Fuel pump

Post by Scooby » Tue Feb 26, 2019 4:19 pm

I've had Japha in the garage for a couple of weeks now and the mechanic finally got round to looking at it.

He cleaned dizzy and got the car running, only for it to die shortly afterwards.
He then put my new dizzy on it, and car fired up nicely again.

Comes to this morning, and once more, nothing.

He just rang and said he's done some additional work and thinks it's the fuel pump, since when he disconnects the pipe, there's only a trickle coming out.

Questions:
How do I remove the fuel pump (I've got a breaker with a fully working FP).
Could it be the FP relay causing issues?
If so, where is it?

As far as i know you have to drop the Tank to get the Fuel Pump out.
Would be worth checking the Cut off switch in the Boot as i had this once on my Teal and it was corroded Terminals on the bottom of the Switch that were causing an intermittent Voltage supply to the Pump.

it might even be the fuel cut off switch (in the boot) passenger side
plus when did you last change the Fuel Filter
I believe you have to drop the fuel tank to change the fuel pump (will double check)

Jon beat me to it :D

Or if you’re brave :o
Cut. Hole in the floor of the car, under the rear seat, to get to the pump :!:

Getting the fuel pump out is easy, getting to the fuel pump to get it out ,is a major exercise.
The only upside is the access to the hidden brake pipe which can then be replaced if it is corroded.
Unless you have run the tank dry( ?) I would have thought the fuel pump is ok, definitely check everything else first.

I would false feed the pump to see if it works before you attempt any repair or renewal

I gave my mechanic a replacement fuel cut-off switch, which he apparently tried.
He also ran the pump to see what the actual fuel flow was, and he reckoned it was a trickle (should be about 2 BAR I think).
Car has about half a tank of premium in it, so not run dry by any means.

I did manage to work on my scrapper last night and as described, getting the fuel pump out of the tank takes a minute or two, but getting the tank in a position to remove the pump took nearly 2 hours!!

Mind you, it would have been easier if it had been on posts rather than axle stands, but hey-ho.

Replacement fuel pump dropped off with mechanic this morning so hopefully he'll crack on today and might even be able to get it to MOT later this afternoon.

Finally, progress!

I had thought about one of those, but I don't have a garage (or at least won't have a garage soon) as I'm planning a house extension over where the garage currently sits.

I do, however, have access to a set of posts, but the scrapper is currently minus any running gear!

Had similar problems a few years ago.

My problem was the immobiliser wiring. I'd done the moby bypass. But the fuel pump wire about an inch back from the moby plug was breaking down. There was enough there for the fuel pump to work, but not enough to fuel the engine properly.
