Difficulty in starting engine.

[Luv_presea]

I have been experiencing difficulty in starting my engine for a few weeks now. the problem is not constant. sometimes start without a hint of problem, sometimes can't start.

 

The problem is when i crank the engine, it will either:

1) keep on cranking like there's no fuel supply,

2) have a choking feeling. like wanna start but can't, and can feel e engine jerking,

3) start but after a few secs, will jerk and then stall or

4) crank a few secs, jerk a bit, then start without a prob.

 

 

No difference whether i start the car:

1) when cold,

2) when warmed up,

3) in the day or at night,

4) after car parked for many hours or

5) immediately after shutting off the engine.

 

it is just random. as and when it likes.

 

Car is a Manual 07 lancer GLX 1.6

 

Brought to mechanic and still unable to rectify the problem.

mechanic checked fuel pump, fuel regulator, injector, ECU, battery, fuel pressure and all seemed to be running fine. Any ideas anyone?
