ok folks, I'm new here and just wanted to get some advice and see if I'm on the right track or missing something.
Story goes like this, '08 SG had been sitting for about 7-8 months. "Ran fine" before it was parked and now it won't start.
What I've looked at: diagnostic codes
Are for TPS and TGS range, high and low.
ECM Battery voltage high and low. I have cleared the codes and tried starting again and no codes appeared after trying to start.
I have pulled the injectors, cleaned them and test fired them with a 9v battery. Work great and clean. I hooked the injectors back up the the fuel "rail" and the line to the tank and test fired them with the battery again. So now I know the fuel is getting from the tank to the injectors. Fuel pump works, hear it run when the bike turns on. Next I left the injectors out of the manifold but connected the plugs and cranked the bike over. No fuel came out. That's the fuel side of things.
Now the ignition. The spark plugs are new. I tested resistance of the plug wires and they both are roughly 7.5k ohms. I also tested resistance of the primary (pins C and D) of the coil and got 2 ohms the went primary to secondary (pin C to output to plug wire) and got infinity. Also pulled the plugs from the jugs and connected the wire and coil, grounded the plug to the side of the case and cranked the bike over and neither plug sparked.
So I'm thinking it's a coil. But the (EDIT) injectors are throwing me for a loop since no gas came out when I tried to crank the bike. And no codes for either the EFI system or the coil.
So what's the consensus?
