Pointy no spark
 

I am rebuilding an 05 pointy. It was running fine but now it wont start at all.
The battery is good and it turns over well
F1 is showing on the dash. I have done a search & found the diag link & used my home made "diag tool" it says c-00 which is normal & the TPS is set correctly, no further codes have shown up.
So back to basics, there is no spark at either plug and although I can hear the fuel pump the plugs are dry.
The side stand switch has been in and out since I changed the plugs but if that was playing up wouldn't it stop it spinning over?
Any idea what to check next?
Thanks

Re: Pointy no spark
 

you really need to download the manual as it explains all about FI problem diagnosis. One important thing is that each time the ignition is turned off the fault code memory is wiped so you need to put it into dealer mode and then try a start.....

Re: Pointy no spark
 

stop/run switchgear switch. you need to check the continuity of the switch in/out. IIR you can do it at the switchgear end instead of the connector end (which is a nightmare to get off)

Re: Pointy no spark
 

So would it still turn over if the switchgear was playing up?

Re: Pointy no spark
 

Yeah done that, no new, additional codes came up

Re: Pointy no spark
 

Can you give me an idiots guide how to check the continuity please, Ive got a multimeter

Re: Pointy no spark
 

its pretty simple. this is very very basic testing. you can do the same with a simple bulb tester rig.

stick the red DMM probe on/in the OUT wire (Orange/White) of the switch. turn your DMM to 20vdc and turn the bike on then put the stop/run switch to ON then place the black probe of the DMM to the frame or negative battery terminal if there is no voltage when the switch is ON then the switch is fubar.

to check you are getting power into the switch do the same as above but use the Orange/Black wire.

if you cant get at any terminals or solder blobs then stick probes through the insulation of the wire. once done put a blob of glue in the hole. or use a hot needle to melt/scrape a little insulation over the hole.

Re: Pointy no spark
 

hhmmm come to think about it the bike wont even turn over if the switch is fubar.

have you checked the fuses?

do you have an alarm fitted?

Re: Pointy no spark
 

Yep checked the fuses, no alarm fitted

Re: Pointy no spark
 

check the Orange/White wire terminal on the connector loom of the stop/start switchgear.

have you had the ECU out at any point?

Re: Pointy no spark
 

Thanks, i will check that, yes the ECU has been out but it has been running since I put it back in

Re: Pointy no spark
 

all i can think of is that you haven't plugged something in. check the STVA connector is plugged in.

if it was running then not think of the last thing you done.

safety switches on the pointy will stop the bike from actually turning over.

if the plugs are dry then its not getting fuel.

Re: Pointy no spark
 

there is no resistor built into pointy switch. i've had one apart.

Re: Pointy no spark
 

nope never missed it there is none on UK pointys.

some of the US ones have them apparently.

Re: Pointy no spark
 

""check the STVA connector is plugged in"" where is that? I had the air box off is it part of that?

I realised that it is not getting fuel, but no spark as well, what could be a common fault?

Re: Pointy no spark
 

I cant see it being any sensors or anything on this list as the appropriate code would show up so I can only think its a problem with the ECU or its connections.......

C12 Crankshaft position sensor (CKPS) Pick-up coil signal, signal generator C13 Intake air position sensor (ZAPS) C14 Throttle position sensor (TPS) C15 Engine coolant temperature sensor (ECTS) C21 Intake air temperature sensor (IATS) C23 Tip over sensor (TOS) C24 Ignition signal #1 (IG coil #1) For #1 cylinder C25 Ignition signal #2 (IG coil #2) For #2 cylinder C28 Secondary throttle valve actuator (STVA) C29 Secondary throttle position sensor (STPS) C31 Gear position signal (GP switch) C32 Fuel injector signal #1 For #1 cylinder C33 Fuel injector signal #2 For #2 cylinder C41 Fuel pump control system (FP control system) Fuel pump relay C42 Ignition switch signal (IG switch signal) Anti-theft C49 PAIR control solenoid valve

Re: Pointy no spark
 

STVA is under the airbox at the front RHS (sitting on bike) of the frame. the connectors on the airbox including the rubber hoses will throw an FI but wont stop the bike from running but disconnecting the STVA will.

Re: Pointy no spark
 

Thanks very much, I wont get the chance to look at it until next weekend but will let you know the outcome

Re: Pointy no spark
 

OK thanks, I will double check the connections

Re: Pointy no spark
 

Checked the SVTA and thats plugged in ok, checked the ECU is plugged in ok.Had the starter switch apart & checked the orange & white wires, checked the fuses,changed the starter solenoid. Took the side stand switch off and checked the connection. Still no spark, the pump is priming but the plugs are not getting wet, Ive not disconnected the fuelhose to see if fuel is coming through as I broke the clip on the connector once before and I dont want to do it again. Put it into dealer mode again & still no additional codes. Looks like I am going to have to take it to my local friendly Suzuki dealer unless anybody else has any ideas?

