Opel Corsa B fuel pump

Correct ... plenty of videos on YT. I did mine on Corsa C a few months ago ... Need to get a$$ in the air and drop tank (4 bolts 2 straps) ... a special tool to release the fuel pipes .. not 100% needed but makes for an easier job ... can be done in ±2 hours (would be nice to have a lift to raise vehicle). I replaced the whole unit ... best price was at "Goeie Hoop Onderdele" in Brackenfell. A full tank is gonna be a bit of a mess.

Did your pump just fail or give any indication it was on its way out?
Mine was loud but its always been quite loud since buying it...

Yip ... you could hear it didn't come on when you turned ignition on. ... after checking all fuses and relays, it boiled down to being the pump.

The higher you can get the bakkie, the easier the job should be :thumbsup:
 
Easiest part was replacing the pump, after that I struggled for two days just to get the lid to close, there is an O ring, I have no idea whether it expands when taken out or what but the thing just did not budge when I pressed on it.

Hopefully it would be easier with two pairs of hands, as I have learnt with everything on the car, you really should be proud of yourself if you manage to do any repair on the Corsa on your own and get it done without an injury to yourself.
 
Well, got the new relay.. went to the car, installed it....the car started first time...
Drove home...Parked car...put old relay in just for a laugh...
Car started first time..
Swine...

Any ideas? Nothing has been done to the car so no connections etc have been made or broken...
Just the fuel pump issue...

Fuel pump relays often get dry soldering joints on their boards. They sometimes work and not at others. Before you buy anything, open up the fuel pump relay and inspect the soldering with a magnifying glass and resolder doubtful connections.
I found more dry solder joint problems on relays than any other problems on fuel injection systems.

Mine also ran well in the morning when it's cooler, it would then misfire badly when the car has been driven for a while.

Put the old one back in and give the car a good drive around the block, sure it will act up again. But I am very happy you don't have to change the pump, although you might want to do it as a preventative measure at some point since the car has lots of kilometers on it, that's if it hasn't been changed before.

It's a sealed unit filled with resin.
 
Aaahhh...Mondays....just tried to start the car...And nothing....
So Im going to get a new pump...
I assume when its cold the resistance is too high or something?
 
R1205 for a pump with all the plastic crap and other bits and pieces...Goldwagen...(And a fuel filter!)
Car started first time when I got home...Its now at the mechanics...
Their problem now...:)
 
It honestly doesn't sound good, in my mind a bad pump that still works would have signs, it wouldn't work 100% then fail completely the next minute, I would expect some reduced performance that you can feel when driving the car, hopefully it's not a bad earth or something electronic.

I just hope the mechanics don't mess things up because a simple misdiagnosis can sometimes lead to people fiddling where they were not supposed to and causing multiple problems that causes more confusion.

Hopefully its just the pump, if its still original its done its time...And it was noisy.

I cant see it being anything else really...no work has been done on the car in a while and nothing electrical in a few years since we did the alternator and start...

But ja...we will see later...
:)
 
Just collected my car...Tank was apparently a little dirty, i got the old pump unit back so I will take that apart tomorrow and have a squizz...I cant even really hear the new pump..

Anyway...lets see whats next...

Has anyone had the fun of replacing the fuel pump? Is it a bugger of a job? Local mechanic says 3 or 4 hours?
I have the Corsa Bakkie B...a 2002 model...

Ive replaced the relay and the car ran OK for a few days but now I can hear a click with the relay and nothing from the pump...

Anyone have any ideas or should I brace myself for a new fuel pump and 4 hours odd of labour?

Can't Opel do it? If its done wrong you could face more problems.

Already done. Got a pump with all attachments (including the float...mine was a bit 'bouncy') so its just plug and play. Two pipes and a plug I think it was.

I suspect Opel would tell me to bugger off with my 21 year old Corsa.
:laugh:
