MY CAR IS HAVING TWO PROBLEMS REGARDING STARTING AND SECOND ONE IS RELATED TO ENGINE NOISE!

2001 Honda City • 96,000 miles

Hi there, hope you are good! Sir,
I have bought used Honda city 2001 auto transmission car here in Lahore, Pakistan! My car has a main problem since the day I got it, it freaks out when I start it in the cold state, it takes too long to start or frequently battery dies during the try however many times car just gets start for a sec n than off and vice versa, I have changed my fuel pump, checked my wiring by a technician installed new air cleaner assembly and not only that got my injectors cleaned as well! My car has a CNG installed in it as well so I got my whole CNG kit services as well just two months ago got a new battery as well in short I have spent more than 20000 bucks and still the problem is not solved!
And second issue is just two days ago I got a strange noise in my car's engine and when I got it checked from a mechanic he said the cars crank rings (be-guns)have failed one or two, might be the engine would be over hauled and than pistons would be repaired along-with other things!
But as far as engine is concerned my car is not depleting the Mobil oil and neither is its exhausting smoke (black or white)from silencer somehow near 7500 RPM car do puts some white smoke a Lil amount to exhaust system, now please tell me what to do!
thanks in advance ASAP =)

No sir I just got my oil changed a day before yesterday I use shell lubricant, the oil was full in reading it wasnt depleted at all though I think I have used it more than 3000 kms to 3500 kms but the technician said that oil was still in good condition, it had the elasticity portion! I use to focus on all of the oils n water before hitting the road!
I'm very much concerned about my car, I have maintained it well above my pocket but this thing is buggung me alot =(

Furtherly what are con rod bearings? Are they related with crank?

Those are the main bearings between the crank shaft and the connecting rods.

You can drop the oil pan and replace the bearings but if there are excessive wear on the crankshaft journals, you would have to replace the crankshaft or machine it to an oversize.

Hey Hope you are doing great! And once again I am facing an issue this time a lil bigger one though! I was in a rush to return back my home suddenly on the way back on road my car just stopped as in it got off due to low RPM and when I tried to start it it wasn't going onn! I checked battery water and oils all in this case all were okay! Even radiator wasn't making that pressure! Though battery seemed to went down a bit as car was taking load on self! Anyhows after 15 mins the car got started but was missing badly both on petrol and CNG on low RPM when engaged in a gear at D(auto transmission) Went to mechanic not far from there he checked it and diagnosed that my head's walls are weaken enough as smoke was coming out from the oil cover when he opened it! Can you guide me as your guidence really healped be before as well! Thanks in advance =)

I don't know what nonsense the mechanic was spouting about the head walls weakening.

Symptoms indicates you most probably hads a bad cylinder and it could be the piston rings or leaking valves, which is common for CNG engines as the valve sealts tends to wear quickly for this engine.

Have the compression tested to find out which cylinder is low on pressure.

Sir. Hope you are doing great. Now I got some transmission issue with my ride. I was driving my car suddenly it started giving whirling and grinding sounds and from gear box basically. Now that I was driving the gear was on D suddenly the car became neutral automatically I mean it stopped giving power to engine. I restart the car and put the gear to D it went great however this issue remained there and the gear is not shifting and not engaging so. I have changed the oil and throttle cables too but it dint effect much
Any advice mechanic says that the plates of gear needs to be redone how ever I am confused what to do.

What transmission do you have? Symptoms indicates the transmission either has internal faults or some control components are not working correctly. Check for trouble codes.
