    Hi,
    I have a Punto 1.3 mjd emotion, which start giving trouble since last 4 month's.
    At present the problem is - Check Engine light is not comming in the dashboard for the fractional second, and more than 30 scanner guy confirmed that unless that tight comes for a fraction of second, scanner will not be able to even detect my car.

    I being not from automobile engineering found no solutions for that.

    Any advice is highly appreciated.

    Regards....

    What exactly is your problem?
    You are getting Check engine light, but it is not shown in scanning??
    Did you try scanning at FASS??

    Hi,

    I don't have any issue if CEL comes or not, but as far as the 'Automobile Engineer' concerned, they know only one thing, scan the car, scanner will detect the malfunctioning part, replace it. But yes, exception does have.

    Now since last 4 months I am running nook and cranny of kolkata to identify starting trouble. Did everything whatever said by whoever. Called FASs and asked for appt but it seemed they are not at all interested.

    Problem sorted yesterday, an automobile engineer, aged more than 70 years, meticulously checked every connection and found 2 relays are creating a short circuit. Including 2 relays he charged 400/- and out of genuine respect i paid him 500.


    Now back to basic, tomorrow I will get delivery of my own scanner, but unless CEL glows for fraction of sec, even my scanner won't be able to detect the car...

    Would you share more information about this? What were the symptoms? Were they consistent or occassional?
    How old is your car (both kms and years)?

    Good to see that your problem is solved. My respect to that 70+ automobile engineer. If I happen to be in Calcutta, I would want to meet him :)

    What were the 2 relays changed?
    Would there be any possibility of the short circuit they created affected any other electrical part?

    Learn to do things by self is one of the skills you would acquire (or sometimes forced to), when using European cars. Good luck !

    Hi There,

    To understand my problem, you need to know a bit about me, and if you want to understand the Vehicle's problem, kindly skip the first paragraph and then Continue.

    Para #1 (You may kindly skip this part)

    I have done 3master's degrees in Civil Engineering, one in Mechanical Engineering and the third one in Valuation. I am also a Chartered Engineer. I mainly work with different state Govt., Central Govt, and nationalized Banks as their technical Auditor, Structural Consultant, Consultant valuer etc. I am also into academics and teach B.Tech / M.Tech students, as well as mentor the budding valuers. The reason I introduced myself is just to inform that I have ZERO knowledge in Electrical and Electronics. And at this juncture, where my skills are proactively challenged each and every moment, it is simply not possible for me to study Electrical and electronics so that I can take care of my Car.

    Para # 2 (The problem with the vehicle).

    Around 4 months back, my car developed a problem, that, whenever I put the Key into the slot and turn it on, everything starts to function except the Fuel motor. So, I need to on/off it multiple times (Not cranking) so that the glow plug gets very heated and after maybe 20/30 min later the in-tank fuel pump starts working. For this, I need to carefully listen to the humming sound and once the pump starts working Crank, Crank, Crank... suddenly the engine comes back to life. Then onwards, I can drive it 500 km, and it runs as buttery smooth. But if in case I need to turn off the engine, I had to go through the same pain in the arse. The problem was not associated with the Cold start issue, it was the car's whims and fancy when to give me trouble.

    It is a 2009 model and run approx 86000 km.

    To sort out the issue, at the very beginning I called the Fiat India Helpline no and got the contact details of Fiat-Jeep ASS, called them and asked for an appointment, the lady who picked up my call, informed that certain Madhumita will call me immediately. But no call came.

