Liana eminent warm engine starting problem

[borgfilez]

i have a liana 1600 auto which starts with half self when engine is cold, but after driving 30 mins it requires multiple tries and after long drive sometimes requires a pump (accelerate pedal).
needle remains on half and it never goes past 3 or 4 tries.
when starting via pump i can smell petrol..
no CNG in car.

May be your fuel pump gone bad.

[borgfilez]

well problem symptoms I'm having doesn't go with bad fuel pump.

[moeez4942]

It seems like the wiring for the starter is bad somewhere.

[borgfilez]

and that will make starting problem when warm?
will try to check this.

while searching same many comments on internet is about leaking injections... will test them too.

[Bilalicious]

Seems like fuel pump needs replacement. Can you confirm since how long you have been using the battery?

[borgfilez]

battery is 3weeks old and its of recommended amps.
fuel pump and filter was cleaned 3 days back and no fault was found in pump.

pls remember cold engine starts in half self.
avg is between 8 to 10 with ac.

Take it for a drive in preferably no-noise area, listen carefully of some sound (a humming sound) is coming from back. Of you do hear any such sound, the fuel pump is gone. Replace the clogged fuel filter as well when you change the fuel pump.

Also check the wiring harness for starter

[borgfilez]

fuel pump would be last thing ill change if problem persisted.
as I've already stated above, all got checked out fine.

here's what I've planned for in next few days.... and by this preference and wiil update here.

have ect sensor check
have fuel injectors check
have starter harness and or starter check (as mentioned here)

if all fails ill go for fuel pump replacement. how much a pump cost?

[ahmedstudio]

Don't remove the fuel pump. I suggested for an audible check.
As a first step here's what you can do.
After 30 minutes of drive when it starts giving you trouble in starting, remove the fuel cap from the gas tank and hear for pressure release. If fuel tank vent is plugged up so much that pressure is building up in the fuel lines, this problem can happen.

It could also be leaky injectors. On cold engine the additonal fuel doesn't make any difference in starting but when engine is hot, the trickling drops of fuel get vaporized on the piston crown, and then it back fills through the inlet manifold into the air filter.

It could also be faulty ignition coil breaking down whne engine reaches operating temperature.

[borgfilez]

• fuel pump was checked no audible sound. filter was cleaned (it was too dirty) tank was cleaned and fuel pump was checked. (manually) for enough flow*

yes ill check all these points tomorrow
so if i hear pressure release... what next?

oh ignition coil.... i think i have one that is repaired before and mechanic told me this is not good practice but he too forget i think. i just remembered.

[ahmedstudio]

If you hear pressure realise then you'll have to get the fuel lines insulated

[borgfilez]

oh ignition coil.... i think i have one that is repaired before and mechanic told me this is not good practice but he too forget i think. i just remembered.

[ahmedstudio]

Then replace the faulty ignition coil breaking up on hot engine. It should resolve the issue. By the way, is engine check light showing up?

[borgfilez]

just to be confirmed
it is what i think.... when you remove engine cover its the cords connecting plugs?
one which was shorter in size was repaired.

[ahmedstudio]

Yes those are ignition coils.
Check condition of all.

[borgfilez]

off topic

do you know what sensor shows the temperature next to the clock which is on top of the dashboard. mine just display - -

[ahmedstudio]

That's ambient sensor showing the outside temperature

[borgfilez]

by any chance you know where to find it? so i can check it.

[dani_kk]

While trying to crank it, it refuses to spin starter? Or starter keeps on spinning easily?
Tell me if starter doesn't spins and produces tak tak sound
