Recently fitted a brand new fuel pump from autospecialists (not bosch...didnt realise till it arrived! but looks identical!)
Anyway, reason for a new pump was because the old one was drawing current and heating up the positive feed wire to the pump, and that im told means the pump is having to draw more current as its working harder as its fubar!
NOW
Fitted the new pump, and it was still heating up the wire...but gradually its been heating it up more and more until today its burning hot on a short drive, plus the pump sounds like a bag of spanners...
I thought maybe the fuel filter was blocked, so put a new one on, still doing it...could a fuel line be blocked as it sounds like its sturggling to pump..after fitting the new fuel filter it would need to fill that up as it primes, it sounded like a normal pump till the filter filled up with fuel then once it built pressure it sounded like the bag of spanners mentioned before? (I have the fuel relay bridged atm as ive not got a relay) oh car runs but has developed a miss fire, maybe its run lean and fucked my 300 mile old NKG plugs as I hear they have to have a near perfect air/fuel mixture or they break?

im at my witts end, Im not rich enough to keep buying new parts and guessing

Shit mate not good , cars are shit aint they ! really are sometimes

Coldo

One thing after another, just when i think its gonna be A1 for the summer coming, something else fucks up!

sure you have sat the pump the right way
i would have pressure tested it! The whole system! does the pump get enough power/volt?

i

rabmc

As above , what voltage is there mate ? mines was really low on idle around 9.2volts this is my cossie mind , but had electrical problems in the past , sooo redone batt connections and put 3 new earth points around engine bay and it went up to 10.8 volts , still not happy with it though , going to rewire it soon with onwn live feed via relay etc , who knows what it goes to on boost

Coldo, If the cars running yea I should be their! the thermostat housings yours dont worry about the silver

Alex_86, + and - are the right way, connections are the right way, it just sounds like its struggling to pump fuel not a constant bzzz more like a brr brr brr brr

rabmc, havent checked the voltage as ive not got a volt meter it must be getting some tho s it heats the wire I use to bridge the relay up to fuck

Could of done with winning the raffle prize at tonights meet....an hours sesh on AVA's rollers

hm, i do believe it is the volt that is wrong, as u said the pump is brand new!
how does the fuel come out true the fuel filter then? just take of the fuel line from the filter to the meter head,and see if it comes with or without air

Coldo

No worries, if you ain't making it, ill nip up to yours sometime, need it soonish, this daily coolant topping up isnt cool

Personally davvy, i would be having a serious thought about looking inside your petrol tank, because i know mines rotten on my cabby, everything in the fuel system i removed had orange stained fuel inside.................

Ive refitted old pump, everything seems A ok, no exssesive current draw, pump pumps with the normal bzzzzz not loud either...

one problem tho, ive got a missfire under load like I had last time before I changed the plugs, jus regapped them and its still their....NGK BCR 8ES gapped to .75

SafeChav

fuck knows.

Air leak?

Head gasket?

vroooom ptssssh

dont say the head gasket word

it didnt want to restart jus their after I took it out for a roasting, someone take it away and leave me an evo

hm, try to blow the fuel lines clean?

vroooom ptssssh

Seems to only be missing once fully warmed up. doesnt do it when its cold/warmish, so im hoping a plug lead breaking down?

and yes, they will affect the ignition as it may mise fire or/and cut

prob order a set of blue motorsport ones tommo, cheers for help guys

pretty surprised that the brand new pump was fucked, gonna be fun trying to get a refund

as mention'd,


check all fuel lines, and pickup pipe in tank. even tho its sorted itself, chances it will happen again,

and even the miss fire might be because of lack of flow/pressure.

Fiecos Dan

Dont get them, they are not very good at all.

Get a set of 8mm leads from your motor factor's, about £20 and alot better.

i tried motorsport one on my TT, kept getting shocks, and slight miss fire, so put my motor factor items back on. (had them for 40+k miles, and 5 years, and still like new.

Cheers Dan i'll give them a check, I keep meaning to replace the rest of the lines with braided stuff but its just finding the cash

I was thinking of just getting some motor factors leads
