Vr6 wont start.. getting no fuel...

[Ben J]

Hey guys.

So i got around to putting in my new oil pump and sump ect last night, went to start it up, and no luck what so ever :/ Ive been trying to get the stupid thing going for ages and its starting to get annoying. Im pretty confident it has nothing to do with the new bits though...

It turns over fine and I'm getting spark, but not fuel.. Ive tried jumping the pump through the relay as described in the bently and still get nothing. So i tried putting some voltage straight to the pump and sure enough it works... According to the bentley this should mean I have a problem somewhere in the wiring from the relay -> pump, which i fear, as the wiring in my car is a mess :/

While the car was off the road I also pulled out the evap charcoal canister thing, bypassed the isv muffler and pulled out an aftermarket cruise control and alarm.

I'm not to sure where to go from here... anyone had a similar problem or have any ideas of things I can try to try and narrow down the problem? I really want to hear my baby purr again :S

Dont use Bentley , only OEm so cant comment on their test procedure, but have you bridged the 2 large contacts on the fusebox that the relay fits into??? One side is 12v and the other goes straight to the pump. . You will also have to make sure there is in fact 12v where it should be. This is essentially what the relay does anyway, but protects the circuit like a whopping big fuse as it should .
See how you go,

From memory I think its relay 167 that runs the fuel pump. Ive sold 2 this year already so they are becoming a common failure part.

[Jmac]

Yep 167 is the animal im referring to. bridge the 2 large contacts and it should run if not then you are going to be checking the wiring.

Alright cheers guys, I had bridged one contact to the battery as the bentley suggested but will try just doing the 2 on the relay (which makes more sence now I think about it...)

Will check it out tomorow. Whats a relay cost WhiteVR6? Im sure theyd be cheap over seas but im sick of playing the waiting game.

Oh how I hope its not something in the wiring :/ mines a mess from all the aftermarket alarm/cruise/ect previous owners had put in. Everything was working fine before I took the car off the road, so wouldnt it be weird that the relay would just stop working (if thats what it is)

Just another thought, the alarm you pulled out, do you know how it immobilised the vehicle? If it was wired to cut the fuel pump you might have inadvertently left the fuel pump wiring with a break along the lines from where the alarm intercepted it.

[Ben J]

Thats what im fearing WhO :/ The alarm was useless, I disabled it the day I got the car, Im pretty sure it was about 16 years and so I pulled it out to tidy up the engine bay. I guess I'll have a good look, but all that wiring confuses the hell out of me, how are you meant to tell which is what in a bundle of like 200 wires...

I'll do some more tests and maybe try and follow the wires off the fuel pump relay to see where they go and if there is some sort of imobiliser thing, problem is I cant seem to get the fusebox out far enough to see the back of it.

[Jmac]

Absoultely right, didnt realise you had an aftermarket alarm, man these things were the root cause of many starting dramas. Just check where they tapped into, normally one of the lower lugs on the rear of the fusebox, im sure the wire colour is red/black from memory. Makes loads of sense if you can power probe the pump and it runs. Some guys tap that wire just behind the right hand kick trim at the bonnet pull handle, if the fusebox is in the too hard basket for them.
See how you go

ps ive got full set of wiring diagrams if you need pin outs etc

[Ben J]

Alright, got off work early this afternoon so will head out and see if I can sus it out

i have read that fuel pump realy 167 a common failure part.... from memory the ones made in portugal (not 100% sure)
Youtube has a Test a fuel pump relay video
(this is from memory, not 100% sure) If you can bridge like jmac states and see (bypasses relay), then half plug it in and get a probe on the negative side and bridge that to the car body or a negative (tests to see if your wiring is bad in back of fuse/relay panel)
