400 cranks but no start
K4 Burgman 400 with a problem. Recently procured from a friend, she's been sitting a while. Picked her up cheap because she won't start. Figured I could try my magic touch and see if I could resurrect her from the dead. So here's the low down: She cranks fine, but will not fire over. I have:
1. Drained fuel tank of all old fuel.
2. Checked fuel injector nozzle and cleaned.
3. Fuel pump works fine and pressurizes injector.
4. No computer codes displayed.
5. Checked for spark.
6. Compression blows finger off of spark plug hole, although I have not actually measured it.
7. Checked fuel injector solenoid action (clicks with a battery); does not squirt when cranking.
8. All fuses and relays are good.
9. Battery is good, tested and charged.
To the best of my knowledge, what I seem to not be getting is fuel. I have removed the fuel injector from the intake and cranked the bike to see if I could see a fuel spray from the injector and I do not. From what I have been able to spray into the intake of starting fluid, this is also not enough for it to start, or even blubber for that matter. So having spark and some compression the starting fluid didn't make it catch; although I had to remove the world to spray it down there, so it may have evaporated before I could get her cranked over.
When it cranks, it also seems to crank slowly. Although I must say, I've never owned a Burgman, so this may be normal, but it just seems naturally "slow" to me compared to my other bikes. At first I thought maybe the starter was going out and had an internal short drawing too much current, but even with a piggyback start from a car battery the cranking does not increase in speed and the voltage does not drop significantly from the battery, so I don't think this is likely. I tried measuring voltage at the fuel injector, but of course to the best of my knowledge it's operated on pulses, so my readings probably meant diddly squat. But I did see SOME voltage there when cranking.
I've tinkered with it off and on for about a month, and I'm nearly at my wits end. Any ideas or suggestions? Bad ECU?
