There's a much easier way to tell if your engine is getting fuel or not. Sense it's not running, if the fuel supply system is operating, then all of the fuel being pumped into the engine is not being burned. Therefor if your engine turns over for 15 or 20 seconds without starting all you have to do is go sniff the exhaust pipe. The exhaust will reak of unburned fuel that's being pumped into the engine, not burned, and then blown out the exhaust pipe. Hope that helps!
