rbig1 Posted September 11, 2014 #1 Posted September 11, 2014 well when bike is running pump looses power to run. only has power when switched on before starting then after engine dies. what relay controls pump is it the blue connecter for ignition. also its hooked to tip over switch, kill switch, side stand switch. do I have this correct. and any one have a readable wiring diagram colors and socket wire locations.
Prairiehammer Posted September 11, 2014 #2 Posted September 11, 2014 Rodney, It sounds to me that the fuel pump relay is not getting the signal from the Ignitech that the engine is running. The fuel pump will have power for five seconds whenever the main switch (ignition key switch) is switched to ON. After five seconds the power to activate the fuel pump relay is switched off unless there is a signal from the TCI that number 2 cylinder is running; the number 2 pickup coil. Perhaps, Dingy can help diagnose this problem, if it is a Ignitech settings issue.
dingy Posted September 11, 2014 #3 Posted September 11, 2014 Ignitech TCI is not tied into fuel pump on 83-89 models. On 90-93 Ventures, it does control fuel pump. Gary
utadventure Posted September 11, 2014 #4 Posted September 11, 2014 Wasn't the bike running (maybe not how you wanted) before you made changes to the TCI? Or are we talking about two different bikes? If it's the same bike, try resetting to where the TCI was before and see if the pump returns to activity.
rbig1 Posted September 11, 2014 Author #5 Posted September 11, 2014 thanks Kevin. I think the 83 year ran off wire to #2coil. was reading another post. but they never said where, and they were working on a 86. I have left fairing off. just not sure where wire hooked into coil wiring and color to relay. I believe dingy said igntec couldn't supply enough voltage to run pump. don't know if it would activate a relay to power pump tho. and if tip over would shut it off hooked up that way. taking laptop out in shop with me connection isn't to strong but works. I don't think this site auto updates while using. but will keep refreshing it. nothing else wont be lonely.lol:hurts:
rbig1 Posted September 11, 2014 Author #6 Posted September 11, 2014 well tested blue/white wire at relay has 12v when not running then nothing after engine running I thing if I am reading diagram correct also in repair manual says there are two relays by headlamp am I reading this correct. the blue and black wire is 12v not running then after starting auto ranges from 25. to 12. maybe that's how it supplies voltage hit and miss. this wire goes to pump. the red and white wires go through coil and solenoid maybe this isn't my problem but pump runs quite a bit after it dies. im thinking there were quite a few issues wrong and having to work through them. I have a extra fuse think I will hook pump up that way and see if it dies.
Neil86 Posted September 11, 2014 #7 Posted September 11, 2014 Rodney... On an 83 the fuel pump wiring is different....I have an 83 service manual. The #2 firing was on later models....on an 83 you have 2 red/whites wires for power in (after engine stop (aka kill switch) 1 blue/black for power out to the pump. 1 blue/white over to tip over switch. The relay should be on "relay row" on the left as you face headlight. If tip over switch is activated it closes, blue/white goes to ground, opens fuel pump relay cutting off power to pump.
rbig1 Posted September 11, 2014 Author #8 Posted September 11, 2014 well been running this whole time and there was no sluggish range in throttle. so I know this is the problem just where
Neil86 Posted September 11, 2014 #9 Posted September 11, 2014 Test the voltage while running on the red/white at Ignitech (8 wire plug) and also at fuel pump relay. They should be at battery voltage.
rbig1 Posted September 11, 2014 Author #10 Posted September 11, 2014 well I have 189 ohms in the blue wire. and I did dump it in parking lot quite a while back. kind of strange as rode it all over since then. is this sensor below dash mounted to plastic shield. there is also a big square one in there same area but its just hanging there. my pump relay is on the opposite side but all hangers are broken how do you fix this or have to replace it.
rbig1 Posted September 11, 2014 Author #11 Posted September 11, 2014 Test the voltage while running on the red/white at Ignitech (8 wire plug) and also at fuel pump relay. They should be at battery voltage. they both were above 12 with bike running.

