People s 125 won’t start.

[Terryvanman]

Hi guys me again. My mate has a People’s S125. It’s 5 years old with just 5000 kilomètres on the clock one owner from new. It has stood for over a year so he had it serviced with new pads battery and all the usual new filters and oils. I collected it from the mechanic and it started first time and covered the 2 kilomètres home with no trouble
Next morning it won’t start, the new battery had tons of charge and the engine turns over, on inspecting the new spark plug that too had a nice bright spark. We Thought that maybe it was out of fuel as the gage might be stuck on a quarter of a tank, put in some fresh fuel and the needle didn’t move but a gallon went in. We made sure the stand was up and no problem with any kill switch as there ain’t one
So has anyone had the same problem,if so what was it?

With key on, is the brake light lit when you pull the brake lever?

Hi Tom, I’ll check in the morning Malta time

Since the People S 125 is an injector model already, I would go for a blocked injector nozzle by gunk.

Spark is there, fuel in tank....
-battery completely full or jump cables on

Listen whether the fuelpump works for a few seconds when you switch ignition on.

-take off fuel hose from injector
-put hose in a jar or similar
-ignition on
Fuel YES/NO (really fuel or water?)
IF YES

-injector out, connect with fuelhose  again
-jar under nozzle
-ignition on
-starter button
SPRAYS FINE OUT OF NOZZLE?

OK, no sound of fuel pump working when turned on, petrol getting to the injector but just as trickle when come out of injector when turned over. So I’m thinking the fuel filter could be blocked the pump is faulty/blocked or the injector is blocked

Well, no pumpsound:
- check fuses (renew)
- check/interchange fuelpump relay under front
- check cables towards fuelpump
- follow fuel line for interuptions
- take any additional fuel filter out of the line (your pump has a filter already)

All fine?

- fuelpump out and benchtest
- sound? Yes/No

- fuelpump should have a pressure of 3 bar minimum

Injector: returnflush with fuel or alcohol/diesel

Pulled the fuel line off the injector and pressed the starter and no fuel came out this time not even a trickle, so probably a blocked filter or DUFF pump….first I’ll check the fuses, anyone know what fuse is for the fuel pump, where is the fuel pump relay, what does it look like please?

For relays pls see pics, located in your scoots front, fairing with headlight has to be removed.

Pump: multimeter on cables for pump
-ignition on
-12+V should be there

Fuses: multimeter still on cables,  shows current, take fuse one by one out, current off this fuse is it

Thanks everyone for all your help….being a non mechanic I’m waving the white flag and taking it to a local ( professional) mechanic. It was fun having a go.

Don’t forget to let us know what it was when you find out?  It all adds to the sum of knowledge on here!
