View Full Version : Need help, no spark???

04-25-2010, 01:37 PM
I have a 2000 x1 that I can not seem to get running. I have no spark when I crank the motor over but when I use my laptop and run ecm spy I can test the coils and there is plenty of spark. I thought I might have a bad ecm so I replaced with no luck. Could this be some sort of safety issue which is telling the ecm to not sent a spark for ignition? I'm at a loss and not sure where to go from here and ideas or help would be great full.

ur wires;

new ecm; connected to coils; to wires/plugs= elec spark

good plugs? good wires? good coils? new ecm.

under load (starting the bike), the wires could be grounding out the elec, instead of sending too plug.

I'd check the cam position sensor. That's what tells the ecm the tell the coil/injectors to fire. Since ecmspy can make the coils fire I would say the coil side of things are ok. I would also disable all the safety switches. They could be telling the ecm not to let the coils to fire too.
my 2 cents, Matt

Thanks for the help everyone, turned out to be the kickstand safety switch. So now I have it running but running like crap. It will not idle, if i hold throttle at like 1000rpm it pulses between 1000 and 1500 if I take it up to 2500 it seems to stay steady. I'm trying to reset the tps but when I adjust the idle set screw the values on the ecm spy tps% never change. Could this be a bad TPS sensor? Is there anyway to test the tps? If it was bad wouldn't it show up as an error code on ecm spy? Any thoughts?

Did you click the key icon in ecmspy?

sounds like intake leaks; they always run better at high speeds
