How can I make my car startup faster???

I have a 1971 2002 and I just started using it as my daily driver but it's kind of embarrassing when it takes a good ten seconds or more for the car to fireup. Sometimes it fires up right away, especially if I've been driving it for awhile but usually it doesn't. I have a new battery installed. Could it be the alternator? Any suggestions are greatly appreciated. Thank you.

do you have the original starter in there? You may want to consider replacing with the M3 starter - run a search

Make sure you dont have fuel leaking back to the tank. If I let my 02 sit for a week it takes 10 seconds easy to start it, but if I let it sit for a day she starts after a pump or two of the gas. But like others have said, do a tune up (tune the carb, time it, file points, etc), then try it again.

Is there a way to check to see if I have fuel leaking back to the tank? Thanks.

And after you get it tuned up properly, you've got to know your car's starting technique. Each of my 02s dictated a different set of rules. For example, my '76 requires, with a cold motor, two full pumps to the floor and then don't touch the throttle until the engine begins to catch. But warm, you must give it about a third throttle and hold the pedal there: it will catch immediately. If you don't adhere to those "rules," you can crank it for a long time. My point: unlike modern computer-controlled cars, you need to learn the right choke and throttle approach.

Best way I can think of is put a clear fuel filter inline by the carb, it should stay fullish, if it's totally empty it's probably drained back towards the tank. The other thing you could do that would work is pull the hose off the carb and put it into a clear jar and have a buddy crank, you should get some fuel but then a bunch of air, then fuel again if the line drained back to the tank.

If it's a '71, does it have a manual choke? Do you know how to use it properly? ; ) Look for a choke lever opposite the ignition key in the steering column.

Have you checked for fuel leaks, especially at the start of the rubber hose in the engine bay by the firewall? The pump will suck air and it'll be hard to get fuel to the carb if that hose starts to leak.

Is you ignition system in good shape? Are the points recent? Condenser? Have you tried swapping in a spare ignition coil to see if there's any difference? A failing coil will cause hard starting. Are the spark plugs in good shape? New cap and rotor? Keep in mind most fuel problems are ignition : )

Good luck.

I have a Weber carb so the choke is disconnected. I don't think I have any leaks, I feel like I would smell it or see evidence on the ground. I feel like it's got to be something electrical. Thanks for all the tips, I'll see what I can figure out.

I'm not quite that knowledgable with the 2002's, I've only had it for 2 years but want to learn more. If anyone is willing to take me under their wing and show me a thing or two I would really appreciate it.

Thanks.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
