acf8181 0 Posted September 9, 2004 Report Share Posted September 9, 2004 ok, i'll start from the beginning, just in case people aren't up to date. went to germany with car down on power, tony at automotive solutions had diagnosed there was no reading from the hall sender, he'd tried a spare sender in it and there was still no reading, so either the spare was also dead, or theres a wiring fault towards the ECU (he tested half the way). anyway, so car was running on safe mode.whilst in germany, on my second lap of the 'ring (and having been very gentle with the car) i suddenyl get the water light flashing. pulled over immediatly and switched the engine off straight away. smoke everywhere, so suspected h/g failure again. got the car recovered back to here (during which they smashed up the rear bumper).discovered that it was actually that the lower casing of the additional water pump had cracked, so not h.g after all. got new water pump and fitted it today.went to start the car, and although turning over fine, it won't fire. like theres no fuel in it.suspected the recovery people had disconnected something...fuse is fine, relay also appears fine. opened the cover in the boot and got the girlfriend to crank it and i couldn't hear any activity from the pump. unplugged the connector from it and cranked the car again...no difference. so that suggests the pump isn't working?how can this have broken now, the car was running fine when i turned it off. is there anything else they could have disconnected to disable the car?

acf8181 0 Posted September 9, 2004 Author Report Share Posted September 9, 2004 see, thats the thing...i've spent so much its not worth swapping it for another, cause i'll have lost that money.if i ever get it running right at least its had timing chains done, and other expensive stuff.

apd 0 Posted September 9, 2004 Report Share Posted September 9, 2004 If you have cranked it with the fuel lines off,but with the electrics plugged in it should pump all day!If not try replacing relay 167[fuel pump].if it does not pump petrol the pumps fucked.Anyway on crank the pump buzzez to prime system.

acf8181 0 Posted September 9, 2004 Author Report Share Posted September 9, 2004 its ain't buzzing.the bit i dont get is that there was no prob with it, i turn the car off cause of the water pump prob, so how can it have packed up when its not being used! Link to post Share on other sites
tandino 1 Posted September 9, 2004 Report Share Posted September 9, 2004 It seems strange that its packed up since youve been delving under the bonnet.....Are you sure you havent disturbed something - ie hall sender/coil connections etc as these (on cars ive owned previously) will cut the fuel pump if not connected....Pete.

apd 0 Posted September 9, 2004 Report Share Posted September 9, 2004 i'd deffo try bumping it just for the process of elimination.as you're bypassing start up. Link to post Share on other sites
antera309 3 Posted September 9, 2004 Report Share Posted September 9, 2004 ACF8181, Many cars (not sure if the Golf Mk3 is one of them) have an inertia switch located somewhere which cuts off the fuel supply if the car is tilted beyond a certain angle or subjected to an impact. They're designed to prevent fuel spillage (and hence fires etc) in the event of an accident.It may be that such a switch got tripped when the car was towed. If they were rough enough with the car to to break the bumper, then it's quite possible.If a car has a fuel cut-off switch, the re-setting procedure will be described in the owner's manual. I can't verify this 'cos I don't have a manual with mine, but it's worth checking out. If it's not mentioned in the manual, then there isn't one.Failing that, diagnose the fuel pump itself by connecting the + terminal of the fuel pump directly to the battery + terminal (with the - terminal connected to the body as normal) and listen for pump activity. Remove the fuel pump relay before you do this.[ Edited Thu Sep 09 2004, 11:04PM ] Link to post Share on other sites
acf8181 0 Posted September 9, 2004 Author Report Share Posted September 9, 2004 it doesn't have one as far asi know either antera, but i'll check the manual later. it would stand to reason though.theres deffo no pump activity. Link to post Share on other sites
andy 0 Posted September 10, 2004 Report Share Posted September 10, 2004 acf, you know the fuel pump isn't operating so..., you need to assertain whether its the pump or the wiring/signals going to the pump that's at fault. Doing as antera309 says will prove if its the pump or not, if the pump seems ok, check the connections going to the pump have 12 Volts present, if they don't then you need to be looking at the relevant relay. What makes you think the relay is ok at the mo? Have you actually measured the output? Link to post Share on other sites

