Hi all,
Am having a little trouble starting the battlestar and thought someone might have had similar and might shed a little light before I rip the pump out, the fuel pump seems to take a little longer to prime than it used to (might be my imagination) but sometimes it winds and will not start but the minute you let it reprime it fires straight up. No consistency except that it seems to be a narrow window when it will start, if its 75% way through the prime or if you leave it for a couple of seconds after prime is complete it wont fire. Am thinking there is a lack of pressure due to pump being weak or passing somewhere ? Possibly regulator? I have the wire holding the reg and pump together so I presume its not that. Was looking for some wisdom before I pull it apart.
Thanks and have a good weekend
It does sound like the regulator doesn't it. Best ya check the wire holding it, wonder maybe if it broke or came away from where it was put.
Sounds more to me like a blocked teabag / gummed up fuel pump, and its taking a bit longer to inject enough juice to get it started. Doubt its regulator, as that cause more a flat battery problem. This sounds fuel related.
Could also be gummed up injectors, but I think the fuel pump / tea bag is a better place to start.
One thought - it might be the pressure regulator clip coming loose - see this thread. Easy fix. Worth doing whatever anyway.

If not and you need to clean your pump etc, these threads may help

Horse, first check is battery voltage while cranking. Stick multimeter on, at least 9.5 cranking.
Further thought (prompted by grog's response) - check the earth cable from your battery is good and clean where it bolts to the frame - sometimes these get a little rusted/corroded.
As
@gsxbarmy says check your earth's frame ,battery and motor as the only time my bike had starting problems this was the fault .
Good luck hope you get to the bottom of it soon .

Thanks for all the replys ,cleaned the primary and secondary filters when I wired the regulator up about 2 months ago, would be very surprised if anything's blocked up , plenty of erglatrons getting through but will check the voltage to be sure. Once its running everything is sweet, I run injector cleaner and meths through the tank at regular intervals and would have thought injector issues would manifest itself at idle as well ? I will check the earths but would think unless it's an earth connected to the fuel pump and the pump voltage was affected it wouldn't affect the pressure . It feels almost certainly fuel related the way it fires up so I am going to try and get time to pull the pump this weekend if I get the daughters car done,
Thanks again for the directions
Just a follow up ,checked voltages all good ,ripped the pump out all clean nothing amiss all o rings tight and in good cond generally I have found nothing so regulator aside which I couldn't test I could not fault anything so I will just wait till something develops , thanks to all that offered advice
@horse Take a look at the workshop manual on page 8-4 if you haven't done so already. Might give you some ideas where to look next.
@horse What Perth are you at as if it the Scottish one I have parts we could swop to fault find on your bike .

Horse is in the southern hemisphere Seth.

@KiwiCol It just says Perth on his profile and I'm only 20 miles from the original Perth lol.

Thanks for the offer Seth but this Perth is just a little far out of the way I am going to check the pressure when I get a decent gauge but I am resigned to the fact that the pump is on its way out unles the regulator is playing up which on a simple device like that I am doubting anyway have checked about as much as I can at this point ,it's starting OK at the moment
Thanks for all the suggestions
