    This was my post from yesterday i had made regarding the problems i have been having with my bike regarding no start and erradict starting.

    "Well all i got my bike finally started last night and rode it around for a bit but when i parked it for the night last night and tried to restart it today it wouldnt start. Im still getting no spark on plug 1 which had it as i watched it spark last night and the bike fired up. I dont know what i did to fix it but all i know is that it def is a spark issue
    causing the issue as no blue spark can be seen when turning the engine over. Also a weird thing that it is doing is the rpm gauge needle jumps around to redline and back down when hitting the start button and sometimes with just the Ignition turned to the on position with the key. Anyone have any ideas as to why my bike is acting so erradictly?"


    Now today i tested both ignition coils and the pickup coil, cut the plug wires back to check for a good screw in connecrion and changed plugs to no avail. Everything came up within the ohm specs as listed on various xj forums i searched so where should i go next to look regarding no start on all 4 plugs it seems as i tested all plugs grounded to engine and none sparked :/

    If it was running yesterday and now you have no spark at all, I would first check the kickstand switch. I don't know if a fuse would cause this problem but someone will.

    Fuses are all brand new blades all well to do inside and connected well and my sidestand switch has been bypassed a while back before i bought the bike.

    Check the voltage feed to the TCI and to the primary side of the coils.

    Okay thanks k moe i just have no clue now because all ohm readings came back into specs but i didnt try voltages, is it the same for the tci pigtails and theprimary coil pigtails testing as is testing for ohms or is voltage testing for the two units a different process?

    To get it to run the other day was magical i feel because all i did was check the connections for a last time, took the plug number 1 plug out of the cylinder with boot on and grounded it to the motor and cranked it over to see a blue arc jump it and it fired up and ran fine that night for about 20 minutes around town for a test ride until i pulled it in for the night and the next day the same problems arose again im having now. No rain or nothing the night before either

    Check that the bypass is still solid just to be sure.

    Nvmd you mean the ss bypass, if so i already did one step ahead of ya i guess lol it has too female connectors looping it as a circuit right below the battery and the other connector just hanging like it always has but ive never had an issue as of yet in 2 years with this bypass

    Pull the Side Stand Relay to bypass. Then it won't matter what is going on with the switch or wiring that controls the relay. The TCI will be enabled with the Side Stand Relay pulled. Option two, follow the B/W wire on the TCI 6 pin connector, should go to a bullet connector, disconnect that and the side stand safety will be disabled.

    Note: bypassing the side stand safety circuit should be for troubleshooting only. Any fault with the safety circuit should be corrected to ensure rider safety.

    To rule out a problem with the side stand safety circuit disabling the TCI (no spark) either disconnect the B/W wire at the bullet connector or remove the Side Stand Relay. Disconnecting the B/W wire would be the preferred method if the PO has already attempted mods to disable the side stand switch.... not knowing what else might have been attempted.

    Okay i will try all that but what i find strange is how the bike ran fine with the old mod and then just stopped all the sudden the next day with no spark and no start.

    That is the nature of the intermittant electrial fault. That is how I used to spend most of my time when I was a maintenance tech; finding the stupid little things that kept the quarter-million dollar machines from working.

    Right i understand k moe i bet lol i wouldve thought it was just a wire loose though if i had to guess but i checked them all and the fuses all were connected, none missing or anything and my killswitch works as well i took it apart and cleaned it. The ss relay bypass has never caused me a problem like i said but i did check it and all is tight with it.

    New problem arose in which i found weird as well. Tinkered around on my bike some a little bit ago i took a look at the flasher relay and for the hell of it took it off and attenpted to start the bike in which the bikechoked a few times then died and would not start back up again after reataching the relay and all. The blinkers themselves are all flashing at once though i found as well which could indicate a problem i feel. I do have aftermarket leds but did the relay swap out for a new one and took the indicator bulb out which it worked until i saw the issue now along with my no start problem. Could these problems be linked?
