Can anyone help me please? I have a Fiat punto 1.2 diesel. Had no issues till now. When I got started, sometimes the engine keeps turning and they want start the engine up and other times when I turned the key it's not turning the engine. I have had a starter motor replaced all the glow plugs replaced. This is an intermittent fault and become very unreliable. Is anyone aware of his fault thank you

Hello, Nap... I am thinking that it may be something most who live in moderate climates don't think about. Does this happen on cold mornings? Glow plugs can take time to heat. Try turning the key to ignition and wait the count of 10 seconds prior to attempting to start. Then I would consider checking that you have a battery with the correct amperage to crank a diesel engine, though it's only a 1.2 liter, diesels require more cold cranking amperage than their petrol counterparts. Check the cold cranking amps for your installed battery against specifications, or have a qualified battery tech check that for you (very simple test). The specs for your battery make, model and age should tell you what you need to know.
This engine should start within roughly one half second if properly preheated. The next thing to check is the quality of your diesel fuel. Try to find the most trusted brand (for me in Italy I find quite a difference by using IP Stations) and stay consistent.
Next check your air and fuel filters. Since diesel engines require only compression and fuel plus air to run, that leaves preheating, then delivery of fuel and air in the right proportions. Filters are the easiest fix, then injectors would be the next to check. Poor quality fuel can foul injectors. It is important to occasionally drive at higher RPMs to burn off any potential sludge. See your Owner's Manual for instructions or your mechanic in that regard.
Hope this helps!
