Cold/Stalling EU-I or Mpfi's
There’s already an Article on Cold/Stalling ‘EU-I’
Cars on our Sites under the following URL, which you may Surf for further

On the otherhand, with Mpfi’s, the picture is somewhat different.
The following are the possibilities - assuming that the Car has been serviced
in line with the OEM Stipulations :
i) That one is not allowing enough time for the fuel-pump to 'prime'
the System to the desired pressure – around 3 kg/cm - as evidenced
by an audible 'click' sound in the Cabin of the FP going off after a few
secs of turning on the Ignition.ii) That one’s giving too short a Crank. The first one in the mornings
has to be relatively a little longer than the ones during rest of the
day.iii) That one’s unknowingly stepping on the Accelerator Pedal -
even partially - which one is not supposed to for Mpfi's.iv) Faulty Coolant Temp and Air Intake Sensors/their Couplers - usually
the latter for a Car not too old. v) Worn out or larger than recommended Sparkplug Gaps.
vi) Clogged Fuel-Injectors - using a good Petrol Additive regularly like
a daily Vitamin Pill is a must with our regular/unleaded Petrol. And if
planning to switch over to the pre-detergent mixed fuels now available,
make sure one starts with a full tank with them. Otherwise, one runs the
risk of losing one’s Fuel Pump due to the high concentration of
dislodged gums and glues finding their way back into the Tank and thus
clogging the in-tank fuel pump’s intake filter and this killing
it !
