Question F-1 Pump, the question.

Hello Friends,

Does anyone can explain, why F-1 needs to engage every time drivers door is opened? It would be more easy to understand, if the pump got engaged after ignition, but just to open the door!!
Thank you, Michael.

And worse, when you open the doors with the remote, the F1 pump engages. Then you open the door it engages again - why twice?

It does have a little intelligence as it doesn't engage when the door is opened after the car has been running.

Thats a safety measure , not possible to engage any gear with the drivers door open

I meant the F1 pump doesn't engage- not the gears. In other words no "whine" when the door is opened after the car has been running.

Exactly my point , its a safety feature, door open pump doesn;t cut in therefore the system isnt up to pressure therefore unable to select a gear therefore unable to drive off with the door open and cause injury /damage therefore a SAFETY FEATURE i rest my case m'lud

last night was the first time I noticed that after running the car for 1/2 hour--when i opended the door it made a quick noise instead of the normal 3 second wine. I assume that is normal, and I barely heard it.

F-1 pump must be working just fine.

But --yes I had thought it strange that when you hit the remote it kicks in to prime, then does it again when the door is open. I have made it a point that if I need to get into the car while its in the garage to retrive something from the car--I always go in through the passenger side.

Whats a tell tale way to know if the F1 pump is going bad? It seems its a hit or miss thing randomly since its an electric part, if it goes it just goes? Any good preventative measure or any cost effective way of checking on it myself?

Pump failures are rare. But when they do happen, it is usually one of two things. Either the pump itself stop working, or the pump relay sticks open and fries the pump.

As for pump only failures, once it goes it goes. I guess you could have it rebuilkt once per year but that wouldn't be cost effective.

As for relay failures that could result in a pump failure, you could always replace your relay each year. I think someone mentioned a relay cost of about $75. Truthfully, relay failures are also very rare. Our cars have lots of relays in them. I'm certain very few of us have ever replaced even one of them.

It so happens that my new F1 relay arrived at my UK apartment today and I will take it back to Ny next week and install. Worth the mney to avoid frying the pump and my mechanic recommended it. Gbp38 which is $62.50 on today's xchange rate. For any Americans who want one but don't want to pay the crazy shipping charge, feel free to pm me and I'll accept it at my UK adddress and bring them back to the us. I'm back and forth every 10-14 days so no big deal.
