VZ250TLR Mfg date 11/06, ~140hrs – The engine will crank over, but will not fire. I’ve checked for and have spark on all cylinders using an inline spark detector. I have gas in the cup filter under the cowl. With the cowling off, I don’t hear any pumps pressuring up the fuel system when the ignition switch is turned on. I put my ear to the VST when an assistant turned the key on. What can I do to troubleshoot the fuel system to make sure it is getting to the injectors and they are firing?
