ok guys...my car is running on factory fitted fuel pump...never opened...it had been hesitating on pick up....had my suspicion on pump...but went for pressure check....found 70 bars after fuel filter...seems okay....checked injectors....seems clogged...cud not find ultrasonic cleaner nearby....used desi method...applying pressure thru carb cleaner and pulsing injectors one by one...worked out pretty nicely....car is back to life Alhamdolillah...
so never listen to ustaads etc....follow ur own instinct and have faith in Allah....
secret behind long life of fuel pump: always keep tank half full...never add any octane booster or injector cleaner in pump...
story behind injector clogging.....car is parked most of times....sometimes months in a stretch...so better keep it running regularly...
hell of a tough car...Alhamdolillah...never breaks down...
