So is it cranking now ?
Also Check the starter relay and its connections.

Fuel pump was not making any whirling noise because after a preset time,the ecu cuts off the power supply to pump if the engine is not attempted to start.
Turn off the ignition and then turn on the ignition(do not start),you will see that the pump makes that whirling noise only for a few seconds.

Yes, the bike is absolutely normal now.

Never knew this cut off funda. Thanks.

No sound even after pressing the starter means its the relay. Am pretty sure. The same damn thing had happened to me. Had to push start the bike for few days! Even after pressing the self start, there would be no sound of cranking..just deadly silence!!!

Divya Sharan, the fact that even the push start didn't wake up the engine points to either a spark or fuel problem...spark problem will not let your bike start ever, so I presume it is the fuel pump getting hot and jamming and not giving the pressure needed to the injector......Since you confirmed on Phone that the Fuel pump area is also getting hot, I suggested you to wait for 10~15 minutes to cool it down ...and it so happens that the bike did start after that period of time....
The fuel pump is a DC motor, and contains carbon brushes just like the starter motor, and if it wears out the contact becomes poor, develops loose contact and heat, which further compounds the problem.....This seem to be a common problem with ZMR...if left as it is, after some time the fuel pump will fail totally and you will be stranded

There is also a chance that the fuse supplying the power to the Fuel pump had developed loose contact...

Sir,but I don't understand how starter not working and fuel pump are related .

@ Divya

Did you mean to say that the engine was turning over when the self button was pushed but it refused to start
OR
Even after repeated cranking by self start,the bike refused to start ?
Please be little clear,I am confused.

How much petrol was there in the tank ?

I'd approx 4-5 liters of fuel at the time. Moreover, for the engine to turn over, I must hear a click on thumbing the starter, but it was silent. No sound at all. It was like pressing the starter with ignition off. I hope I'm clear now.

If there was silence when you pushed the starter then it is the relay. But the bike started when pushed in my case. But in yours, the bike refused to start even when pushed? Meaning something other than starter relay.

Need some insights people. Giving my bike to SVC today. But Shoeb's post has put me in a doubt.

I stopped my bike for attending a call. Switched off the ignition and attended the call. (I don't really recall if I switched the keys back to ignition on state or not while talking on phone, I was sitting on the bike while talking on phone). The bike didn't start thereafter (now the key was in ON position, but unable to recall whether I put it in ON position during the call or later). I talked for nearly 130 sec BTW.

Now, I tried my antics. Switched off the ignition, opened the fuel cap; let air in for 5 odd sec. Switched back the ignition on. No crank. Battery was ok, headlights and horn worked. Attempted push start. Failed.

Called a few people until I could connect to psr sir.

But after a failed push start, I never switched off the ignition again and pushed for 20-25 mins or so. Finally, reached a bakery to have some water. Switched off the ignition, locked the bike and returned after 2 min. Switched on and voila! Bike started.

For better comprehending Shoeb's ECU funda, I've highlighted the parts in bold. Can someone help me understand if the ECU had cut off the fuel supply?

Check the bank angle sensor, may be it is faulty and cutting up power supply to the ECU. My friends ZMR had same problem which would occasionally pop up until one day i caught the problem.
May be problem with ECU, but hardly ECU gives fault, check the bank angle sensor.

Divya, I am not sure if your issue was ECU-specific, but I had encountered this problem couple of times on my previous bike (Yamaha Gladiator) and even a couple of times on my CBR. I have never been able to pinpoint the exact cause, though I feel the culprit was the engine-kill switch in all the cases. Here's what happened with the Gladiator:

Starts normally when I leave from home, I ride for 5+ kms.
I stop at some traffic signal, use the engine kill switch to turn off the engine.
I turn on the killswitch and crank the bike.
Bike doesn't crank.
I turn off ignition and turn on again, check for fuel, check indicators and horn, all work.
I tried the kickstart, it still didn't start.
Used the choke and tried KS, still no go.
Finally here's what solved the issue:
I flicked the engine kill switch some 5-6 times, then switched off the ignition, and turned it back on. Crank the ignition and bike starts with a purr, as if nothing ever happened.

Went through this issue couple of times, and finally got to know the workaround, and I suspect It was due to some deposit/carbon build up inside the killswitch or probably some failed contact. Recently, I encountered the same situation twice on my CBR, and the very same trick bailed me out.

HOWEVER...the zimmer doesn't have an engine-kill switch! So, I can attribute the problem to some other electrical component. The bank-sensor and ECU options can not be entirely ruled out, but there could be a simpler solution...do get the electricals checked.

Guys.. Does anyone here have the wiring diagram of the ZMR?? Please upload it if you guys have it.. want to diagnose the battery draining issue.. Thanks in advance guys..

@divya.. i am assuming its some issue with the wiring as I used to face the same issue on my Karizma few years back.. get the wiring completely checked..

@Divya bro,

Rum..Pum..Pum..Pum... Vacuum/Electronic operated fuel tap....

Oh, Sorry, was just thinking out loud.

Sibun,Please don't take me wrong but see this.

Here is my opinion on self-starter not responding at all.

Suppose the Bank angle sensor goes kaput then all the parts which are dependent on ECU stop working( injector, Fuel Pump, ignition Coil all stop working)

BUT, The signal to the starter relay is no-where related to the ECU so the starter must have worked even if the bank angle sensor goes kaput or even if the fuel pump,injector,ecu also goes kaput.
As the self-start's circuit is totally independent of the ECU and the signal it receives from various parts.

Started relay depends upon the
1. Clutch switch/Neutral signal.
2. Whether it is getting current from the starter button.
3. Whether the fuse was OK.
4.The relay got stuck momentarily. Highly possible.

If the electric starter had worked but the engine refused to start then we could have blamed ECU/ injector/ Fuel Pump/ ignition Coil/Bank angle sensor for fault. But after taking the call,the engine did not even turn over even once.Hence my reason for blaming the starting circuit/ the starter relay.

Now what actually confuses me is that the bike refused to start even after push starting but it started after resetting the ignition switch after some time. This points to the bank angle sensor as once the bank angle sensor is activated,it gets latched. In your case it might have stuck then re-setting the ignition switch multiple times set it free.

Was the bike having enough momentum to push start ? If yes then :-

It could be due to two combined problems 1.Starter circuit/starter relay and 2.Bank angle sensor getting stuck "somehow".

I am not offending you dear Sibun,just expressing my opinion. I am no expert and can be wrong. Will be thankful to get corrected.

My Experience with these tires were bad.. the front tire seems pretty ok.. but the rear ones skid a lot during heavy downpour.. I had to take my legs off the pedal everytime i applied brake to balance myself..


I am using it as a Tubeless and its not that great.. Gonna go for the PSD next month after the salary is credited.. else the month after that will use the Michelin Sirac for the RX135


same experience.. to avoid the 360 turns.. I had to balance with my legs.. risky though.. i was not confident during turns..

I am using it Tubeless & there is no problem while using it Tubeless..though once my rim had a slight bent so air was leaking from it(just slightly)..but that can happen to any tubeless tire..no bad experience in terms of gripping or durability!!
