Check the coolant temp. sensor for the Engine ECU as it might be faulty and gives wrong information about the engine temp. so if it feel the car is cold it'll ask the Engine ECU to give command to the fuel injectors to flow more fuel into the firing chamber and then it'll be fluded and won't start easily..

The key turn but the car dont start, but when i kick start it it start and i wont have a problem the hole day starting only in the morning


The battery needs to be replaced. After the first start in the morning the battery gets charged and the engine is also "hot" making it easier for the starter motor to turn it over. Therefor less current is drawn from the battery and you get a start every time. In the morning the engine is cold making it difficult to turn. The battery rested the night loosing some charge and is also cold which affects the current it can deliver at that stage. With the cold engine it is not able to turn it fast enough to get it started. A new battery will solve your problem.

Motor starts then dies several times when cold


Sounds like the cold start solenoid. It is designed to keep the engine running at a set RPM until it reaches a specific engine temp.

Why is my truck hard to start on cold mornings


When you park your truk at night,the engine is warm/hot.Now its start to cool down.In doing so,condensation collects under the hood and around the cooling off engine.The condensation freezes,making everything wet,including the wires.Tht's why its hard to start in the morning.
Trick is: when engine is parked and off,place a heavy blanket over the engine,close the hood.The blanket will absorb any condensation.Just remember to remove the blanket in the morning before you start the engine. 25283814-gdc3ufgmlwaqnv2deqjxyac2-4-0.jpg

I have abmw 3 series 1996 parked it last night perfectly ok this morning it wont start the engine turns over very quick as normal could it be because its damp and cold outside what do you suggest?


I would replace Distributor Cap & Rotor; and especially all Ignition Wires (aka: spark plug wires) When it is damp outside, old and possibly cracked wires is the leading cause of engines not starting due to wires arcing (throwing sparks to other parts of the engine) and causes no spark where it is really needed and that is at your spark plugs so the engine will start.

Cold morn - not starting. Car was moved a few feet night before.


OK, so starting the engine uses a lot of battery power, and the engine needs to be left running a while to recharge the battery.
When it is cold batterys don't hold as much charge (not quite the correct technical term, but I don't want to go into battery mechanics and chemistry here). You either need to pop it on a trickle charger or let it run for at least 15 minutes.
