13 SG Crank and no start...help
I just got done with a 3k ride and she ran great. Got home pulled both front and rear tires. Had them mounted and balanced put them back on and no start. She cranks and no fire. I can hear the fuel pump prime. I disconnected the fuel tank check valve and reconnected, no go. I disconnected the power chip, no go.
Only 20k miles on the bike. Tomorrow I am getting spark plugs to check the spark. Is there a way to check the check valve to make sure fuel is going through? What could it be?? Fuel filter? Ignition coil? I will take any help as I have another ride on Sunday!! Thanx |
If there isn't enough compression detected, it will not spark. I just found this out while researching S&S EZ Start Cams.
Is there a clutch / kickstand safety switch? |
ckp sensor. take plug out lay it on head see if it sparks. if your getting fuel u should see it spray out plug hole. if u get spark and fuel it's crank position sensor

Fuel check valve is holding pressure and allowing fuel to pass Still no spark too...What's next? Spark cables? I'll test those... |
could this be the coil?
how do i check the coil |
how do know it's holding pressure u have fuel pressure gage? check coil with omens meter check resistance. mite get a shop manual it will tell how to check coil. try systems relay. it sends power to fuel pump coil injectors. see if u r getting power to coil.? I hade a car do same thing it was ckp. hope u fix it be for sundayhttps://www.hdforums.com/forum/images/icons/icon14.gif

bought a new systems relay, no go So this is where I was at yesterday before I got you message. Doing the typical fuel, spark, ignition... thinking. What was new to me was the CKP sensor (Thank you) I didn't know you wouldn't get spark if it were bad. So when I put the new sensor in and still no fire and no spark I was bumming pretty hard. This might mean coil or ECM. I went with coil first as your suggesting, and its not in the easiest of places! But I went to unplug it an see if I have power to the coil. I hardly touched and the plug fell out!!!! Now I have visually looked at this plug multiple times and it looked like it was plugged in, but it was in a such a small spot I never thought to get my hands on it. Could this have been it all along you ask!!?? YES!! Had to use a screwdriver to reach it and get it plugged back in, but she fired right up! If your asking how this could have happened... well the other day I was washing the bike and must have been when I was washing around the top of the transmission and nocked it off. Lessons learned once again. $6 really, $60 CKP sensor and some time and frustration, but still cheaper than a diagnostic test at the dealership. Thanks for the help! Huddy |