Rod, The tip-over switch is pictured below:
Neil86 Posted September 11, 2014 #13 Posted September 11, 2014 Okay... bike running and pump getting its power only from the relay theres 12 V on the R/W?
rbig1 Posted September 11, 2014 Author #14 Posted September 11, 2014 mine is mounted straight up but same area. will give it a few taps see if it makes a difference. had to stop working on it for now. but if I understand correct red wires are for pump power and other to power relay. blue and white grounds relay which cuts off power to pump
Neil86 Posted September 11, 2014 #15 Posted September 11, 2014 (edited) 2 red/whites 1 to relay contacts 1 to relay coil The relay is normally closed. When the coil is grounded through blue/white to tipover switch relay opens killing power to pump. The blue/black is power out to pump. If you are asking about fixing the hangers...I just reset them on the frame tangs and ran a few wraps of electrical tape around the hanger. Edited September 11, 2014 by Neil86
Neil86 Posted September 11, 2014 #16 Posted September 11, 2014 You can as a test temporarily unplug the tipover switch, bike will operate fine without it, but of course will staying running if tipped over.
rbig1 Posted September 11, 2014 Author #17 Posted September 11, 2014 will try this tomorrow unplugging tip over switch. is it possible to take it apart and clean out. going to add a short piece of wire to pump power side. so when it does this again will be able to get home. may even wire to extra in fuse box just leave fuse out. have to stop for now and get rubber balls out of furnace they went all the way down pipe. forgot to put register back on after replacing trim. wife wants heat now.
rbig1 Posted September 13, 2014 Author #18 Posted September 13, 2014 well tip over made no difference. so i unplugged relay with blue connecter I think its side stand switch. will stare at wire diagram a while longer. I believe its a normally closed relay on both circuits ie fuel pump and side stand.
rbig1 Posted September 13, 2014 Author #19 Posted September 13, 2014 the black and white wire on 6 wire plug on tci should it have 10 volts with bike running. I think it is hooked to tip over and side stand. according to diagram that would disable fuel pump relay.
rbig1 Posted September 13, 2014 Author #20 Posted September 13, 2014 I disconnected black and white wire. fuel pump runs all the time. kill switch still works. side stand don't kill bike. so t/o switch probably disabled also. but side stand shows in cpu when down. did tci go bad?? I noticed the setting says yes to fuel pump been that way whole time though. never changed it didn't seem important.
Prairiehammer Posted September 13, 2014 #21 Posted September 13, 2014 If I remember correctly, the side stand switch has two contacts. Possibly, one set of contacts is working properly but the other is FUBAR? Also, some have 'jumpered' the side stand switch so that it still shows as down in the CMS, but it does not kill the ignition. Perhaps someone did that to yours.
rbig1 Posted September 13, 2014 Author #22 Posted September 13, 2014 (edited) I fixed the side stand switch when I first got bike had a habit of forgetting stand down made sure it killed bike and it still worked before I removed wire. the other thing I just did was remove factory boost sensor. never unplugged it till now. according to diagram not connected to this wire. I did clean all plugs in wiring. maybe they just got contact. if fuel pump ran off this terminal that would shut off fuel. no that would short it out Edited September 13, 2014 by rbig1 add correction
rbig1 Posted September 14, 2014 Author #23 Posted September 14, 2014 well let me recap today. jumped relay connecter pump runs fine. put relay back in works when bike not running. disconnected tip over switch pump still don't run with engine running. disconnected side stand relay pump still don't run with engine. pulled black and white wire on computer pump ran with bike first 5 times. then problem came back went into computer turned off fuel pump setting no difference. tested voltage at both sides of fuses good. still don't know how it knows bike is running. throttle switch for killing bike works for on off of pump while bike not running
rbig1 Posted September 14, 2014 Author #24 Posted September 14, 2014 5-5-11 dingy you replied to a thread with pictures of a 83 fuel pump relay. I been testing the wrong relay if it is supposed to be the 1.5 square relay aprox and flat. the manual showed two for pump but wire colors are different will try to take pictures tomorrow and post.
rbig1 Posted September 14, 2014 Author #25 Posted September 14, 2014 any one have a relay looks like a tf307
