Turbo Mini Forums

posting this on here because this is where you get most sence.

right been out in my starlet turbod mini for first time tonight and all seemed well. did about 7 miles all ok but noticed my fuel pump had become very noisey but still running ok. went home and had quick look couldnt see owt wrong. went out again did about 6 miles then started losing power on any type of throttle felt fuel related rather than anything else cut out a few times but started up and was the same. managed to limp home. once left for a bit seemed ok went for little run but was just the same. noisey pump which tone changes slightly with engine revs.

im using a metty turbo pump which should be up to the demand for a 1.3 efi turbo shouldnt it. return seems ok.

only diagnostic code i have is vehicle speed sensor which i havent wired up and i dont think this will matter. im gonna connect lambda guage tomorrow and check but just wondered peoples opinion on the pump really, is it up to the job and does it sound knackered?

sorry bout noval

no longer a series, but still 1.3 turbo.

im wondering if the pump doesnt do enough

The change of tone sounds worrying, is there a pre filter?

What do the other injection people think?

tank------pump-------filter-----fuel rail-------reg-------tank

was ok to strart with tho.

its the exact same pump, filter, fuel lines and tank that powered me a series turbo and was fine with that.

no longer a series, but still 1.3 turbo.

Are those metty pumps designed for high pressure though? Like 2.5-3bar constant?

When I wired in my FPR I had the hose connections the wrong way round and the pump was stupidly loud due to being under more pressure than designed for(squeeling kind of noise)?

Fit a pressure gauge in the fuel line somewhere between pump and fuel rail. Ive only just fitted one and its helped me sort my fueling issues out this week.

My guess is that the pump is being over worked and maybe getting a tad warm?

gonna put fuel pressure guage on tomorrow night 2 see

mibby the pump has seen better days, and coped with high flow low pressure operation (carb turbo) but at the increased pressure it jsut couldnt keep the flow up enough. the pumps themselvs however should be up to the job i'd have thought, as they are an efi pump.

Hi,
They used the same pump in 2.0 Montego Efis and Efi Jags too I believe...

The pump probably is up to the job, but may be getting a bit tired. I doubt that it has anything to do with hooking it upto an EFi fuel rail though. The pump will pump what it is designed for. It won't magically produce more pressure just because it is connected to a fuel rail.

A man without a project is like a like a woman without a shopping list.

I've got a brand new efi pump that I'm not using if you want to try that.

My Metty pump is loud, but it works fine and the noise doesn't change with revs/load.

In the 13's at last!.. Just

My metro pump is also noisy, it neesd lots of padding to keep it quiet (but as I assume that you are using the same pump setup as before, you have noticed a change in noise).

Interestingly, my pump noise alters as the indicators flash.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

are you getting a steady flow through the pump?

was it easy to start once it had stalled?




(oh and, how fast was it, was it what you expected???)

I know this sounds stupid, but when i stretched a fluroline silicon hose over mine, the inside split without me knowing, plapping over the end of the pump which cause a reducton in flow, thus causing a backup to the pump and making it noisy! but a replacement black shit hose on there and problem solved! Of course it might not be that easy, just going on personal experience!!!

"Cars are a lifetime of pain"

the pump mis defo noiseier than previous. just ordered a new one, gonna check fuel pressure tonight and maybe try another reg.

thanks

no longer a series, but still 1.3 turbo.

What is between tank and pump? The original tank strainer still fitted?

oh - I just re-read it... The metro pump is no good for an EFI installation.

Get yourself a proper pump off a turbo EFI car, or a car running mechanical injection and you'll be fine.

Thats what I thought Dave. Carl im running a Puma pump in mine.

Obviously its a submerged pump so you made need to fit an SPI tank?

I believe Johnk uses a Toyota pump in his tank and it has a built in regulator.

Pressure test will reveal all TBH.

I'd say the pump. Easy solution is to fit an MPI fuel tank with built in pump.

are you sure Dave?

I was also under the impression that the same pump was used on the EFI montego/maestro etc.

if it is running the standard ecu ect i would connect up the speed sensor ect. on some peugeots you can run the car fine with the speed sensor off but after a while it will start to run like a bag of shat, missfire stall ect

Searching is all you need on TurboMinis

Do you have a CEL wired up ???

A lot of cars do not like it when their speedo signal dissappears. Limp home mode cuts in after a few miles. I know this is definately the case with Subarus....and good chance Toyota too.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

put guage on tonight. 40psi on idle 50 psi when booting it and 10-20 psi when problem occurs. now i think/hope its a faulty or inadequate pump. ive ordered a new metty turbo pump of ebay (unfortunatly before i read TDs post, Doh)
tried a different pressure reg no different.

theres still a chance it could be down to tise speed signal but im dissmissing this at the moment for 3 reasons=
1) the warning light doesnt come on when fault occurs.
2)obviously the light comes on for no speed signal but fault doesnt seem to corrispond with light.
3)when faults accured if i turn ignition off then back on the ecu resets for speed sensor fault but fault still there.

if i wait 5 minutes drives ok till the next time.

im gonna try a pump 1st and see how we go, any suggestions of external pumps would be appriciated. (easier for me to fit)

thanks

Hi,
90's cavalier SRI or similar, hose tails on both ends.
I got a very grotty looking one of ebay for a £5, works perfectly

merc 2.5 16V cossie 190E one. Same as audi ur quattro, bosch 910 pump. I have one brand new one on the bench here.

Metro pump should be capable ok.....

Is there any chance you have a supply problem ?
What size is the feed from tank to pump ? Is the tank clean ? no blockages ?

or your pump could just be knackered

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

the pump seems to cope when booting car. but after a few miles it starts dying as tho either pumps knackered or its having to work to hard and then getting tyred.

8mm feed, 8mm return no restrickion i can see.
