Question about 2000 BMW 3 Series

1 Answer

It always takes two times to successfully crank my car in cold weather, especially if it has been sitting outside overnight. I have a 2000 323ci BMW && lately, the temperature has been dropping to only about 50 degrees but my car will never crank the first time. I am trying to figure out what is causing this problem and how can I fix it?

Sounds like a fuel problem... possibly the fuel pump.

Cold weather battery drain


Cold temperature is discharging power from battery. There must be a temp differential between shop and outside. Regardless to where the battery is it should not discharge power that quickly you may need a new battery

2004 chrysler pacifica will not start when outside tempeture is below 20%


Take vehicle to Autozone or Advane Auto and have the charging system checked for free. Batteries have 2 capacities. CA, cranking amps, warm weather and CCA, cold cranking amps, cold weather. Suspect new battery required.

Sits overnight and battery drains


Did you check the battery? Take the car and have a load test preformed on it, simply checking the volts will not tell you how the batt is doing.

Also check for any trunk lights, hood lights, glove box lights that are not going off.

Hope this helps.

1998 Catera will not start if it sits overnight in cold weather


It can be worn distributor cap/rotor or coolant temperature sensor.
To check it leave car outside, try to activate if it is not use the hair fan and worm up the distributor cap area

If it helps replace the distributor cap/wiring/spark plugs. If it doesnot help warm up the coolant temperature sensor:

and, if no help, spurk plug area.
Also good idea in cold weather use higher octane fuel or regular with octane booster or injectror cleaner added and ask the mechenic to put winter oil (less viscous) for winter time during oil change.
Good Luck

It is possible that some of the glow plugs might not be working. This will cause a hard start and smoking condition especially in cold weather.

Hard starting after sitting awhile


My 98 Jimmy runs on synthetic oil and starts well after sitting in cold weather. If the weather is the problem, try checking that. If it is warm... sorry no ideas.

I have seen this issue a lot- especially this time of year when it's starting to get pretty cold overnight around here.

If the vehicle won't start right away, stop cranking. Turn the key to the ON position and depress the accelerator about halfway down and then crank the engine.

This should resolve your incident. This is actually the procedure that was supplied to us directly from Nissan for cold weather starting tips.

Because cold starting requires a richer air/fuel mixture, the computer REALLY richens the mixture.


I hope that this is helpful to you!
