Hello all,

Bassically my fuel gage isn't working - but the car is still running fine!!

My guess is that the fuel pump connections have broken/corroded on the actual pump!! Now here is the question - can someone please tell me where my fuel pump is (a pic would be good) and which terminals each colour wire goes to please??

Hope it is this otherwise my dash is coming apart

Cheers,

Dumpy

Should also ask it is a S1 engine in a S2 shell!!

The fuel gauge has nothing to do with the pump if your gauge aint working then it's either the gauge in the dash is fucked or the sender in the tank

Dumpy

Damn more of an issue than i thought!!

Cheers for that i shall have to look for the connections on the fuel tank then - where will the wires be on this??

FFS!!

Cheers,

Dumpy

Id try changing the gauge in the dash first mate because if the sender is gone then that means you need to drop the tank

Dumpy

Cheers Buddy - looks like i'm a bit fooked really as M.O.T is due next month!!

Smeg!!

Cheers,

Dumpy

Dumpy

Here's another question - i'm sure i saw a picture of an engine that arrows to the parts of the engine and what they were - does any one know where this is or seen it??

Cheers,

Dumpy

Whats the fuel gauge go to do with the MOT?

Dumpy

Suerly if it is showing empty when the tester is in the car and still running it will show some cause for concern - hopefully i am wrong!!

I thought that if it shows below the limit it would fail!!

I hope i am wrong on this however!!

Cheers,

Dumpy

OMG this has gotten very messy already!

Back to basics..........is your car an MFI RST firstly......

Dumpy

I beleive so - i do appologise SafeChav, never owned a turbo or anything with any power really, so if i get a photo of the engine would somebody please tell me where the locations of some parts of the engine are and wheteher it is MFI or EFi!!

Sorry for my thickness/inexperience!!

Cheers,

Dumpy

fast_ford_uk

the fuel gauge is not an mot failure

davsmith64

ok look at your engine bay.. does it have a distributer? also at the right hand side of the bay does in have a metering head with red pipes coming from it to the inlet manifold..i.e. injectors

Easiest way to tell on the engine is if it has a big EFI stamped onto the big metal bit at the top of the engine as you look at it.

SafeChav

Dumpy no need to appologise mate, i just meant it was getting a bit outor proportion for something that is more than likely an easy fix

Now.....if you pull the rear seat bench forward, i THINK there is a multiplug just before the loom goes through the grommet in the bodywork.

Can you just have a quick look and see if there is before i carry on

Well durrrrrrrrrrr

rs shawn

Shit off you..he said he didn't know and this to me is the easiest and quickest way
<<< Have it.

SafeChav

Ave it, you slag

Dumpy

Sorry to interupt your flirting gents

I have taken the bench up took a photo on my phone and forgot my cable to get it on the PC

But looking at it there is a black plastic connector with a yellow and red wire into it!!

Looking at the engine i did not see any writting on it saying EFI but i have a photo here; i think MFI;

Hopefully it will work!!

Cheers,

antony215

MFI my moneys on the sender being fucked

rs shawn

antony215 Agree..and agree
Live with it if you can Dumpy...unless the tank itself is rotten/rotting then replace both at the same time.

Dumpy

Whats the sender?? Only had the car a couple of weeks!!

Well pissed off - how easy / difficult is it to change one of these??

Cheers,

Dumpy

antony215

The sender is a small float(more or less) that sit's inside the tank it send's a signal to the gauge to let you know how much fuel is in the tank. To get to the sender you need to drop the tank.

Dumpy

Cheers buddy,

Will see why safechav wanted me to check the wires under the bench!!

Cheers,

Dumpy

antony215

yeah see what "THE PROFESSOR" has to say

SafeChav

To do probably the most basic and easiest test there is for a fuel gauge ANTONY

So is there a multiplug under there?

Dumpy

Looks like it - it is a black plastic connector with - see my paint drawing lol;

http://s93.photobucket.com/albums/l5...underbench.jpg

Orange bit is a plug - grey bit is a metal connector!!