Re: Pointy no spark
 

Does the FI light come up as soon as you turn on the ignition or only when you try a start? And the procedure youre using for code testing is definitely: ignition off, put dealer mode wire into connector block, turn ignition on, try start and look for code?
The only suggestion Ive got isnt nice but could the ECU be knackered? You can either try to swop it with a very good friend's unit or go to your dealer.......

Re: Pointy no spark
 

Yes the FI light comes on when I turn the ignition on & the procedure is exactly as you said. I was beginning to come to the same conclusion as you about the ECU, i will see if i can pick up a cheap one on Ebay as a last resort before sending it to the dealer.
Thanks

Re: Pointy no spark
 

Picked up an other ecu locally, still the same!!!!!!!!!!!!!!
Trying to make a choice now, dealer or bonfire

Re: Pointy no spark
 

just to recap what you have:
water temperature reading has gone and in its place 'FI' letters indicated continuously,
to the left of the speed reading 'FI' letters indicated and blinks,
red oil pressure/FI light on and blinks.

Re: Pointy no spark
 

FI comes on solid with the ignition on, no blinking, FI light goes when I hit the starter button

Re: Pointy no spark
 

Not done any of that, its getting into areas I dont have any experience of

Re: Pointy no spark
 

And do you get the two lots of 'FI' letters or not? If not then its not indicating an FI fault but oil pressure and is correctly going out when the motor turns over and pressure builds up.....

Re: Pointy no spark
 

Only 1 FI not 2 so does that mean that I have been "barking up the wrong tree"

Re: Pointy no spark
 

so where are the letters 'FI' showing, below the speed reading where engine temperature normally shows or to the left of it?

Re: Pointy no spark
 

Unfortunately everybody calls the red warning light the FI light but it can also indicate a high coolant temperature and low oil pressure.....

Re: Pointy no spark
 

Thanks for everybodys input and help, its a bit like buying a kitchen, the more you look at it the more options there are. I am going to get the dealer to have a look at it, I used them before with a GSF650 and they were sensible.
I will update this thread with the fix to broaden the general knowldge and hopefullly help somebody else in the future.

Re: Pointy no spark
 

To the left

Re: Pointy no spark
 

youre probably right but I cant understand what Stilo has found different this time when starting the bike as the red light must have come on every time the ignition has been turned on since owning the bike and then gone out when cranking - whats different this time to indicate an FI problem or is it just because it didnt start?

Re: Pointy no spark
 

ok Stilo we crossed. Well if theres no other indications then the problem doesnt match anything in the manual so Im afraid its got to be the dealer.....

Re: Pointy no spark
 

When I turn the ignition on the FI light is only on for a few seconds on the left of the dash as you look at it, it goes off before I hit the starter button. The dash remains the same without the FI light befor and after I have hit the starter button

Re: Pointy no spark
 

well the plot thickens then cos when I turn my ignition on the red light illuminates and stays on until I get oil pressure during cranking/firing. Once running it will only come back on for oil pressure failure, overheating or an FI problem (along with the other 'FI' letters)

Re: Pointy no spark
 

The dealer cant get me in for a couple of weeks so here's a recap to see if there any more thoughts:
No start: pulled the plugs,no spark on either of them, tried 2 sets of plugs,just the same.
The dash lights up correctly, FI comes on when I turn on the ignition then goes out after a couple of seconds.
Put it in "dealer mode" and turned it over,no codes show up which says that the injection system is OK and all of the safety systems, side stand switch, tip over etc are OK?
Checked the wires in the starter switch, tried another starter switch.
Pulled apart & checked all of the connections on the throttle bodies
Tried another ECU
Disconnected the fuel line and fuel is coming through.
So all of this says to me, the fuel and injection system is ok but nothing is getting to or out of the coils?
I have a multimeter but I am not up to speed with checking circuits etc, how, idiots guide please, do I check the current getting into & out of the coils, what else can I check?
Thanks

Re: Pointy no spark
 

Thats great thanks, I will give it a go in the morning

Re: Pointy no spark
 

Ive got power to both of the coils but I am struggling to find the orange wire with red stripe. I have an orange wire with a green band around it & looking at the wiring diagram thats the only orange wire I can find, could it be this?

Re: Pointy no spark
 

Battery measures 12.8v both coils 11.8v
