My super reliable 75' 1.8 now will not start. It has stock injection. I do have spark! Injectors show no fuel outflow when cranked. I then went to the pump and when cranking over it shows a steady low flow of fuel. Shouldent I see a pretty high rate of pressurized fuel given these are putting out over 20 psi? This is the original fuel pump.

Good eye. Yeah, it's a 400 four. My other project...
OK, if the coil lead is connected, you should verify that the injectors are properly powered by the dual relay. Also, the injector resistor pack leads will fail over time. (I carry a spare dual relay and injector pack with me.) And have you verified fuel pressure in the rail? This requires a gauge and some method of tapping into the plumbing, either with the fiddly little OE pressure port (good luck finding that adapter) or with an in-line tee fitting. Yep, its connected. BTW, nice bike. 400 supersport? |
