E34 540i problems

[maxfield]

My dad removed the immobiliser from it now the fuel pump works sometimes and other times it doesn't, any help would be appreciated.

A wiring diagram would be nice too

Thanks,

Jamie

[CraigG]

why did he remove the immobiliser? that was just destened to run into running problems no?

[Davenotouring]

Here is a wiring diagram, the problem area is in red.

[Davenotouring]

The wire from the sensors to the ECU is too thin also, check that out.

[maxfield]

It was an aftermarket immobiliser which was causing all sorts of problems.

Dave i think your problem is in your head

[Davenotouring]

You're not wrong there.

He's probably putting diesel in again Janice.

surely dave, the pump needs a signal from the ECU to tell it tio initiate pumping....

amateur!

Max- likely that the Imobiliser is wired in some way to the ECU or pump and is stopping them working/sending correct signals!

[maxfield]

He's probably putting diesel in again Janice.

Would still run on it, they're rather thirsty

[Davenotouring]

No, the pump is always activated. The ECU just tells the injectors when to open.

[maxfield]

No, the pump is always activated. The ECU just tells the injectors when to open.

The ECU on the 540i probably tells them to stay open all the time

[CraigG]

No, the pump is always activated. The ECU just tells the injectors when to open.

a common method for immobilizing a vehicle is to cut the feed to the pump, no fuel, no go. so if he has just removed an immobilizer, that problem should be staring him in the face, check all the wiring from where he removed the immob to the pump(ie physically trace the wire) pump should be fairly straight forward tho, a live feed from the battery (this is where the immobilizer should be spliced into..)

Stop f*cking around and call an auto electrician...

[maxfield]

Stop f*cking around and call an auto electrician...

[stuartgallafant]

Oh yes, I forgot there are no auto electricians in Spain.

[maxfield]

You're in Spain???

The car is

Not many English ones.

[Davenotouring]

You should get a Spanish one, learn to speak the language if you live there! Or get a translator!

[maxfield]

I don't live here my dad lives here and there.

I've learnt Spanish the last 2 years at school and hardly know nothing.

[Davenotouring]

El electricista

[maxfield]

The electrition

I learnt a bit i suppose.

[Davenotouring]

Wish I spoke Spanish, I'd fly over and help you! haha!

[maxfield]

The cars a turd!

Sounds nice tho

[Davenotouring]

Get a Haynes Manual!

[maxfield]

He said he's getting one before he goes back.

But help from here would also be nice

[Davenotouring]

You learnt Spanish for two years, but can't speak it at all?

Fu**ing school! Great!

[maxfield]

It certainly was

All we did was talk about the weekend.

Learned a bit

[stuartgallafant]

i went to Isla de Margarita for 2 weeks and learnt more spanish then, they you obviously learnt in 2 years!!!

[daimlerman]

I reckon the problem is that the Spanish cannot speak maxfield....

[maxfield]

Maxfield speaks English

Looks like we should give Jock a call

[stuartgallafant]

I reckon the problem is that the Spanish cannot speak maxfield....
