Well good and bad news. Good is mystery solved. Bad news is 100psi not enough to start engine. I put tablespoon stp thick oil in both spark plug holes, rose compression to 120, 125 psi cold. Plugs in and it started. Of course burning oil lol out of cylinders.
So, need rings and cylinder jugs it seems.
I bet someone ran this on low to no oil because low mileage 8,444 miles only…
Ih well.. thank you all.
Marcel, what is your email. I could use to try IAP, both and Engine Temperature sensor to try. They check ok, but im at a loss here.
Harness i would want exact model and year…
Spark blue white, also replaced entire ignition system plugs to wires, coil, pick up, alt, all in case, all were good and now all new.
No idea if new used ecu is good, but bike acts same, smell gas, spark, no start. Compression??? 100psi… cold.
No Fi lamp, that and tachometer missing. I rigged a lamp to Fi wires, jumped service mide. Light stays on, off as crank, on as ignition on. No blinks. Never off cause never starts now. Ran off on in past, weird. Seems like IAP?? Has correct voltage from wires to power and of signal range. Sensor, both have proper resistance.
Crazy.
Ok so got an ecu out of France, used, but most likely good,,, tried it, same thing. No start, smell gas have spark, low sompression, 100 psi.
So either wiring harness, or 100psi not enough to start?
I thought some engines has compression relief to turn over easier… will still start, correct?
Sensors all seemed to check ok. But maybe need to replace anyway IAPx2, eng tempwrature sensor?
Or is wiring harness issue
Baffled. I think it is flooded with gas from injectors on full?
And thoughts?
Where are you located in case parts may help me?
Which size engine?
What stopped this bike from running for you?
Update, purchased the flywheel puller and key. Pulled off flywheel, key was ok, not sheared.
So stil just cranks, no start.
Found a used, hopfully correct, hopfully working 2012 ecu in Spain. Hope to get and try in 2 weeks.
Aarrgg
Ty so much for info, esp in compression. 100psi cold might start……
Trying to find good used daewood ecu still, not sure if is answer.
My post shows most parts tried already.
Tomm i will pull side case off again to see if flywheel key may have sheared/ timing to spark…
Hoping it is sheared!
Will 100psi cold not start? This is only 7 kg cm2… 19 i Hot normal 16 low. But i am cold (not starting so cold…)
Ty for that. However tip over is sending signal. Also the neutral, clutch and side stand switches are all bypassed. Without bypass (or all switch in working order), the motorcyle would not crankover, which it does. Just wont catch/start.
Not sure if ecu needs to know these to run, but have fuel out injectors and have strong spark…
Just an update, i checked TP, both IAP, IAT, ET, idle speed sol, all have proper power and output range voltages. Wires to ecu continuity, but not checked to pins just strip wire a bit only..
No air leaks near intakes.
Hope to try a used alternate ecu next…
Crazy no start cranks well. Has compression.
Fyi, gear position (neutral also) switch i think does not work. This was jumped out to allow starter to crank. If this switch is not working, can it tell ecu to not let engine catch/ start? Engine did start intermitent before, this now, just crank only condition…
Still just cranks, no start, hear a few puffs, then none. This after new wires/ coils/ plug [resister] boots. New plugs, spark blue/ white esp w/ new plugs. Plugs gas soaked as pull out. Has good compression, new stator, new pick up coil. New intake air temp sensor. new battery. coils hv 12.5V etc…
So i suppose, could be iap1 or iap2 sensors, causing too much fuel maybe? or TP sensor, or isc solinoid?
cannot get any Fi light blink codes, light just stays on.
maybe ecu? hard to find one of these 2012 gv250 ecus. [not delphi]
timing or fuel mixture incorrect from ecu ng?
Ty, resistance was ok. I also did replace stator and pick up prior just in case…
I jumped dealer plug. No code or Fi blink codes seen. Fi lamp lights and stays on with or without jumped dealer plug.
Hoping new coils and resister boots and wires may fix spark again…
Ty. I did try stating fluid, no help, also smell fuel as trying to start.
I cannot get a blink code, Fi light just goes back on solid after crank and no start, never goes off.
I did notice less spark, yellow today as checking, then none, then yellow spark, then whiteish with out resister plug boots taken off. I ordered new coils and boots. Hoping it is intermittent spark issues… will advise back.
Has compression, both even, just says good ok on my elec version
Tryed new pick up, did not help, new battery also.
Weird, trys to start, spark, smell gas…, then just cranks, prob flooded…
Must be dam ecu? Aarrgg.
Yes blue white spark. Sometimes almost runs a few beats. Coils seem good.
I am going to try a new pick up sensor (2011 single 2 wire unit). I am wondering if gives spark but partially failing as to giving timing signals to ecu… can only hope. I took apart, fiddled a bit, back together then almost started for 10 fires or so, then nothing after a few more cranks.
Update, checked all connectors, electrical spray, all seem ok. Still just cranks, hear a little try only if open throttle just in option as cranking.
I have spark, i am going to replace the pick up for timing in alternator case, just to see if helps, even though it looks ok, has resistance and i have spark.
I have spark, injectors spraying, have compression, it can only be timing issue, or air fuel mixture off? All sensors ohm out good, voltage correct per manual values… i wush i could just try a new ecu, no wires look shorted to ground ect, all connected…
Aarrggg any help appreciated…
Thank you for this help.
1. So I have spark at both plugs, would that mean coils would be working?
2. Wiring and connections and maybe ecu is ok: It did try to start and even start, then not. So at least good news that ecu may be ok and connector maybe loose somewhere…
I guess i will just try to check any and all connectors…
Any futher ideas or comments are welcome of course… thank you.
