2014 GSXR750 won't run after ECU opened to cut new keys
I stupidly lost all of my bike keys (AU model with an immobiliser), so my only option according to Suzuki was to replace the ECU and all key barrels. I ended up calling a locksmith who was able to cut new keys and get the code from the ECU at a much cheaper price. The bike was running perfectly before this, but unfortunately it won't run at all now. It's a 2014 model, with less than 10,000Ks on the clock and had never missed a beat. Here is a timeline of events/symptoms:
1. While the locksmith was there cutting the new keys the bike started fine and seemed to run (well idle anyway) normally.
2. About an hour later I went to ride the bike home it was a bit hesitant when starting and idled pretty rough. After it warmed up, it seemed to go ok and I managed to ride it home (a 15min ride). It seemed a little off, but not too bad.
3. Two days later, I went to start the bike and it was really hesitant again and really rough idle once started (almost like running on 3 cylinders). I stopped the engine and since then I've not been able to start it back up again at all. It turns over and cranks fine, but won't start.
Getting spark on all plugs while cranking.
Assuming it was a fuel starvation issue, I've pulled the fuel pump out and given it a complete clean and replaced the filter/strainer pad and o-rings. The fuel pump is definitely priming before when ignitions is on. Fuel pressure also seems fine, if I pull the line off the fuel rail to the injectors, it sprays out.
The plugs were fairly dry though.. so it seems like the injectors are not firing. I guess I could try pouring fuel directly into the chambers and see if it fires up for a little while.
I did fill the bike up with fuel from a different place to my usual around 2 days before all of this. It seems unlikely but possibly it's a really bad batch of fuel.. I may try draining it and filling with new stuff.
There are no error codes. If I put it in dealer mode it just shows -C00.
It turns out the ECU had to be cut open in order to get the immobiliser key code. It was a readonly operation, nothing written back - but could this have caused any issues? Unfortunately I don't have access to another ECU to test.
If you've read up to here, thanks!
Does anyone have ideas or suggestions on what to check for next before having to take into a dealer/mechanic?
Has anyone heard of this happening after getting the key code read from the ECU?
