Might I suggest going about the diagnosis in a more systematic manner.



1. Check free , constant and adequate flow of fuel to the carb, both when the engine is cold and at operating temperature.

2. Clean out the carb, fuel tank,replace the fuel filter



3.Check all ignition connections including the ignition switch itself.Also the connections on the ammeter ( if your car has one)

4. Check high tension leads, ignition coil, contact breaker points, condensor, rotor, distributor cap for moisture and other issues.

5.Check battery terminals for sulphation

6. Check proper earthing on the car.



Hope this helps

So my 1986 Padmini about 2 weeks did a Mumbai to Surat run successfully. It didn't have any problems and drove perfectly fine and my mechanic was able to cover a distance of 300 kms within 7 -8 hours at roughly a speed of 60-80 that also in rain.

I drove the car in Surat for short spins of 2-3 kms in these 2 weeks but I used to start it everyday sometimes even twice and let it idle for a good 10-15 mins.

Last night the car refused to start, it took self but engine didn't turn over, I let it be after trying a few times.

In the morning I tried again but still it wouldn't turn over, I let it be again.

After an hour I tried to start it again, it started, I raced it a little, let it idle for 10-15 then I went for a 2-3 kms spin and came back and I raced it a little bit but the moment I left the accelerator it switched off on its own.

I spoke to my mechanic in Mumbai he told me to start the car after switching off the electric fuel pump that we have in the car, but it didn't start rather it started only with it being on auto.

Now the car doesn't even take self. So I have let it rest.

My mechanic told me it could be loose wiring on the ignition, or battery or fuel pump. I am wondering what the issue is ?

Hope somebody can help me out. Thanks .
What is complicating the understanding is your usage of the terms "Takes self" "doesn't turn over".

"Doesn't turn over" usually means the engine is not cranking/rotating at all
"takes self" usually indicates cranking

with this in mind, your definition means that you can hear the Starter engage, but nothing else happens. However you're also speaking about the "rhrhrhr sound from the engine"

Do you mean that it is "turning over but not starting up"?

If that is the case, how is the "turning over, speed". Does it start up each time you try with a better battery?

Doesn't turn over meaning you hear the starter engage and engine makes rhrrhr noise but it doesn't start. Right now after cleaning carb and installing new battery terminals it starts up quickly however due to rains I am not taking it out for a drive as I don't want it to catch rust as it is carefully parked under my shaded parking. The only thing I can do is start it and let it idle for 5-10 mins.

So when the problem started the car was cranking but the engine wasn't turning over, after 3-4 days we realised the battery was going flat so we pulled the battery cord and let it be. Due to this the car had a flat battery when we reconnected after a week. On reconnection with a new battery the engine immediately turned over like nothing had happened which was surprising. The mechanic took the battery and got it charged, then he tuned up the engine for slightly faster tuning as he felt the need for it. He said the point condenser needs to be rubbed with a carbon paper which he did.

Due to rains and parking issues I cannot take it out daily but I do make it a point to start it daily and let it idle for about 5-10 mins. After a week or so I took it out, car ran for 5 kms and then I returned and it went off again, engine didn't turn over again so I let it be for a few mins, after 5 mins it turned over and I reversed and parked it in its spot. After sometime took it out for another 2 kms spin and on the way it went off while at a U turn, had to push and jump start it in the 2nd gear, afterwards brought it back and tried to reverse but again it went off after which the engine didn't turn over again even after letting the engine cool off. Had to call the mechanic as we had to push the car into the parking spot, he came and said there was kachra in carburettor, he blew thru it and removed it and the engine turned over. Now have to fill up engine oil as it's showing low and take it out for a longer drive.

Longer drive keeps me worried as I prefer to do it in the wee hours in the morning or late at night so that the roads are empty but if it goes off then it's a headache to sort out.

Kindly advice.
I think this is a vapour lock issue. You need to get a electric fuel pump installed if not already. I think the petrol mix in the last year or so has changed because of which it vaporises at lower temperatures then before. It has been happening for me in all cars that ran very well a year ago but suddenly stall after some operating temperature is reached. What I did to check this issue was I poured a bottle of cold water on the mechanical fuel pump and the fuel line in the engine compartment and immediately the car started. Try this!

If an Electronic fuel pump is installed, pl. do not forget to put a "T" connector which returns one line back to the fuel tank. Drilling a new hole in the tank would be required.

Hi all.
In the year end vacation I was able to spend some time with my Padmini.
Fixed a few more door panel clips on the top side. Initially there were only 2. Padmini needs 4 per front door.

Installed a side mirror from Mahindra Jeeto, in place of the already installed Tata Nano side mirror. To install the Jeeto mirror, a small spacer about 3 mm thick was needed. Rest of the installation is straight forward

The window glass channel was fully rusted and needed replacement. But as you all know about the scarcity, I asked if the welder could prepare one with something he had in his collections. He thought for a while, pulled out a rectangular channel, with his grinding machine he made it into an U section.
Welded the rope mounts from old channel to the new. And it was ready in 20 minutes. I was fully impressed with his skills.

Default Plastic Fuel Tank

Fed up of rust in the tank made me think of alternate options. Thought of aluminium & stainless options. But finding a fabricator and getting one prepared at my home town is again a difficult task. Suddenly I remembered our neighbour's Tata Ace. Of course it had a steel tank. However got to know from a commercial vehicles dealer that Ace also came with plastic diesel tank on some models. And that was good news. Grabbed the part number, placed the order and it was ready for grabs. Price 2287/-.
After removing the old tank, tried fitting this plastic tank at the same place. The gap between the tank and spring leaf was too small. The tank was too close to tail pipe on the right side. The height of the Ace tank was more that the tank would hang too low posing a risk of getting damaged easily.
Plan B. Place the tank as in an Ambassador. Just behind the rear seat. Did some measurements to clear the spare wheel. But in this method the original filler neck stays below the new tank. Hence the filler neck went inside the boot. Here are some pics.

Great job, @ilangop.

Reminded me of an ORVM that I'd installed in my first car in 1998. The mirror was an aftermarket one and cost a mere 60 rupees.

Good thinking - this is how LPG and CNG aftermarket tanks are placed.

I have a suggestion - having gotten this far, and placed the tank like how it's done in the Ambassador, make the filler cap pucca.

Create a fuel filler lid on the left quarter panel a little higher than the tank inlet.

You can buy an old Maruti 800 filler lid, filler nozzle, with its mounting and weld the lid + mounting onto the left quarter panel, then connect the filling nozzle to the tank inlet using, say even the Tata Ace hose and clamps.
