Long cranks after HPFP replacement

Citizen Z · 07-23-2009, 06:40 PM

After getting my HPFP replaced at 18,300 miles, I began and continue to experience long cranks, between one and four seconds, every cold start or any time the car is started at high altitude (above about 7500 feet). There are no associated lights or codes but it makes me embarrassed every time I come out of a restaurant and my car sits there and cranks and cranks instead of just firing up. Has anybody else had this problem?

still have long cranks. car was at the dealership this week, they performed a HPFP check (I might upload a scan of the sheet later) and nothing was wrong.

Probably they replaced the hpfp with the same part number pump. There's a 2nd generation hpfp whose part number ends with 881, and apparently has the problem corrected.

By the way, I had the same problem at 9,000 ft where a live at. It's still the hpfp.

I had mine replaced and it is cranking long again, for about 4 seconds, every once and a while, normal altitude.

C'mon, only 10 people have had a HPFP replaced? Anyway, after my car sat at the dealer for a week while BMW AG repaired their ISIS server, the dealer finally diagnosed the issue as being a faulty fuel pressure regulator.

Had my HPFP replaced at 4K Km's and have 13.5K Km's now on the dial with no long cranks..Starts immediately..

Take it back to dealer..Something is amiss there..

Its been at the dealer; see my previous post. The problem is apparently a faulty fuel pressure controller.

Replaced HPFP @ 4K.
Long cranks every once in a while. @ Sea level.

that is your gas cap bud :P

oneintheory · 08-04-2009, 02:09 PM

My HPFP is going to be replaced again tomorrow.

I just picked up my 1er from the dealer; all is wonderful. After two weeks of hell in a 328i, which the SA agrees is the worst vehicle BMW sells from an enthusiast perspective, all is well in the world. BTW, damn, the sport seats in the 1er are comfy compared to the standard seats!
