Mahirap ma-determine w/o sound sample.

are you sure it is a buzzing sound like this?

or it's a rattling sound?

RE: Mirage won't start
Just experienced hard start this morning. May redondo but it feels like the engine is struggling. Thought it was a battery issue so I hooked up my jumpstarter powerbank. Same thing pa rin as if the engine is choking but I guess mas malakas yung cranking current ng jumpstarter so I got it running after 2 tries.

Mukha namang back to normal na pero baka umulit pag matagal napahinga ang kotse.

Ano kaya ang possible problem? Weekend driven ito. Last na gamit nito was 2 days ago when my wife moved the car slightly forward sa pagkaka--park. So mga ilang seconds lang umandar then patay agad makina. Could that be it?

I just opened the gas tank and released the pressure, I hope the problem doesn't recur. Worry ko fuel pump. If it'll fail, I hope it does while it's still within warranty.

- still my suspect >> the battery

I think it has considerably lost cranking power (undercharged). Kahit sukat mo w/ a voltmeter w/o load is 12.6V, when AH capacity has dropped, hirap i-crank 'yong engine.

Voltage actually dipped to 11.9 V on my first attempt that's why I thought it needed an extra boost from the powerbank. Now that I've used it for the past 2 days, the voltage is at 12.3 V when parked for an hour or so.

Sadly, I haven't got the budget yet to get anything better than Motolite.

RE: Mirage won't start
My car is going from 250KM/week-driven to a <25-50KM/week-driven that started 2nd week of this month. So, this is a scenario where my battery will lose SOC (state of charge).

BUT..

I have ...

a BM2 monitor to track condition of the battery (real time)

and ..

a 7-stage battery charger.

This is what I call preventive maintenance.

I had a change oil almost 2.5 years ago in motech, LP make sure bantayan mo when they are doing it because theyve poured a used oil. I noticed it after experiencing heavy gas pedal at cranky engine sound kahit bagong change oil. I availed of their
Liquimoly but learnt that it was a used oil kase sobrang itim nung chineck ko considering one week pa lang yung change oil at less than 10km lang tinakbo. When i empty the oil mas aobrang itim. I flushed it twice with mitsu ecooil. Bale 7 liters binili ko. After nuon ok na performance. Back to normal. Thats the reason i started DIY to my car.

Wow, matinding kalokohan yun ha. Kung sabihin man nilang naisalin ang used oil by mistake, I'm sure makikita nila ang kulay habang sinasalin nila.

Dun ko pa naman balak pa-change oil. I guess sa Customers Cradle na lang ako ulit.

RE: Mirage won't start
Aaaaaannnd... it happened again today. Inatras ko sha saglit kaninang morning. Tapos ngayung aalis na ako.. ayaw mag start. I did the instruction of pumping the accelerator, opening the gas tank (may pressure na narelease nung una kong pag open) ... and the cycle... so over time, umokey naman sha...


Naalala ko explanation nung SA ko dati. Nalulunod si mirage because of yung cylinders niya. Unlike yujg normal na sedan na may plus 1 cylinder. So the moment you start, nag pupump na agad ng gas... tapos dahil saglit ko lang siya nirun tapos patay ulit.. hindi nag run ng ayos ***hahah now that i think avout it medyo kulang na details ko***

So ang advice sakin nung SA kapag ganung isstart ko tapos andar konti.. wag ko agad patay ... let it run muna for few minutes more...

Mali ang SA mo sa explanation nya, hindi dahil 3 cylinder lang ang engine kaya nalulunod, walang issue kung ilan cylinders kung bakit nalulunod. Maraming pwede dahilan, maybe leaky injectors or ignition related issue mas plausible pa.

Pressure sa gas tank normal lang pagbukas ng gas cap, may purge system ang mirage to handle excess pressure.

May nabasa ako dati yung mga unang batches ng mirage may issue sa ECU regarding this, na pag off ng engine continuous ang pagspray ng injectors kaya pagstart lunod. Need lang ireprogram ang ECU sa casa based sa service bulletin.
