2.8 fuel pump, think it's dead

Postby Noel » Sat Apr 15, 2017 8:31 pm

Trying to get my 2.8i going again after a year sitting around doing nothing.
20 litres of fresh petrol, new battery.
Cranking away, no firing.
Opened fuel line at filter, no fuel pressure at all.
Checked for voltage at the terminals on the pump, zero when cranking. Dammit.
Pulled relays and fuse out from under dash. All clicking away properly and fuse ok.
Re checked at pump. Found one of the ring terminals was actually off, so re crimped it, now 10-11 volts at pump but still no fuel coming through.
Took battery off and connected it direct to the pump. All the pump does it make a dull clunking noise and pull 8amps of current. No whirring or anything useful sounding.

So this needs a new pump doesn't it? There's not anything else I should be doing to make it work is there?
Bit of a bummer this as the pump is fairly new and probably only run 2-3 hours since I put it on a couple of years ago.

Not missing anything else am I?

Does sound like the pump. I'd be inclined to take it out and give it a little tap with a hammer then connect it direct to a battery again to see if it will unseize. Obviously you need to plug the fuel pipe off the tank with something to stop it leaking while you are trying to persuade the pump to work.

Thanks think I'll have to drain the tank as when I had pump off last time I tried to plug it and it was a total shambles and I had petrol everywhere!

Hi,
That's not good! I assume it wasn't a genuine Bosch replacement?

Nope it was one of these £50-60 pattern ones that seem to be the norm now.
I got it from eBay, "Sytec" branded. Matt Lloyd racing or something? Anyway it went on nearly 3 years ago so hardly gonna get a warranty claim out of it.

Just back from Euro car parts with a Vemo branded replacement which was £60 with their Easter weekend discount so will see how that goes.

I did try getting the old one running off the car but no amount of whacking it or direct application of 12v seemed to make any difference.

Hi,
You say that you've only run the car for 3 hours in the past 3 years, I wonder if sediment/rust from the tank has caused the damage to the pump?
It might be worth thoroughly cleaning it before fitting the new pump.

That's very possible but the tank drained clear with no bits in it.
It's had about 20 litres of fresh petrol through it which I have drained and chucked before putting more fresh in.

New pump in and all working ok now. Kids went berserk so we spent half an hour driving it up and down the street.

Now time for a large scotch!
