My 1.5 dci engin does not start

The heavy smoke is from all the fuel dumping in to the cylinders without enough heat. Can you plug the car in at might if not glow the plugs sevral times befor turning the engine over.key on few sec then off then on several times. Hope this atleast helps your cold start problem.

Get an new battery and make it one with more AMPS than you have now.

your charging system isn't working, if you replaced the battery and it worked for a few days, then its not being re charged after starting, I'm assuming you cleaned and tightened all the battery post connections when you installed the new battery , if not do so ,, charge the battery from an outside source, once you know its fully charged,, use a meter, and start the car ,, check the voltages at the battery posts,, you should be getting a reading of 13.5-14.5 volts, if not your alternator isn't charging the battery

At first blush, it sounds like the distributor cap isn't seated. Since it's happening when the engine is cold and at night, I'm guessing condensation is causing the problem. Try spraying starter fluid on the cap the next time the car doesn't start. This will dispel any condensation. If the car starts, that would be a good place to start.

Is your car parked outside the garage?If yes,try park inside and see any difference.

Hello,
You may want to try a jump start first. If the vehicle will start with a jump start it is more likely that your new battery doesn't have the MCCA, ( minimum cold cranking amps ), required to start your engine.

When it's cold out the starter needs a lot more amps to turn the engine fast enough to start.

Low CCA is seldom a problem until it's cold outside.

I hope this helps you.

This is a very, very common issue.
There are two parts to a car battery,
The first part is common to all vehicles, they are 12 volt batteries. The 12 volts are standard for all of the electrical equipment on the vehicle. ( headlights, stereo, brake lights, etc )

The second part is the amps, also refered to as, " cold craking amps ", it is the amps that start your engine, not the 12 volts.

Two batteries, side by side, identical in every way except one has 500 cold craking amps, and the other has 700 cold cranking amps.

The 550 cranking amps may start a 4 cylinder engine, but it's very unlikely that it's powerful enough to start a 6 cylinder engine, especially if it's cold outside. However, the 700 cranking amps should start a 6 cylinder with out any problems.

You very likely have a battery that doesn't meet the vehicles, " minimum cold cranking amps requirement ."

I am sorry for the long explaination, but, many people are having the same issues, and because this is likely going to be viewed by other users I am hoping that they will start looking more at the " cold cranking amps " rating, before thay buy a battery that isn't powerful enough to start their car, especially in cold weather.

I hope this helps you.

the battery may be the problem there is a rating on batteries called CCA this is Cold Cranking Amps. This is how much cranking amps the battery has in cold conditions.When it is warmer the cranking amps increase to start the vehicle.

My guess would be the battery. When was the last time it was replaced or serviced.
Batteries are rated in CCA (Cold Cranking Amps). When it is cold out the battery has to work harder to start the Jeep, in addition to battery having lower Amperage.
So your battery might not have enough CCAs to turn the Jeep over on those cold mornings.

You must live in the cold area, if the temperature is low outside than the garage, the engine start harder.
