5pw wiring
Beamerboy - 14/3/19 at 06:14 PM

Hi after a bit of advice for my r1 build

Briefly I have a 2002-2003 5pw engine and loom fitting in a kit car , I donít have the clocks as using a digidash instead neither the ignition barrel and key but everything else present

I had the problem fuel pump ran but no spark fixed that by earthing the black cable in the ignition switch the alarm cable

That all works but still no life of it starting , I have bridged the black wire and blue and yellow wire also on the ignition switch loom as recommend this also. But still nothing

Am I right thinking imobiliser is stopping it still is this in the clocks as thought or is it actually in the ecu .

After any advice where going wrong to get it running or what wires Iíve missed to prevent it starting

Oh and also the red and brown which is the ignition switch is ran to a push button start which all works correctly and as should mention this Incase it may have a bearing on the issue.

Any help much appreciated and thankyou in advance

Tilt switch or neautral switch??

Tilt switch still connected as is , neutral switch still connected as per loom with dash neutral linked in also , I did disconnect the neutral switch originally and that killed it completely so re connected it up

Tilt switch in the correct position?

Yes with up on the top fixed dead plumb too

I have a 5pw r1 and did once have a weak fuel pump. With it cranking look directly into the throttle bodies can you see it physically squirting fuel? You can slide up the diaphragm as it's cranking to have a better look.

I will look tomorrow as battery flat now hoping it would get fixed by the fairies lol , I can smell fuel through the exhaust so seems to be coming through but I will check that

I am using an external fuel pump that is speced up same as the r1 original , and when switch on ignition it primes , tried it also disconnected from fuel rail and pumps really well in fact it p***** through , got great spark also checked that too.

I have a custom hilt 4-1 exhaust without the exup part in the exhaust would this cause anything I do have the expo sevo plugged in and works when start up ignition hear it setting up etc but not the part thatís fitted to the exhaust

Thanks for the comments so far and your help itís much appreciated

Just checked and not getting fuel in the injectors fuel pump priming , it seems the fuel system is shut down on the ecu and not having clocks cannot reset the fault code Iím guessing itís flagging up

Is there any way round this to trick the ecu to think all is fine or is it a case of sourcing clocks to reset the fault code that way

Thanks

I have to be honest I didn't think the engine would need clocks to run. The best place to ask would be on this forum as they use the 5pw engine in Minis http://www.pro-motive.co.uk
Your next step now would be to put a pressure guage on the end of the fuel pump and see what it's producing while cranking think it's roughly about 40psi

Pump is fine and all working and getting spark , Iíve got to the bottom of it with another builder , whatís happened between the bike being stripped and me installing it the ecu has flagged up something not right and has shut down so itís the injectors not working or anything to do with the choke throttle flaps etc this is what the ecu has shut down .

The fix is plug an original dash off an r1 ( which I donít have lol ) and basically switch it on fault code will come up reset it off the dash and then good to go all being well

So now on the hunt for a cheap set of clocks which could take some searching as e of the bay silly prices for what I need it for so the search begins

Thanks for the Information also great to see people help out its much appreciated
