fuel pump advice

[redjohnson]

starting the griff 500 from cold this morning managed to stall as it was starting to warm up - then had problems restarting which cured with a blip on the throttle (i assumed it was flooded)> anyway now i can distinctly hear the fuel pump pumping when the engine is running. i'm quite new to the car so does it always run and i have never noticed? or could i have created a pressure problem in the fuel system with my cranking / blipping / stalling activity this morning? any help appreciated.

also while i'm here the allen screws (3) that hold the door latch assembly to the chassis keep working themselves loose leading to door opening and closing problems. does anyone have a simple suggestion for solving this.

thanks for the help.

My fuel pump creaks and squeaks like a couple of hyperactive rabbits banging away, getting faster as I put my foot down. I'm not kidding you, once after I stopped there was this almighty groan from the fuel tank area as well. Scared the crap out of me!

Edited to say, I also stalled the car on numerous occasions when I got it. The thing wouldn't start for hours afterwards! Now I keep the revs at about 1000rpm for 30 seconds after starting - no probs. Also think the car needs a few more revs than usual to pull away without risk of stalling.

maybe helpfull to try a drop of liquid thread lock on the screws to stop them coming loose once you have the alignment correct.

The car is set to be very protective of the cats. Thus the ECU will close down if the engine is flooded - it doesn't like neat fuel getting through to the lambda sensors. I have managed to stall the car on three occasions (about once a year) from start up when it's not running at its best. Usually it's quite a difficult engine to stall.

Frustrating though it is, the only answer is to go away for 15 minutes, find something else to kick and swear at and then come back with a nice smile on your face. Usually takes a further ten or twenty miles to settle down, in my experience.

Just put it down to owning a car with character

As far as the fuel pump goes, and don't forget there's a return valve which sounds like a bee in a jamjar too, whilst it's comforting to know it's there and working, I don't think you should have an intrusive continuous noise.

The ECU isn't that smart, it'll keep chucking the fuel in anyway. But if you've flooded it, your best option is the 'rocker cover' solution. Get out of the car, lift the bonnet and spend fifteen or twenty minutes wiping the oil off the rocker covers and polishing them. Which may seem pointless but it takes your mind off the problem while the inlet manifold dries out and the battery catches its breath. Unless there's something fundamentally wrong with the engine, you stand a good chance of it firing up OK after that. Sometimes if you're lucky it'll restart immediately just by cranking it over with plenty of throttle but if that doesn't do it the 'rocker cover' solution is your best bet.

The problem with the throttle is that the ECU can get confused and think you want to welly and chuck even more fuel.

On the 520 I cheat and switch the pumps off while under throttle to clear the engine and then start again but this is easier than removing the pump fuse on a Griff.
