Starting hiccups

Question : I WONDER whether it is normal for fuel injection cars to have starting hiccups when cranking on the first time, i.e. cranking sound is there but the engine does not start.

If it is not normal, then what could be the cause? How to rectify it ?

My workshop has not been able to solve the problem after many trials and errors.

Answer : Two things need to happen to start an engine:

1. There must be sufficient fuel pressure to the injectors, and

2. When the engine is cold, the cold start valve to activate it in order that there is a richer fuel mixture to start.

If the pressure is insufficient, there will be difficulty starting. If you have to crank for a long time to start the engine even when the engine is hot, then also look at the ignition timing.

My frank opinion is that the service shop that you are going to does not have sufficiently trained technicians and you should go to a bigger set-up with better facilities.
