Just taking a count on the amount of people that have had, or are having fuel starvation issues. This is mentioned in several differant areas--but it seems to be happening more now a days. So I started a thread
If you have had this please post and what you did about it.
thanks

Added 2nd fuel pump

Good to 1/4 tank or better with both running...even on Fast long LH sweepers that used to cause problems all the time

I had a huge problem with starvation, I found the stock pump could not keep up in certain conditions - last third of a tank + hot engine + 6000 revs.

Found mostly during "spirited" driving (obviously!) I would hold 6 or 7k in hopes of an overtaking window, then when I finally gave it some real throttle it would just die. If I backed off, it would recover/catch up, but if I persisted trying to get revs and power, it would eventually roll to a complete stop!

Naturally, hard to replicate for the dealer's tech, I was in twice with the problem.
Tech is riding along with the WDS on his lap, and I'm trying to use as much gas as possible without breaking (too many) laws - fast spurts up to high speed on the highway, then braking and repeating. Not much results, so we head back into town and THEN it kicks in - no power, car is going slower and slower, I'm going down thru the gears, but there is not much on tap, now I'm holding up traffic and the '8 is creeping along.

All the time the tech is staring into his WDS, saying "No, nothing wrong, no codes, everything seems normal..." Eventually I had to say that ".....it was good that nothing was wrong, but could he help me push it to the side of the road?"

The fuel pump and resultant power loss/stall outs seem to not throw any codes in the computer, the only symptom they ever detected was a slight mis-fire on "cylinder two" as it quit.

New pump on warranty (it's a bit piece of kit, has the level sender built in) and now it is BETTER than ever - must have been "weak" from day-one! No high rev hesitation at all.

In mine I replaced the stock drivers side pump with a new one...and put the old pump in the passenger side tank on a switch.

With the new stock pump I have had only one episode of cutting out...in a long fast LH sweeper pushing about 1G at about 1/4 tank. I turned on the second pump and it was good on the next lap and good down to about 1/8th tank.

I think if I had the problem again...I would replace the stock pump first and see if that fixes the problem. I'd bet it would fix 90% of the problems

word.
I bet this is what happened to me on the dyno when i had a engine shutdown at 8K. We never did find out exactly what happened.
However I cannot replicate my problems except in one turn at one track. I dont think I want the tech to come along as a rider. Maybe i will have to replace myself.

It's a cheap experiment...only about $150........

I I had to do it again...I'd replace it myself with the dealership paying for it if it fixes the problem. Problem is getting them to believe fuel starvation in 1G LH sweepers is a design flaw...or a defect in the car

I've had this happen at 2 different location. Always when the car has less than 1/2 a tank of gas. Both were higher speed LH corners.

Sweepers with about 1/8 tank of gas did it. So I keep it above 1/4 now. No problems since then.

SpeedSource sells a track kit, but they need your gas tank and a wad of cash

Just to let ya know - My POS car had Fuel Starvation issues with a F'ing FULL tank of gas.

(sigh).

For a POS car...you had a pretty big smile for the first couple of runs

The pump thing is a PIA....

dmp

It's just so full of 'little things' - I've never had a car which was so fun, yet so full of bs nit-noid stuff...that's all

Paul_in_DC

LOL! Never owned a British Leland product, eh?

Razz1

Better than the Diamonte I sold. Every sharp rgt. hand turn at 30mph and the fuel would cut out and stall the car.

I had the same thing with my Cushman motor scooter in 1963. Take a right handed turn and it would slow from 25mph to 15. Aggravating. You know how long it took to get to 25mph on that dang thing.
Anyway as soon as I get a free $190 I guess i will be chunking out the back seat and getting to work. I just wonder how will I be able to see if that fix's it. I am not due for Roebling again until next spring---sighh.

Front straight WOT in 4th at Watkins Glenn with slightly less than half a tank. Never run with less than half a tank now and haven't had the problem since.

I've had it with a little over 1/4 tank indicated in a 180 degree LH sweeper. It took long enough to recover that I ended up coming to a stop and screwing up my rotors.

I'll just keep 1/2 tank or more.

EDIT: Brake rotors, not the engine rotors.

i think if the pump ever runs dry then it is more prone to have problems again as the pump is lubricated by the gas.

Run The Rock with me. Talk about high G left turns!!!

Anyone who has had the Dealer replace the fuel pump care to do me a favour? If you've got your service paperwork, and could scan or photograph it for me (edit out all your personal data), it'd REALLY help my dealership; they've yet to experience a complaint.

Thanks

TA yea baby----but the banking drains all the fuel to the left tank anyway!
Yea my dealer(good guys) havent had any issues either and as far as they know there is no tests to check this.
