How many cranks to start are normal?

777 13
I have a 1992 900 16v non-turbo. It takes about 3 cranks to start. I define three cranks as: whirr whirr whirr broooom (pretty technical huh?:D ). I have owned an '89 turbo that used to start on the 1st or 2nd crank every time (just a tap of the key).
What is the deal here? Is it normal for my year/type of car to take 3 cranks to start. Are there other cars out there that take three cranks and it is just accepted?

If there is something wrong I would like to fix it. Any suggestions.

Thanks,

Matt

Both my 8V turbos fire/d up first time ... "Click ... Boom", but IIRC, my 8V 900i needed a couple of cranks ... "Click ... Cough Cough ... Boom" :cheesy:

I think it's to do with the fuel pre-pump. When you switch the key to the pre-crank position on the turbo, you can hear a humming from the fuel pump which then stops after about a second or two until you fire up. On the NA model, the fuel pump does not start until you turn the key ... hence the extra couple of cranks. It might be an age related thing though, since both my turbos have been post-facelift and the injection was a flat nose.

One other thing that I left out, is that it seems to start better if I push down on the throttle a little when cranking.

Do the people in the "Click...Boom" category have to touch the gas pedal when starting?
No way ... in fact, the owner's manual says not to.
