300 Tdi no fuel at injectors

Langers · Dec 18, 2012

Hi all

In the process of getting my freshly fitted 300 Tdi going.

I've bled the fuel system in the following way so far;

- Cracked off fuel filter bleed screw and got fuel coming through there. Filter is full.

- Cracked off injection pump return line and got plenty of fuel coming through there.

Now, there isn't any fuel coming through the injector lines at all when turning the engine over.

Stop solenoid clicks when 12v is applied and turned off.

Anything I'm missing here?

N.b. engine is a late-ish Defender one, code 23L.

Thanks muchly!

If nothing is getting through the injectors are they getting their feed signal to open ?

aaaaah :scratching_chin:

I have pump deuce injectors on mine so they need leccy to make them open and shut

Not on the landy on the other diesel, but we've been working with injectors at uni and some of the non deuce ones need a leccy feed too

Thats cause yours is a petrol v8 :doh:

I'd be tempted to remove the stop solenoid and check it working, if in doubt refit it without the plunger, if still no fuel at injectors it's gotta be a goosed injector pump.

Will give that a go. Cheers

Might be a sticky stop solenoid - remove the solenoid - remove the plunger - replace the stop solenoid - start engine (stall engine to stop)

Nope the 300tdi's don't have carbs either

No but I thought it might have leccy injectors like the ones I've got on the other car and like the marine ones we were playing with in workshop

fail

injector pump is turning ?not edc ?,could be knackered pump as previously said ,but worth removing injector pipes and undoing each outlet (delivery valve )in turn cleaning and putting back in ,

tdi still uses rotary distriution pump not common rail or unit injectors

Ere! Langers, are we all correct in thinking your 300Tdi is a manual vehicle and not auto?????????????????

DEFENDER90-DAZ · Dec 18, 2012

I presumed it was a manual and not auto being a defender ..................

If it is an auto don't do the solenoid plunger removal as you can't stall an auto easily..........

We had the exact same problem after we did an engine swap on Bump's Disco earlier this year.
Long story short, there was stray, single black earth wire which we hadn't connected near the fuse box on the inner wing. Put that back in its place and it fired up straight away.
