R1100gs wont start after chip install.

[pieter.oneill]

Hi all im new to the gser Forums but have found the threads and previous advice most useful however im scratching my head with this current one. Ive got a 96 1100gs all was running fine but i had read up about the john Gemi chips and thought might try one of those see if i get even better running (it is Decat and has a lazer exhaust with k&n air filter) all this was from the previous owner. Anyway chip arrived and i followed to procedure to install the chip then started the bike....heard the pump prime then turns over but wont start then i see fuel dripping out of the exhaust so flooded, anyway contacted john for advice but I've not heard back so i thought right ill put my original chip back in as all was working fine before, i did that this morning and then same result. I've got fuel getting in so thought ok no spark but I've took plugs out and checked them both sparking lovely, checked injectors no blockage holding open, so i have good compression, fuel and spark i should have a motorcycle firing up if my years of fettling in the garage serve me correct? i did read on the hall sensor connector thought maybe id unplugged or disturbed it but all looks fine with that no wires frayed or damaged. So if anyone has some suggestions they could throw my way ill give it a go. Cheers All in advance

Ps. sorry if i have posted this in the wrong place or its been done before im new to Forums.

Did you re-seat the throttle cable properly on the RH throttle body after you replaced the tank? If it’s displaced the bike will be reluctant to start. Also you should do a TPS reset really - pull the motronic fuse, replace, ignition on, open throttle fully a couple of times. Ignition off. Then try to start it.

Cheers for the reply sproggy I checked the throttle cable as I'd seen mention of that a few times but have i not tried that tps procedure you mention I shall give that a go later when I'm back in the garage and let you know if there's any change

 

[pieter.oneill]

No such joy with the tps reset but rules another thing out. Engine turns over great it is as if it is either getting to much fuel or is sparling at the wrong time, my worry is fitting the chip to the ecu has buggered something uo inside there. As mentioned bike running fine before and I was riding it the morning before putting the chip in, only see positive reviews about the chip online but that's the only change I made before this issue.

Revisit everything you did electrically in the process of replacing the chip. If you removed the ECU connector, remove it again and check all the pins are securely locked in position. It is possible that when you refit the connector an unlocked pin is being pushed back.

20 odd years ago I seem to remember when I installed a performance chip in my 1100GS I had to remove the beige coding plug from the fuse box, leaving it in gave the same symptoms as you are describing.

 

[pieter.oneill]

Cheers guys, interesting you mention about removing a beige coding plug, i don't see one of that colour in the fuse box, but the last message i had off john was "can you send me a picture of the fuse box" so maybe he was looking for that. Ian i was extra careful and double checked everything when i put my original chip back in as i thought a similar thing. Now since the last message i was trying all sorts and disconnected both injector plugs to see if it would try fire with what little fumes were in there and it did well at least for 3 seconds but it didn't fire at all before just turned over and got flooded, so injectors plugged back in full advance lever on and she started to fire had to give her a bit of throttle too, usually its just press button and she fires right away. kept her running for a bit and she idled fine once slightly warm I'm going to let her cool down and try again from cold, as i didn't actually do anything that i can say ah that was the problem im reluctant to head out on her but ill see what happens on a cold start in a bit. Really appreciate the help an advice, my own fault for playing around in a way as the bike runs great.......just cant help fettling in the garage haha.

Peter,
You did make sure to put the Eprom in the correct way round (taking care to get the notch in 1 end to match the notch in the socket)?

 

[Paul G (BHT)]

Go and pull this out then try and start it..... come back and tell us what happens.

[pieter.oneill]

Yeah i was up on the notch matching even took pictures so i didn't question myself after. Well i just went and tried a cold start and she's fired up on the first press just as she did before all this started. I do have the yellow plug you show in the picture but have not pulled it as its all up and running now, what does it control out of interest? I do however have a dilemma, do i leave it as is and just use it as i have been with no issue and leave the john gemi chip in the draw.......or do i put the gemi chip back in armed with new information from you lads and try again hmmm ill have to see if the intrusive thoughts win.
Really appreciate all the responses by the way lads taking the time to share the knowledge. cheers

Hi Peter,
The CCP is a coding box (Same layout as a relay, but with just links inside) to allow you to select for different fuel grades dependant on where you are in the world, this rural Africa etc.

 

[pieter.oneill]

Cheers Neil that's interesting might pull that tomorrow just out of interest and have a read up on it. It's my first gs and I do enjoy the simplicity of working on it a bit like my harley everything is there to get at i have had newer bikes but I'm just always drawn to the character of the older ones. It's done 114k and pulls strong and has never let me down.....untill I mess with it.haha

Pull the plug and stick it in your tool box..... then fit Johns chip and have fun.

My 1100 did over 60k miles with no plug fitted after I replaced the chip in the Motronnic.... that was with fuel from all over Europe and North Africa.

 

[pieter.oneill]

Paul that's all the encouragement I needed to get back in there haha I shall give it a go over the coming week and post what has happened, read up more on the ccp and it does sound like that needs removing as well as fuse 5 pull and a tps reset so basically all of the advice recieved. Thing is the chip from john gemi in a jiffy bag an that was it no note, basic instructions anything saying that for 80 quid maybe that's all you get. Cheers all

 

[ThreeDawg]

I don't have my 97 1100 to hand right now, it being on the other side of the world an' all, so I don't know what colour any plug might be, but the coding plug thing interests me. On my trip to South America last year the bike stopped three times in extreme heat/altitude/shit petrol scenarios. It has a Gemi chip in it, and I wondered if the chip didn't play well with poor quality fuel - it never stopped running with 'Super' in the tank, only 'Corriente', but maybe it just needed a different plug.

 

[pieter.oneill]

Sounds like you been getting out an about on the bike, I'd love to take some nice long road trips bit for now.i have to settle for my weekend blasts untill my son gets older he's 5 now but he's loving riding his little bikes. On a side note John gemi messaged me last night he's not sure why the chip didn't work straight after install so he's sending me another just incase something was up.will take 2 weeks to get here but will try again when it does

 

[Wrigsby1]

I have had several chip on different 1100gs with no probs but you should like it was well and truly flooded and my experience is once flooded they are a real PIA to start... Happens rarely but it may be it just needed time to clear a then a restart was as normal... I used to fill up with fuel near where I worked on one of mine and a start, hen stop, then start could make it a pig to restart... Simple as that and as long as the Gemi chip went in OK as per advice it should be fine enough...

Don’t get hung up or side tracked about resetting the TPS, the bike does it automatically as you ride it,

 

[pieter.oneill]

good to know wrigsby1 about the flooding i was surprized how much fuel came out the exhaust when it did not start over a couple of turn overs that's why my first thought was the chip had affected the fuelling ratio or caused something to interfere with something else, great thing is with these bikes is you can whip the plugs out in thirty seconds to dry off. Ill up date once i stick the JG chip back in and see how she goes.
