Question Panda Fuel Pump Question

Sorry to ask another fuel pump question...

My Panda just wouldn't start this morning, so I'm going to change the fuel pump to see if that helps.

Does anyone know if the fuel pump from a 1994 Uno 1.1 ieS is the same part as the one in my 1993 Panda 1000 CLX?

If so I know the Uno pump works, so I was going to swap them at the weekend to see what happens. Thanks.

Not off the top of my head, but if you have a VIN for the UNO, I can compare part numbers with the Panda - if the UNO is on the parts CD.
I should be able to look at it tomorrow night.

PM me if you don't want the number to go public.

Re: Panda Fuel Pump Question

Well, your Panda is much the same age as mine - manufactured january 1993, whereas mine is december 1992.

Unfortunately, either there is an error in the UNO VIN, or it's not on the CD I have, so I can't compare part numbers.

Are you certain about the number? - actually off the car, not a MOT certificate (which is sometimes wrong).

Smile Re: Panda Fuel Pump Question

Hi, I've owned 10 Pandas so far and almost all of them have had fuel supply problems.
I can't give an authorative reason, but.........
I now fit an inline fuel filter just before the pump and clean it every 3 months. The problem has completely vanished.
I can't explain why.........but it works for me.

Re: Panda Fuel Pump Question

There is a large in line filter as standard on injected Pandas, it's located under the bonnet on the UK passenger side, just behind the washer bottle.

It's probably supposed to be on a 24 month replacement - the one I took off mine when it was 9 years old looked like the original.

It didn't help with my intermittant starting/spluttering in the first 100 yards problems, which may still be due to the head gasket I haven't got around to changing yet..

Generally it can be provoked to start first time by depressing the accelerator a couple of centimetres at the point of cranking when cold, then releasing immediately it fires up.
It's possible that the stepper motor isn't opening the throttle enough, although it does operate, but the spluttering which sometime happens towards the end of the road from home is often accompanied by considerable steam from the exhaust.

My opinion is that my starting issue is due to a couple of drops of coolant in the odd cylinder or two, and the extra mixture from the push on the throttle is sufficient to ignite despite the dampness, whereas the normally provided starting mixture isn't.
If it doesn't fire up first time it needs a lot of cranking with part throttle to start, and it will splutter slowly into life with a lot of petrol smell.
The plug leads are good, as are the Bosch super 4's.

Spark and fuel and air and compression (13.something bar on the three I could get the adapter into) all in the right place at the right time, and no go must include a spoiler of some sort...


Sorry to ramble on.

Hi John, I double checked the Uno VIN and it does seem to be correct. The parts number for the car is 4623998 if that is any use. Cheers.

Hmmm



selecting type 146 for UNO gives model year 1998... which is probably the 158 Mondo... I don't think the CD works properly, or it's not on there.


Sorry.


Looking again at the Panda, there was a change of pump in march '93

*************** MODIFICA 0517 **************
OGGETTO : NUOVA POMPA ALIMENTAZIONE TIPO MARWAL IN SOSTITUZIONE DELLA POMPA TIPO WEBER
ATTUAZIONE : DAT 03-1993
SOTTOGRUPPI : 1020001

******************************************

which in Anglo is probably - replace Weber pump with Marwal - yours should have the Weber, if it's original.


Quite what UNOs were using then is anyones guess, unless there's a different CD out there (or one that works correctly on the UNO selection).

Unhappy Re: Panda Fuel Pump Question

Well, I've finally given up and booked the Panda into a garage for Thursday morning. My wife is driving the Brava and I need the Panda as I'm not taking the Alfa out on the salty roads. It would melt!

Anyway, hopefully they'll find the problem. I've ruled out a dodgy fuel pump as I can hear it buzzing when I turn the ignition. Bloody frustrating...

Re: Panda Fuel Pump Question

I had the Panda serviced this morning. Oil, filters, spark plugs, etc. I also had a replacement driveshaft boot fitted on the passengers side as it was leaking grease and had the rocker cover gasket replaced as it was leaking oil.

The mechanic (who I know and trust) couldn't find any fuel related problem, so fingers crossed it will behave.

Re: Panda Fuel Pump Question

Sorry to bring this thread up again, but the Panda problems persist. It wouldn't start for me on Boxing Day. I phoned Fiat this morning and was quoted 129 plus VAT for a new pump which apparently includes the sender unit. This is more than I paid for the car. Combined with the cost of the service this is getting expensive.

Does anyone have any last ditch ideas before I bite the bullet and order a pump?

Re: Panda Fuel Pump Question

Tee a pressure gauge in the fuel feed to the injector?

Re: Panda Fuel Pump Question

Hi Steve, "why didn't you ring me".

Use a 10mm socket and take out the 2 fuel pipes that go into the top of the pump at the tank. You only really need to take out the one on the drivers side of the car. (red one if I remember rightly) Hit the area around the pump a couple of times with something heavy but non metalic then turn the engine over. Watch "carefully" for fuel coming out of the pump. It will spurt out. You may have to do tis a couple of times but it will work. Once the fuel starts to flow put it all back together and it should be ok. I think the pump loses pressure somehow.

You don't remember me you telling you to do this do you.

If the problem does persist give trevor Christie or Martin Boyle a ring as they might have a pump.

By the way the car had new fuel filter. oil, oil filter, plugs put in not long before you bought it.

P.S A guy called McQueown has been trying to contact you about buying your Uno.

Stu