    Then after waiting for the call, I went to a trusted mechanic, who routed me to an electrician....
    1. Who checked the car and informed that the Starter - the alternator is not working properly and that is the issue. So, both Starter & Alternator Changed. But the problem remained there, he asked me to change the glow plug and I changed the same, then also no Update or healing of the wound.
    2. Next visited at least 15 nearby garages and they were either denied to service the car as it is sensor dependant, or out of sheer greed agreed to rectify the issue but asked for so high price that I had to come back home. One of them even told me that 'Vaiya apka engine hi to kharab ho gaya, isko banana padega and it it will cost u around 70K."
    3. Next, through Justdial, got a bunch of contact nos of Diesel engine specialist and checked the car to all of them, many of them checked the Rail, injector, nozzle etc and found all of them are okay.
    4. Next, someone referred me to Bosch Diesel, and I went there, they told me that the High-Pressure pump has a leakage and its sucking air then feeding it to the fuel supply line. If I repair the leakage, then starting trouble will be vanished. I told them change the O Ring, seal the leakage with Loctite, but they denied stating the reason that the HP Pump generates around 2000 PSI pressure and then nothing can seal it. The only solution is to remove the HP Pump and change the entire rubber gasket kit and 3 plungers, which will cost me around 16 k (Plus/Minus).
    5. Checked the car at Super Diesel, Nikhil Motors, Go-mechanic and many more places but they were unable to identify the issue as the car is not getting detected in Scanner.
    6. I, from the very first time, were guessing that the problem is almost nothing and but a short circuit, which is not allowing the Current pass through In-Tank diesel pump and hence whenever the connection establishes its started to feed oil into delivery line, then to the nozzle, then to rail and then to the injector. Everywhere I asked to check the Low-Pressure pump but no one was ready, some of the mechanics informed that they do not work on LP Pump, and some of them blatantly told me unless the problematic area getting detected by a scanner, they will not touch the LP Pump.
    7. So during these 4 months, I was kinda frustrated with the car, the reasons behind (1) Since Feb 2021 I am facing a severe neurological issue and spending almost 70k per month for that. (2) My daughter has gone through a massive surgery and lost lots of blood, after the OT, the surgeon told me and my wife that if she survives 24 hrs, the chances of survival shall shoot up to 80%, and in case she manages 72 hrs, she will have no further complication. Being a father of an 8.5 yrs old girl, my priority was to save my daughter at any cost, that too at a moment when I can barely walk just for 2 minutes.
    8. Anyway, she came back home without any complications (as of date), and the frustrated me was in dilemma to sale of the car or keep it aside and purchase another car.
    9. Meanwhile, I got another Auto electricians contact no, and called him, at the very first I informed him that Dada (we use this salutation whenever we address some gentleman irrespective of age) the problem lies with LP Pump and you need to check the electrical connection only using a Multimeter. In response, he said that the is a fellow of that Ambassador age and dose not understand these CrDI or FI technology. I request him with the folded hand that just check the car, using multi-meter, his skill and knowledge, I even assured him that I will personally do the laborious job, but I need his supervision. He ultimately agreed and ask me to bring the car.
    10. When I met him, I found he is aged no less than 70 years, he asked me to show and open the LP Pump, I did that, then onward he started working by his own. After 2 hrs of sheer hard-working, he found 2 relays which are melted inside and creating a short circuit, again re-confirmed the same he did a continuity check, and found an error, then he broke the plastic (box part) of the relay and showed me that form outside all 4 legs are separate, but from inside, they are touching each other.
    11. The relays are located inside the cars fuse box, changed them and ask to do test drive as long as i wish.
    12. I restarted the car more than 20 times and Voila, every time it worked.
    13. I asked him about his fees and cost of the relays, in response he replied including all I need to pay Rs. 400. I paid Rs.500, four hundred for his work and Rs.100 for buying some sweets. As well informed that as long as I keep the car, If I face any electrical trouble. He will be the only saviour.

    Thats all my dear............ (too long, but may be worth sharing).

    Thanks for sharing the details. This will help others if they face similar issue.

    This is very strange indeed.

    You should be appreciated for your endurance (also to personal resolving personal issues) to find the root cause => deducing it to low pressure pump related by yourself and then asking the old man to find what exactly went wrong.

    See, it is not something to be bragged about. I am very much habituated to driving US/EU-based cars, and I feel much safer in those cars. Thought the fiat is 11 years old and 86K Kms on Odo, it is meticulously maintained and all parts have been sourced through BoodMo. The reason I took so much pain to rectify the issue ...
    1) The build quality - It's like a tank and I feel very much secured inside the car.
    2) I have paid Tax till 2029, so if I sell it in 2021, i will miss flat 8 years of Road tax.
    3) All recent days ars are nothing but tin can( not in a derogatory sense, but in build quality).
    4) I will never ever drive a Maruti except the 800 model.
