Hard starting problem: Help me diagnose my car

**cocoy_01** · July 7th, 2007 10:20 PM

Hello guys, i have a problem with my car. Its a carby, contact point type car.

Lately, i experience hard starting when the car has just been parked for half an hour, when it was just turned off or overnight(kahit kelan hard start na). The engine cranks and all, pero ayaw tumuloy ng start. Even apakan mo accelerator to help the engine start, walang kwenta. I know this is not normal, kasi dati one-try lang okay na.

I also encounter yung parang pumupugak pugak yung oto, even at normal speeds(40kph) or if ihahataw ko.

Carb newly overhauled by A & M
Fuel filter good
Battery good (checked)
Alternator good (checked 14v on idle, 13.8v acc all on)
Timing set already
New contact points/condenser (genuine)
Plugs cleaned
Valve clearance adjusted

Possible problem?
Timing
ignition coil
carb
fuel pump
etc..

please help me, daily driven pa naman ang oto, yari pag tumirik.

what about high tension wires? di kaya tumatalon kuryente? hth

i haven't really checked on that. the engine responds naman when you remove hitension wires from teh plugs.

Bro, try mo ulit check yung battery mo. kung 2+ yrs old na, palitan mo na. Also make sure na mahigpit yung mga terminals. Sana makatulong.

i had the battery checked by a battery shop store. Battery is okay daw. Malakas naman ang crank ng engine. I can say that, kasi nung bumigay yung alternator ng isang oto, nadiskarga ang battery, yun talagang halos di na umikot ang starter.

bro, kung ayaw mag-start, paano mo pinapaandar ulit? wait na lang tayo ng iba pang sugestions.

have you checked your starter?

**cocoy_01** · July 8th, 2007 12:04 PM

i havent checked on my started... diba pag defective starter, di man lang mag rotate ito or redondo? if defective, clicking sound lang maririnig right?

Won't hurt to have it checked.

same prob... engine cranks but doesn't start.. wala spark.. kaya di ko magamit ngayon ( i even started a thread on that), likewise, pupugak pugak din minsan.. but mine's A/T (97 Mazda familia 323). I might have it rewired or checked for loose connections.. yun nga lang singil nung mekaniko / electrician P3k.. Ewan kung reasonable yung presyo with 6 months warranty naman.

What could be the problem pag pupugak pugak?
