335 start time on cold engine

[boss2k]

What would be the expected time taken to start car on a cold engine, is 2-3 secs normal ?

This is directed to to 335 owners

Thanks

2-3 seconds is in "long crank" land, if it's doing it consistently, it means the HPFP is getting ready to check out.

335 should start almost immediately, even from cold. You don't say what year your car is, or what level software you have. There is new software available from BMW which helps this problem.

Take it in to the dealer for an HPFP test before it dies on you going down the freeway -- which it will, sooner or later, once the long cranks start.

I agree...my fuel pump has failed 3 times and it started with long cranks on each occasion. Not a bit deal...but get it checked.

Less than a second for me.

Couple of months back it was really taking long to start and took it to the dealer and they upgraded the software and after that the car takes consistently 2-3 secs to start, 2-3 secs is a guess but there is no cranking starts. That time dealer mentioned HPFP is fine.

So should the car start within a sec normally ?

Even in sub-zero temps my 335 starts in less than 2 seconds.

Less than a second except for (1) prior to HPFP replacement and (2) a low pressure fuel switch replacement.

within a second in mild english weather :)

3-5 seconds is BMW's long crank time for the 335

When I first got my car, all it took was a quick press of the engine start button the engine would ignite. Then as the HPFP was going the crank times hit 20-seconds until it threw a code and the dealer replaced the HPFP (9500 miles). Now, at 12k miles, with the new HPFP, the engine ignites with a quick press of the engine start button. Start time is a second at the worst.

Under a second. If it is taking long enough for you to wonder about it, it's taking too long.

My car is at dealer and its been diagnoised with HPFP failure, technician tells me they will be replacing with new pump , part #13-51-7-613-933 , is that the latest and greatest or is there a PN# that ends with 943 which is better

Sorry...no clue about the HPFP number...it's just sad that they make us go through the process of resetting the computer first. If all of us posters knew your HPFP was going bad, then we darn-well know that the BMW tech's knew it was going bad a couple months ago too. They just have to follow the rules and reset the stinking computer first. Oh well...such is life. It just annoys me that you could've had the fuel pump replaced a couple months ago, and saved yourself the trip and the hastle now. Gripe over.

Surprised that nobody has asked the OP to post a video of him starting the car...

that would give some better responses.

HPFP replaced yesterday at 9600 miles, part #13-51-7-613-933 installed. I am told this is the latest one by BMW , lets hope it lasts.

Have one question, can HPFP failure be considered as a lemon case if it falls within the lemon rules for that state or it cannot be considered because BMW extended warranty on it for 10yr /120 K miles?

Most lemon laws allow the owner to ask for replacement if the car is out-of-service for x days. In WA state, at least some of these HPFP problems might qualify, but the period is usually too long. Some might qualify because of the number of attempts to repair exceeds the limit.
