Bad start ups, when colder then -10C

These past coupe of days, my e30 is really hard to get started when the car is cold. It takes about 4 or five turns of the key to crank it over......

I have replaced:

Fuel lines
Fuel Pump
New Gas tank
New Spark Plugs
New Distribution Cap
New Rotor

What else could it be? Dirty injectors?
Jay

No, it is not the battery, it is less then 6 months old, and plenty of cranking power......

Lennon: The car has 215,000kms.........

Yeah, thats what I figured, it only does it when it is really really cold out.
Anyone think I should add some STP Fuel Injector cleaner or is that stuff bullsh*t?

That wont really help.. and it can burn your injectors and or O2 sensor.. when it's cold like this, a fuel line antifreeze can help the cold starts.

Good idea, I couldn't even start the car this morning. Drained the battery, going to give the antifreeze a shot.

5w30 sounds good,i guess its the injectors or the fuel pump or if its really really that cold then fuel viscosity is very thick.

Another thing, its always recommended that you always have at least half a tank of gas so your fuel lines don't freeze under extreme low temperatures.

It has to be th injectors I have replaced everything else that has to do with starting problems.
I bought a block heater for the car which I think should help aswell.
