Hi all, first time happened about a week ago, start bike, idle starts to go up for a split second as normal then dips straight back down to below 1000rpm, PGM-FI light flashes twice every 3 or so seconds, continues for roughly 30 odd seconds till the bike cuts out. (PGM-FI orange one, looks like a motor, right side) if i try to re-start straight away, it wil not start at all. if i turn the key off, then back on, starts up fine, idle's properly. run's properly while riding, no problems what so ever. 1st visit to honda last week, they only found a ABS anomaly and asked if i wheelied often, i replied no, never which is the truth !! they found no other anomaly when the bike was hooked up to their honda software.they told me to go home and see if it continues. 2nd visit to Honda this evening (20 min after it had did it again leaving work) and when hooked up, no anomaly detected, ( software see's my bikes id but does not see it as a vfr800, weird ) . so they kept the bike and loaned me a 2015 cbf1000 ( not my style but hey ) sometimes it does it morning and evening, sometimes just the evening. if i stop somewhere for a short while, it runs fine after too. Bike has almost 20 000kms. still under warranty till April this year, and it's a 2014. it's got an arrow end can with the db-killer in, and a techno-globe alarm, both since around 4000kms till now. i always fill up at the same station, and always put only 98 unleaded in; as the euro french manuel advises. the battery is in good health and is hooked up to an optimate if i know i will not be riding for more than 2 days. one of the Honda mechanics said it could be (i'm translating from french here, not sure what the english equivilent is) atmospheric pressure sensor in the fuel injection . so we'll see what happens, will keep you updated. take care .

My 98 VFR800, my daily driver-commuter bike with about 45k miles, has developed an issue and I'm hoping someone might have some insight that I've overlooked. On the way to work the other day as I was coming down the off-ramp, the FI light came on and the engine stalled. While coasting I pulled the clutch lever and tried to restart it, to no avail (starter turned, no ignition though). I ended up getting a flatbed ride home and started checking the usual suspects--fuel pump relay, main engine relay, relevant fuses, etc. I checked for voltage at the fuel pump, none, although the engine and fuel pump relays were clicking and sitting voltage was 12.1 volts. I also put the bike on the charger just in case it could be a low voltage situation but I was doubtful since it cranked so healthily. Just in case, I also put power directly to the fuel pump and it whirred solidly (and right after I plugged the harness back in the bike fired up for a one or two seconds, but probably because it had just enough fuel in the lines). I had a spare new old stock kill switch so I replaced that as well but no change. I tried a second bank angle sensor but no change. I've checked the side stand switch and that looks good (though a bit grimy). A couple of years ago, after having dealt with far too many R/R failures I put in a VFR-ness, a Mike's R/R, a fresh stator, and a dedicated fuse block for accessories. I hadn't had any further electrical issues until now. The grounds are all tight and based upon voltage measurements and the fact that the bike cranks so well, I'm inclined to believe the issue may be the ECM/ECU or harness, though based on my research, those don't fail very often. I also checked for codes but got nothing, FI light stayed solidly lit. Sometimes when I turn the key or toggle the kill switch (which I don't normally use) I hear the pump prime for a fraction of a second and sometimes if I toggle the kill switch to off, then hold the starter, then toggle kill to back on, I'll get a sputter (actual ignition) but no continued running and it's not consistent when i try this. I have a new fuel pump relay en route, just in case the actual installed environment is different than the test environment. The FI light stays on when the key is turned, both the engine and fuel pump relays click (measured voltage and felt each clicking on). I doubt it would be the ignition switch since power is getting everywhere else but like I said at the beginning, if anyone has any other suggestions of something I might have overlooked, I'd appreciate hearing from you. Otherwise I'm leaning toward hitting eBay for a used ECU/ECM...
