Need help diagnose a problem

E46 is being a headache once again (I hate this car :( )its parked about a mile from the house but at least its locked away securely
Before I even start I know this is a how long is piece of string question

It wouldn't start when my missus came out to it so I drove down thinking it was the battery so I jumped it but to no avail iv eleminated that its the battery as theres plenty of juice in it

It will start for roughly a second then just dies even if I try to rev it it does nothing and just continues to conk out

Any ideas ? Possibly sensor ?

Iv no diagnostics at the moment either for the first time in 3 yrs :@

Is it getting fuel?

I was going to say it feels like theres no juice in it but would it keep starting.

There was no weird noises from the fuel pump before hand or any indication it was about to fail

Is the fuel pump a common failure item on these I wonder

It sounds like an immobiliser issue, I've had it before where a car did exactly the same thing, it had an immobiliser retrofitted, I removed the immobiliser and problem solved.

Other thing that springs to mind is fuel pump, constricted exhaust, cam position sensor or a dead key.

Is it throwing any codes?

If it were immobiliser it wouldn't start at all I thought ?

I dont know brain is fried with it I dont know why I made a thread as its impossible to diagnose it could be a million things il just get it home and figure it out tomorrow

Thanks for the input gents much appreciated

Il report back tomorrow with more info hopefully

In Dundalk we.ve replaced over 6 lift pumps in the past week due to bad petrol.. lift rear seat check to hear if pump is running if not check power on plug if none remove glove box and check relay think its 3rd one in

Cheers eoghan will check it in the morning

Fuel pump!

Also sounds like fuel pump to me. Hopefully is as could be a lot worse!

Cheers never had to replace the pump before whats the options buy new or do people get them refurbished like alternators ?

Il check relay first then multimeter on the pump itself and go from there

Another vote for fuel pump. Sounds similar to a problem I had with the e39 a few months ago.
The alternator is giving me trouble at the minute, being resolved tomorrow.[/i]

Probably not but I've had a Nissan years back with a bad airflow meter .car started but low revs and cut out as soon as it's revved..unplug it to see if there's a difference..any issues leading upto this

Im doing this blindly at the moment iv no proper diagnostics , I have ine of them shitty bluetooth ones I read the car no faults

If removed the rear seat and sound deadening stuff so the pump location os exposed

Should I be hearing a noise from the pump when the car is on red lights ?

Edit: Just watched this have it now will go at it tomorrow to busy today
