EFi won't start

[Range Rover Blues]

It looks like a niggly little problem that was starting to develop has turned into a full blown breakdown.

My LSE won't start, if you turn the key you hear the pump prime, crank it and it will fire, maybe run fine for a second then stumble and cut out, or just stuble, then die.

When it cuts out you can hear the pump run on for a second then cut out too, yolu can hear the relay inside the dash somewhere.

So I'm thinking fuel problem, it has been stood with the tank empty.

I swapped the fuel filter this morning, now it fires a bit more often but still stumbles then cuts out.

What else should I check :-k

The pump itself working correctly???

Sounds very similiar to one i recently bought and wouldn't run got it to the stage your at now but couldn't cure it..


Would love to know what it turns out to be as i replaced everything off my current running Bobtail onto this other one with no availe..... :x

Oh yeah, cheer me up why don't you ;)

TBH I'm thinking pump too, it has got the tinyest bit better with a new filter so it could be the pump.  It did make a strange noise at one point.  Thing is the pump is running, so is it clogged :-k

I also thought about taking a pipe off under the bonnet and running the petrol through to flush it out, but it went dark.

Does it have the fuel pump inside the tank ?
If you disconnect the fuel filter  and turn the ignition on do you get petrol out of the pipe to the filter? Apparently the EFI is quite a high pressure pump.
On my Disco last year the fuel pump packed up.
I could hear the pump start up on ignition though. When I took out the pump it had like a strainer/bag thing over the inlet to the pump which was dirty as hell, and even though the pump would spin up it had no real pressure. Found a second hand one off ebay for £30.00 so wasn't so bad in the end.

Disconnect the fuel line and stuff the air line down it,it did the job on my 200!

I wouldn't go in gung-ho with that idea on a petrol EFi, you risk ruining the pressure regulator

Mine's got an aftermarket pressure reg because it's uprated.  I can attach a pressure gauge to it for setting up so I might do that.

Will an EFi pump stand air being blasted backwards through it :-k

Hotwire? Check the black/white wire connection the -ve of the coil, pretty classic symptoms.
