does it crank when hot? crank but doesnt start? or crank, about to start but doesnt?

 

[karhong]

it does crank...but doesnt start nomatter how long i hold the key...so i need to close and pull the key out and try again for few times only to get start...after start,engine is like not stable...rpm oso wan drop like that...so i press oil to make rpm go up and only it stable at 1k rpm...

check plug white colour or brownish??


if white probably setting was lean...maybe fuel pump weak already?

or try adjusting ignition (via distributors or ecu)

i think ur starter need to "recarbon" or add some relay on it...

 

[karhong]

distributor,plug cable and spark plug is new 1...is it possible that injector head is dirty?

this thing is actually happens to me...i'm using civic 2005....in the morning can start easily...but after go shopping or yamca for a few minutes in the afternoon or even wanna stop for refueling....car cannot start...damn!!!....check to the mech and add some relay..it helps only for few days...problem still persist...last2 i check my battery...its 2008..hahaha...bought new battery and its all SETTLED!!!...maybe this problem vary for different cars...but y not check your battery first....

Starter too hot also can cause this problem my car also also same problem as you. When I go to pump petrol off the engine when want to start the cranking like battery want to dead after a while the 1 crank then start.

sounds like starter has weaken jer..

 

[karhong]

battery i changed last year dec...haiz...mech should be able to check right?

overheated fuel pump also makes the car hard to start....

the culprit is the main relay.

hope it helps.

for battery check, when u cranking...the starter cranking power strong or weak? strong = battery ok, weak = battery weak.

for fuel pump, some mech connect a fuel press meter at ur fuel line to check the pressure.

and make sure ur car petrol not always at 'E' level coz fuel pump easily get overheated when fuel level getting low in fuel tank... :)