Bullwinkle668 0 Posted September 10, 2004 Report Share Posted September 10, 2004 My car did a similar thing. The problem first presented as intermittently turning over but not firing. Eventually, it wouldn't start at all. Apparently there is a power relay switch renowned at VW Service to stick. It was replaced in mine and works fine. Recommend taking it to a VW Service Centre for full diagnostics. These engines are full of sensors that will prevent starting if they sense something is amiss. I know here in Australia, VW Service costs an arm and a leg but I would still recommend it for something as difficult as this to pin down. Link to post Share on other sites
acf8181 0 Posted September 10, 2004 Author Report Share Posted September 10, 2004 yeah, cause i'm gonna go to vw and get ripped off. my cars 11 years old remember, it ain't worth that much. besides we have loads of independent garages round here. i had the diagnostics checked before i went to germany, and the only fault was the hall sender.i'll check all the wiring...think it tells me how in the bentley.

apd 0 Posted September 10, 2004 Report Share Posted September 10, 2004 if it won't bump,and if you 12v the pump directly and it doesn't work its relay,PUMP or wiring.RELAY 167 FUEL PUMP,109 voltage stab.new 109 relay,starter motor sorted my problem when HALLSENDER fault was diagnosed @ VW.Hall sender fault comes up as a generalisation,its all part of a loop.

andy 0 Posted September 10, 2004 Report Share Posted September 10, 2004 eh? ;-)if you apply 12V directly to the pump and it doesn't work it has to be the pump.......... Link to post Share on other sites
speedo 0 Posted September 12, 2004 Report Share Posted September 12, 2004 Does it have an immobilizer??? Being K plate it shouldn`t have a factory item, but do you have an imobilizer? if so are you sure it`s activating properly? I am only in high wycombe, so if no luck, i could pop over one evening and have a look ... Link to post Share on other sites
acf8181 0 Posted September 12, 2004 Author Report Share Posted September 12, 2004 only has an aftermarket immob...and i know its switched off, cause it wouldn't try and start if it wasn't. Link to post Share on other sites
andy 0 Posted September 13, 2004 Report Share Posted September 13, 2004 some imobilisers imobilise several ccts, just because the starters working doesn't necessarily mean all circuits are mobilised Link to post Share on other sites
acf8181 0 Posted September 13, 2004 Author Report Share Posted September 13, 2004 nah, i know this one...if it hadn't switched off the dash lights wouldn't come on...had it happen before Link to post Share on other sites
andy 0 Posted September 13, 2004 Report Share Posted September 13, 2004 i see..so whats the latest on this then? have you eliminated anything as yet? Link to post Share on other sites
acf8181 0 Posted September 13, 2004 Author Report Share Posted September 13, 2004 er...the fuse is fine!i'm gonna wait till i'm in a good mood before touching it, otherwise i might do bad stuff to it!checking relay is next job. Link to post Share on other sites
Eat this 2 Posted September 13, 2004 Report Share Posted September 13, 2004 i still cant believe u took a slighty knackered car round the ring lol it aint exactly sympathetic ur nuts m8 hehe (id giv my right arm to hav a go though) Link to post Share on other sites
acf8181 0 Posted September 13, 2004 Author Report Share Posted September 13, 2004 well, here's the facts...i'd paid out £300 for hotel and ferry already, which would not be refundable at that late a stage...the car was ok a few weeks before.the car was running on safe mode, not about to die.what actually broke was totally unrelated to anything else that had happened before.i didn't loose a penny more by going, than i wouldn't have lost if i'd stayed at home.

acf8181 0 Posted September 13, 2004 Author Report Share Posted September 13, 2004 oh, nothing to stop you going...only about £500 (unless you stack it like a m3 did just after i broke down - he did ?15000 of damage to the armco) Link to post Share on other sites
