Jake :

Good day.

Jake :

what year is your micra

Jake :

03 ?

JACUSTOMER-5yaj3phr- : I'm sorry not sure of exact year.i didn't purchase form new.I thought about 6 yrs old
Jake :

that's ok. Did you replace the pump yourself?

JACUSTOMER-5yaj3phr- : No a garage.
Jake :

ok good, just wanted to make sure the SCV was calibrated properly.

Jake :

what happens when you try to start the vehicle?

JACUSTOMER-5yaj3phr- : The red engine warning light comes on.and have to keep revving
Jake :

So the engine will start ok, but for it to continue running you need to give it gas?

Jake :

is that correct?

JACUSTOMER-5yaj3phr- : It takes several times with foot on gas. Before it will start.if the red engine light remains on after I have got it started.i have to stop and start again.
Jake :

are you talking about the immobiliser light or the service engine light?

JACUSTOMER-5yaj3phr- : The engine light.
Jake :

have you seen what fault is stored?

JACUSTOMER-5yaj3phr- : No
JACUSTOMER-5yaj3phr- : It just shows a red engine light
Jake :

well the engine code would certainly help

Jake :

because pumping the gas could indicate an issue with flooding

Jake :

or the throttle itself.

JACUSTOMER-5yaj3phr- : It just shows a picture no actual code is shownn
Jake :

I'm sorry, this chat box is all messed up

Jake :

i had been typing and noticed it said "disconnected" on the left and side

Jake :

when i refreshed it nothing i typed was actually going through

Jake :

the code is somethign that has to be retrieved with a scan tool

Jake :

so if the garage didn't pull the code you wouldn't have that info i understand.

Jake :

something that's pretty common on these cars is crank sensor failure.

Jake :

the crank sensor reads the rpm signal

Jake :

which the pump uses to operate.

Jake :

if your certain it;s a fuel issue this would certainly be a good place to start

Jake :

but the pumping of the gas pedal at start up, usually indicates either a throttle issue, or flooding condition that is rectified by letting more air in to clear the cylinders

Jake :

so since you just fitted a new filter, make sure there is no air in the fuel lines first, then address the things i mentioned.

Jake :

if you run into further questions just ask

Jake :

thanks
