Looking for a new pump for my 52 plate abarth would the Alfa selespeed pumps be the same or does it have to be a fiat one cheers in advance guys

Luckily I dealt with this question just last week. I sent someone a 156 Selespeed pump and they fitted just the pump part into the bracket on their Stilo.

However, you could still save a lot of money by replacing just the brushes in your pump motor, if they have worn out. It's unusual (well, unknown so far) for the pump itself to fail.

Also be aware of the accumulator being a potential fault instead.

My car is stuck in first gear at mo hooked it up to ecuscan an the hydraulic pressure circuit is showing as 0.00 so I'm assuming its the pump I. Can't even start the car

Start by giving the pump a tap, to see if that brings it to life (driver's door open so that it runs). If so, the brushes are probably worn out and can be replaced.

Also look for the relay. I think it's in the middle of the fusebox behind the battery, but embarrassingly, I'm not certain. It will have much wider terminals than most relays, being rated for 70 amps. Take it out, check the contacts for signs of melting/tarnishing, clean them up, etc.

If it's showin no pressure when I hook it up to ecuscan could it be the bushes or is it going to be a dead pump and has anyone got any tips for the best way to get at the pump to give it a knock and check connections etc.

Could the accumulator be the problem if there's no pressure it was jumping out of gear b4 it totally went and lots of posts on here and alfa say the accumulator s faulty it would also be the cheapest option to try.
Is there anyway of checking it on multi ecuscan to show its defo the accumulator

I'm still confused by the last two posts. Does the pump run when you open the driver's door?

You've said it has a pressure of 0. This either means the pump does not run, or that the pressure sensor is faulty.

The pump has a two-pin plug on thick wires behind the battery tray. Perhaps while you have MultiECUScan connected, unplug the pump and use a jump starter pack to put power on the pump. If it runs, and you see the pressure rise, then you know you have a relay or wiring problem.

If it runs and pressure doesn't rise, then you know the pressure sensor is faulty. This has been known to happen, particularly after an accumulator failure that allows the pressure to spike high.

If it doesn't run with voltage direct to the plug, then you know the pump motor is faulty.

The pump is attached to a bracket behind/on top of the gearbox. Accessibility is not easy; you will probably have to remove the battery tray, or work from under the car.

This all probably sounds like a nuisance. At times like this, it might make you feel better if you imagine trying to diagnose a dead automatic transmission of the conventional type; the transmission would have to be removed from the car and taken apart, which makes it impossible to test Selespeed is reasonably logical in comparison, and you do have the diagnosis software to help. You will solve it...

Tested the pump with a 12 volt supply an not workin gave it a tap came to life so defo needs a pump would it be advisable to change the accumulator while I'm doin it

Good on you for finding the problem. You can replace the brushes in the pump motor to save the cost of a new pump. An auto electrician can help with finding similar brushes - some can be filed down to fit.

I would only replace the accumulator if the pressure was rising in short spikes to over 55 bar. I think you should just deal with the pump at this stage.

Cheers mate think I'll take ya advice on not replacing spent enough on the car as it is lol

Hi guys,

Can anybody put up a photo of the accumulator? Also the pump?
There is no sound when the door opens, so does this mean the pump is knackered?
Thanks

Hi,

I have the same problem. I've already replaced the brushes and checked the pump by hooking it up directly to the battery and it worked. But now I've placed it back still no pressure. So I'm also very curious about the accumulator, how it looks and where I can find it. So if anyone can post some pics of that. I took some pictures of the pump, so I will upload them soon. (have to tranfer them to the computer first)

its right on top of the gearbox. You can see it after removing the plastic tubes that connect the filterbox to the throttle body. Its the round black thing the size of a big orange

Thank you! I had found it already, the problem was I'm not a native english speaker. So when I found out what it was in Dutch I knew wich part it was. To bad there was noting wrong with it.
It's really frustrating, all we did is replace the brushes in the pump. now the pump works without hitting it, but not enough pressure. (arround 12 bars) While it worked perfectly before

I just bought a stilo abarth that's stuck in first gear. The guy who i bought it from told me that he's sure the pump is broken, Personally, I'm not sure. The pump is quiet when opening the driver door, but the interior light do not lighten and the display does not warn for open doors either. The passenger door does however work as it should. Anyways, I'm wondering if the broken mecanism in the door may couse the pump not to start? Also, shouldn't the display give a error message if the pump fails? Mine isn't..
