a98pmalcolm Posted August 20, 2015 Share Posted August 20, 2015 (edited) Hey all. So I have an issue. My idle control valve is on it way out so I am replacing that when it arrives but I feel that that may not be the case here. On Tuesday I did a battery relocation, power steering res relocation and overflow tank relocation. When I had finished I started to have an issue with starting the car. The car wont start easily (most of the time) with out throttle assistance. This never happened before I did the work. Out of the many times I have tested how the car starts 1 time it didn't even start at all just kept ticking over. It all started as soon as I finished the battery relocation after the 1st start up. Can any give me any help or ideas? I have attached a video for you all. 1st time here was just generally trying to start the car. 2nd time as with throttle assistance In all cases you can hear the fuel pump prime no probs. Its like fuel or air starvation on ignition. [uPDATE] New ICV fitted. Problem is still there https://www.youtube.com/watch?v=m8or6h8v7GI UPDATE 12/02/16 Ok so today I had a free day to look at this issue again, some suggested Earthing issue, as other people on other car forums that have the same issue. So I earthed the hell out of the battery today by installing a 2nd earth and sanding the paint back to the metal and tidied some wires and still no luck. I am fitting a 170 amp alternator in a few weeks so I wonder if that will help. Any more advice would be fab, I really want this sorted Few pics from today: Thanks Paul SOLVED OK solved the issue thanks to all your help and Chaz. The issue was the power cable 0AWG amp cable juat wasn't efficient enough, I bought 415amp 60mm2 batter cable, heavy chunky stuff, and its now worked my issue with starting Edited June 26, 2016 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...

Fizzy T Posted August 20, 2015 Share Posted August 20, 2015 Have you checked what voltage you're getting at the end of the cable at the starter end? After watching the video I would also poke towards it being a fueling issue. Quote Link to comment Share on other sites More sharing options...

chazuk Posted August 23, 2015 Share Posted August 23, 2015 Is that the 10mm nut stock earth at the back of the boot you have picked up on? also what size earth cable have you used ? Quote Link to comment Share on other sites More sharing options...

Hi Chaz. Yes I have used the 10mm nut at the back of the boot. I also tried the rear seat bolt to the chassis, And then tried double earthing it using the rear seat bolt and the 10mm nut. I am using 0 gauge wire. Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted August 23, 2015 Share Posted August 23, 2015 Probably a stupid thing to say but I will anyway. Have you thought about moving the battery back to its original position and disconnecting the 0AWG cables to see if the problem still exists?

a98pmalcolm Posted August 23, 2015 Author Share Posted August 23, 2015 Hi Frank. Its a no go back mod. Wires have been cut off ect... Thanks for you input anyway dude. Its odd as its just needs the smallest throttle assistance to get it started. I have ordered different batter terminals that another member used on his relocation to see if that helps.

David P Posted August 24, 2015 Share Posted August 24, 2015 Nothing stopping you using jump leads to feed the battery to the original connections, then you'll know for sure if that is the problem or not. Quote Link to comment Share on other sites More sharing options...
FOSTA Posted August 24, 2015 Share Posted August 24, 2015 Sounds like it's got good connection to me as its turning over nice and strong! Quote Link to comment Share on other sites More sharing options...
David P Posted August 24, 2015 Share Posted August 24, 2015 I've come across this before, the starter saps the amps from the long cable leaving barely enough for fuel and spark. You may end up fitting another wire from the battery to feed them. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted September 2, 2015 Author Share Posted September 2, 2015 Small update on this. Before moving the battery cable to the starter I thought Id try a battery booster pack and the car started every time without fail. With the booster pack off ands its back to the normal problem so I dont think its the way its wired up, but could still be a ground issue?

Pudsey Posted September 2, 2015 Share Posted September 2, 2015 You have a voltage drop issue, in my opinion. Hence why the boosting pack allows it to start, bigger better battery is the direction I would be heading. You need one with more amps, which will assist the starting (eespecially when we get to the colder months). Hope you manage to sort it.

Chris Wilson Posted September 2, 2015 Share Posted September 2, 2015 (edited) Use a volt meter (multimeter) with extended leads to measure the voltage drop between starter terminal and battery + and engine block (ground) and battery -, *** whilst cranking the engine ***. If it's more than 1 to 1.5V on either you have inadequate cable or terminal sizes, or a bad ground to B- at the battery end. You should have a short thick cable from B - to a good clean metal ground by the battery, and something like welding cable between B + and the original positive battery cable under the bonnet. You can use the meter to test voltage drop across connectors and terminals, too. Red lead to B +, black to other side when testing the positive wiring. Opposite when testing ground wiring. What amperage / hour is the battery? ***** Note edit, I failed to state to test voltage drop WHILST CRANKING THE ENGINE ON THE STARTER MOTOR.

a98pmalcolm Posted September 2, 2015 Author Share Posted September 2, 2015 thanks for the reply guys. The battery is a halfords HCB005 start up power on them is510 amps I would have though it should be fine. Quote Link to comment Share on other sites More sharing options...

Dim Sum Posted September 2, 2015 Share Posted September 2, 2015 That's the exact battery I have too which I relocate to the boot. How old is the battery? Could it be the battery is on the way out? Quote Link to comment Share on other sites More sharing options...

Could it be the battery is on the way out? Halfords exchanged it a few days ago in case that was the reason. Quote Link to comment Share on other sites More sharing options...
