it turns over fine but just wont fire
has been running this week fine, i have checked and there is a spark to all leads and plugs
i pulled the pipe off the end of the fuel rail and tried firing it and no fuel came through
First of all, check the fuel pump relays (poor contact or even broken)
If there is no pump relay problem you have to replace the fuel pump
where are the fuel pump relays and what do they look like
is it the 2 little boxes near the ecu
Yes mate, these 2 little boxes that are next to the ecu, also check the single one that's over the fuse box...
checks the 2 boxes, how can i tell if these are working or not
they were both connected fine, one had a little bit of green on it but i cleaned all the terminals and refitted but no joy.
i will go to check the other little box now
cleaned all the terminals of the box above the fusebox and still wont start
there was a white connector coming from a red cable with a fuse which had blown with 5amp fuse with radio/charger writtn on it
any ideas what i should do next
check the wiring between the yellow blade fuse on top of the fusebox and the red/yellow wire to the fuel pumps. There's a diagnosis thread in one of the FAQ sections with more details in it, have a read of that.
looked at the FAQ's and i realised that i adjusted the idle screw but didnt do this as described in the FAQ's. could this be a problem
that's not going to affect the fuel pumps running. It's going to either be a dead pump, engine bay to pump wiring, that fuse, fuel pump relay, ecu issue....
im finding it weird as it was running beautifully yesterday, decided to take the battery off to charge it and now it wont start with the battery charged.
if there was a problem with the pump or fuel system in some way surely it would have cut out yesterday. gutted i wanted to get it sorted tonight so i can move the car so i can take my bins out and they are full. oh well
the yellow fuse is fine
aint got a multimeter to check the wiring
cant really hear the pump priming at all
if its got a spark then the distributor should be ok i assume
i hate problems like this, but when they are sorted you have piece of mind that that part is new
go to VW and buy a new relay and try it to see if it solves the problem, if not then it may be your fuel pump but they uaually die slowly rather than all of a sudden.
so i need to ask for a new fuel pump relay
are they expensive and are they g40 specific. my local vw aint much kop
fuel pumps are cheap enough at vw, checked today
i have a feeling its the immobiliser not desarming, is there any way to bypass it to see if its that
checked the car again earlier. im sure its the toad ai606 alarm/immob playing up, when you usually switch the alarm off the red flashing light turns green. instead its turning orange. plus when i switch the alarm off the water temp light flashes twice. i know these usually mean things but i aint got what the water temp light flashing twice then going off means.
i have looked into the toad ai606 on internet and it suggests by looking at other forums that other people have had this problem. just after the battery has run low
fuel pumps cheap at VW?
if you see them as cheap then i strongly advise pay a mechanic/auto-electrician to look at the car since you clearly arent able to diagnose issues yourself
will save you causing yourself more problems
my mate who is a vw mechanic is coming over this week to have a look at it. im sure that im going to need an auto electrician instead though. i will have to see what he says. just hope its nothing serious.
i also have a mate auto electrician who is popping over 2moro night
sorted now
was fuel pump relay
cheers for all the advice guys
