Landrover Defender TD5 2001 - Poor start, code 57 fuel pump drive open load fault - Fixed #

Posted by Lee Pritchard on July 2, 2014, 5:16 pm

Year of Manufacture *: 2001
Engine Size and Code *: 2500
( Optional ) Scanner Used: Pico,modis
( Optional) Fault Codes: 57 fuel pump drive open load fault.

Hi all,

Im struggling to find some info on this td5 low fuel pressure side from the pump. I have a poor start condition hot and cold and a lack of power,its slow reving up.

Carried out a fuel pressure test from pump and it reads just over 4 bar and 2 bar on the return flow.

I have read various different info and some say 6-7 bar from the pump.

Any info would be much appreciated.

Kind regards

Lee pritchard

4 bar from the pump at the fuel connector block/pressure regulator is what it should be. I'm not sure whether the 2 bar on return is a bit high though.
As regards slow revving up, have you tried disconnecting maf?

2 bar is fine on the return.
Does the pump make a horrible gurgling noise when you switch the ignition on, or a screeching? or normal?

Hi,

The pump is making the same noise as other td5`s i have heard. Vehicle came from another garage with a new fuel filter on it (which i have checked for correct fitment of pipes) and a new wiring loom in the head,there was oil in the red multiplug on ecu,cleaned all that off and still same.

It seems as a slight misfire when idling and reving up,will rev up high but takes some time.Fault has gradually been getting worse.

Tests i have done-

Relative compression test..all good.

Checked valve timing.

I have scoped each injector with an amps clamp and they are all the same when idling a reving up.so difference between all 5.

Good quality fuel.

Fuel pressure check (not flow test tho) from pump 4Bar and holds 4 bar when reved,2Bar on return.

Smoked intake system..no leaks

Disconnected and scoped maf sensor,peaks at 4.2 volts..still the same.

Adjusted injector as per spec.

live Data on all scan tools are very poor.

Not much info on testing injectors on these from what i can find. Do not really want to send injectors away due to whenever you seem to send injectors away they always seem to fail etc.

Thanks for reply's

Regards

Lee Pritchard

Monitor the rate of rise on the AMM & the APP

What's the turbo doing?

Usually when an injector is faulty, it just drops a cylinder when running on these.

T4 displays live data for injector balance when running.

Have you tried swapping a s/hand ecu for test purposes?

Hi

These suffer from injector seals leaking combustion gas into the fuel rail in the head. worth checking return from engine for signs of bubbles.

I think one of the above posts was thinking similar as it often results in noises from pump.

One of the ports on the filter housing has a small valve to bleed of small amounts of trapped air.

Also pretty sure there is a gauze filter in the head rail port, which can restrict flow if blocked

Cheers Aidan

Finally fixed

After taking mark advice to scope AMM and APP,upon doing a WOT test there was a loud ticking noise when i floored it and started seriously missing,pulled rocker cover off and found one injector stuck down,suggested to customer to remove all injectors and get them sent off and tested.

After weeks of thinking about it he got a set of second hand injectors and it was still the same,still not listening to me about sending old ones away he left the vehicle with us in our compound for another few weeks and came back again with ANOTHER set of used injectors and it ran the same.

After having a long chat with him he finally came round to agreeing with me to get the injectors tested properly.

Sent off injectors away to darwen and results came back as all nozzles were u/s(prob did not help farmer had been running vehicle on dirty ribena for the last 5 years!!!).

Reconditioned all 5 injectors,fitted,adjusted clearance and coded in and vehicle ran like new!!Classic case of customer trying to keep the job cheap but costing loads more.
Thanks for all advice.
cheers Lee

Glad you got a fix on this.
You mentioned you had oil at the red ecu plug, this will cause misfire etc if left untreated, you need to change the injector harness inside the rocker cover, along with the o ring where it exits the head at the front.
After replacing the harness regular checks need making at the red ecu plug and any oil cleaned away, until the oil stops appearing. If the oil gets into the ecu board it causes all manner of issues.

Take care.

Liam.