Yellow wire looks like it loops but i cant remember wether it does or not!!

Sorry for being a muppet!!

Cheers,

Dumpy

SafeChav

Nah that surplus plug is for a fuel computer (thought the drawing was quite good actually )

Thinking about it i dont think the mk4's do have the plug being as the sender is top mounted.

What your locking for is a Brown/Black wire....can you see it?

twinkle_2k86

come on savechav. use you eyes

SafeChav

Spot the deliberate mistake if i cant use my eyes numb nuts.

The reason i ask again is because he says theres a yellow wire under there?! Never will there be a yellow wire, if that plug is what i think, they will be Brown, and Brown/Red so ave that PROFESSOIR ANTONY

Dumpy

Sorry mate car is in my garage i'm at work so i will have to look and post pics with all my cables tomorrow!!

But these cables look pretty yellow and red on my phone - will take a few pics and see what i can find!!

I'm being proper stupid here but like i say i shall check it!!

Appreciate it gents!!

Dumpy

antony215

SafeChav i know what plug your on about this one

Dumpy

The plastic thing is the same - but the wires are the diffent for sure i'll have to get a photo up!!

Cheers,

Dumpy

SafeChav

Appologies where its due, that wasn't even you that said that Antony

Damn you TwinkleTwinkleLittleStar

That is the plug though yes, and thats for a fuel computer. And no there isn't the plug i was hoping for

Basically the test you want to do, is bridge the Brown/Black wire to earth, and the gauge should read a full tank, if it does, the sender is probably gone, if not, its probably the gauge

rs shawn

See pic below for tank diagram
The sender is number 10/11/12 and has a float attached at the bottom which goes up & down with the fuel level. This movement is turned into an electrical signal..which is fed to your fuel gauge.

They are easy enough to change: but you have to remove the petrol tank as it fits into the top...hence why I said if you are happy to run with it like that then leave it unless your tank is rusty and needs replacing aswell. Do both jobs in one go to save messing around and labour costs. New tanks are around Ł60-70 ish. Senders guessing around the same: but not sure if you can buy new items: might have to be 2nd hand. If you do change the tank/sender, then get the brake lines checked along that side of the car: they run along the top of the tank and it's a tank-out job to replace them if they need doing. Get them done at the same time also

BUT

Ensure it is not an ELECTRICAL fault first..as Safechav is trying to establish..as you don't want to be changing the sender if it isn't faulty.

SafeChav

Sorry Shawn but that diagram was bugging me (you know what a fussy cunt i am)

antony215

SafeChav think you still need a pair of these



I know what other plug your on about (i think) sort of like the one above but it's for the fuel gauge. I couldn't see one on mine and i did feel under the carpet (as far as i could get my hand without taking the backseat/carpet out ) so you may be right they might not have them MFI anyway unless it's farther along the loom(but i wasn't going to take my back seat out to look ) or it may only be the EFI escorts as i swear my old XR3I and ORION (EFI) both had the plug you on about

rs shawn

SafeChav Fussy cunt
Have removed my pic, but left the description. Couldn't find the proper pic, so found one suitable-ish to explain it.

Was the description ok for you tho??

SafeChav

antony215 that was good of your mrs to let you post the picture up Say hi to her from Andy (Last weekend oh yeaaaaaaaa)

The plug i wasn't too sure about, i thought it might not have it being as the sender is top mounted, on the MK3's you can unplug it all and its a short loom, a nice feature IMO. Its been a while since ive had a MK4

rs shawn well now you mention it the description was a bit boring and long winded but i didnt want to hurt your feelings

antony215

Yeah i know what your on about it's got about 6-8 inch loom from the sender then theres the plug that plugs into the rest of the loom more or less the same sort of thing as the picture i posted im sure ive seen it on a mk 4 maybe the early ones

That all depends on what you've been led to believe 6" is mate
