Starting issues on my Suzuki Gixxer SF150: Faulty fuel pump says ASC

was about to leave work to visit the service center and there it is again, the engine won't ignite.

BHPian Mr.Bentley recently shared this with other enthusiasts.

New issue with my 2021 Gixxer SF 150 - engine refusing to start.

I got it serviced on June 6th, filled the tank at an IndianOil petrol bunk near my home. Rode about 60km since then without any problems.

June 8th:

9PM, after dinner at a restaurant; engine wont start. Self start seems to be working as it should. Starter motor is cranking the engine, but there is no ignition. (I can see its cranking to 500rpm). Jump start didn't work either. RSA quoted Rs.1800 to transport the bike for 6km on a flatbed. Local mechanics said they cant assure anything since they're not skilled enough to troubleshoot BS6 bikes. In the mean time, the valet at the restaurant (claimed that he used to be a bike mechanic himself) fiddled with the spark plug ignitor, and 2 mins later, the bike cranked! He said it was 'loose'.

Thankfully, an uneventful ride to home. I switched off the engine and tried cranking it again, and the engine is ON. Even next day, engine ignited at the first crank!

Continued riding it daily since I'm packed at work till June 16th, and can take it to service center only after that. So, rode only from Home to Work, since I can park the bike at either of them in case I face the issue again.

June 16th:

I was about to leave work to visit the service center and there it is again, the engine won't ignite! Same scene as above. I tried the spark plugs thing. That didn't work this time. Called up service center and asked to send someone to check this out. They said they will send only next day, since its already 5 30pm. Left it at office and went home. Visited the bike again on Saturday with a strong will to solve this. No drama today, the engine started on first crank!

Left it there and worked in office to finish off few things.

June 19th:

Took the bike to service center. After explaining all the above, the mechanic immediately alleged a faulty fuel pump in the bike. He said this issue has been common in Suzuki vehicles these days, and even replicated the problem! (revved the engine till about 8k rpm, and the engine shut down itself immediately and didn't start immediately again. It started 10mins later, on a random crank.

Fuel pump, if identified as the cause of issue, will be replaced under warranty (just 40days of warranty period left).

When talked around the service center, I got 3 types of statements:

• Service center manager also has a 2021 Gixxer 150. After knowing the issue, he guessed the age of the bike almost accurately. He claimed that he faced exact same issue at just 80km ODO. He got the fuel pump replaced, and all is well since then.
• Mechanic says this issue has been popping up in many Suzukis and the manufacturer is covering the 'first' fuel pump replacement under warranty (irrespective of age of vehicle).
• SA said he observed this issue in many vehicles, but never on those vehicles with E20 sticker on them. I asked him if the extra ethanol in fuel could cause this problem, but he seemed unaware of even what E20 means.

(And frankly, I don't know if the fuel I filled is E20 or not. Usually I fill XP95 every time. But this time, that particular dispenser is not working. So I filled normal petrol).

Don't know if this may be because of E20 fuel or not.
